Drinking water has been distilled from sea water since at least about AD 200, when the process was clearly described by Alexander of Aphrodisias.Its history predates this, as a passage in Aristotle's Meteorologica (II.3, 358b16) refers to the distillation of water.Captain Israel Williams of the Friendship (1797) improvised a way to distill water, which he described in his journal. In chemical and biological laboratories, as well as in industry, cheaper alternatives such as deionized water are preferred to distilled water. But if these alternatives are not pure enough, distilled water is used. If exceptionally high purity water is required, double distilled water is used. Distilled water is also commonly used to top off lead acid batteries used in cars and trucks. The presence of other ions commonly found in tap water will drastically reduce an automobile battery's lifespan. Distilled water is preferable to tap water for use in automotive cooling systems. The minerals and ions typically found in tap water can be corrosive to internal engine components, and can cause a faster depletion of the anti-corrosion additives found in most antifreeze formulations. Distilled water is also preferable to tap water for use in model steam engine boilers and model engines of other types.[citation needed] Mineral build-up resulting from the use of tap water in model boilers can severely reduce the efficiency of the boilers if run for long periods. This build-up is known as boiler scale. A boiling water distiller. Boiling tank on top and holding tank on the bottom. Some people use distilled water for household aquariums because it lacks the chemicals found in tap water. It is important to supplement distilled water when using it for fishkeeping; it is too pure to sustain the chemical reactions needed to support an aquarium ecosystem. Distilled water is also essential for use in cigar humidors. Mineral build-up resulting from the use of tap water (including bottled water) will reduce the effectiveness of the humidor. In contrast, some home brewers who want to brew a traditional European Pilsner will dilute their hard water with distilled water so as to mimic the soft waters of Pilsen. Another application was to increase the density of the air to assist early airplane jet engines during takeoff in "hot and high" atmospheric conditions, as was used on the early Boeing 707. Distilled water is also used in Constant Positive Airway Pressure (CPAP) machines to humidify the air entering the user's nasal cavity, mouth, and throat. Distilled water will not leave any contaminants behind when the humidifier in the CPAP machine evaporates the water. Distillation removes all minerals from water, and the membrane methods of reverse osmosis and nanofiltration remove most, or virtually all, minerals. This results in demineralized water, which has not been proven to be healthier than drinking water. The World Health Organization investigated the health effects of demineralized water in 1980, and its experiments in humans found that demineralized water increased diuresis and the elimination of electrolytes, with decreased serum potassium concentration. Magnesium, calcium, and other nutrients in water can help to protect against nutritional deficiency. Recommendations for magnesium have been put at a minimum of 10 mg/L with 20–30 mg/L optimum; for calcium a 20 mg/L minimum and a 40–80 mg/L optimum, and a total water hardness (adding magnesium and calcium) of 2–4 mmol/L. At water hardness above 5 mmol/L, higher incidence of gallstones, kidney stones, urinary stones, arthrosis, and arthropathies have been observed. For fluoride the concentration recommended for dental health is 0.5–1.0 mg/L, with a maximum guideline value of 1.5 mg/L to avoid dental fluorosis. Water filtration devices are becoming increasingly common in households. Most of these devices do not distill water, though there continues to be an increase in consumer-oriented water distillers and reverse osmosis machines being sold and used. Municipal water supplies often have minerals added or have trace impurities at levels which are regulated to be safe for consumption. Much of these additional impurities, such as volatile organic compounds, fluoride, and an estimated 75,000+ other chemical compounds are not removed through conventional filtration; however, distillation and reverse osmosis eliminate nearly all of these impurities. The drinking of purified water as a replacement for drinking water has been both advocated and discouraged for health reasons. Purified water lacks minerals and ions such as calcium that play key roles in biological functions such as in nervous system homeostasis, and are normally found in potable water. The lack of naturally occurring minerals in distilled water has raised some concerns. The Journal of General Internal Medicine published a study on the mineral contents of different waters available in the US. The study found that "drinking water sources available to North Americans may contain high levels of calcium, magnesium, and sodium and may provide clinically important portions of the recommended dietary intake of these minerals". It encouraged people to "check the mineral content of their drinking water, whether tap or bottled, and choose water most appropriate for their needs". Since distilled water is devoid of minerals, mineral intake through diet is needed to maintain good health. The consumption of "hard" water (water with minerals) is associated with beneficial cardiovascular effects. As noted in the American Journal of Epidemiology, consumption of hard drinking water is negatively correlated with atherosclerotic heart disease.

Recent Scientific Studies Have Exposed Dangers of Pool Chemicals We swim in pools because they're safe, right? Not so fast. New studies reveal that your swimming pool may turn out to be the most dangerous water around. Researchers have compared the risks of some chemicals to second-hand smoke. During typical chemical disinfection, chlorine and other chemicals react with organic matter to form hundreds of new chemicals that have been linked to asthma, allergies, and even cancer. There is good news though. New technologies are making our pools safer than ever before. Guanyu nurtures your pool water back to health with ultraviolet light. But lower chemicals are just the beginning. UV pool sanitation is like pressing the reset button, so your pool can be its best. UV is the non-chemical technology used by Many Citys to purify drinking water. The results are equally impressive in swimming pools. You'll enjoy a pool that is safe, healthy, and a lot easier to manage.

UV Ballast or Controller Unit - This is the [brains" of the UV system. Some systems have a very simple controller, and others have a more complicated system that includes alarms, lamp change timers, trouble indicator lights, and more. Although UV units vary in complexity and size, all controllers do basically the same thing of controlling the electrical output of the lamp and powers the UV-C light needed for water purification. Inlet for untreated water. UV Chamber - This part of the system houses the UV sleeve and lamp, and also controls the flow of water through the system. Outlet for treated (clean) water. UV Lamp (or bulb) - The lamp of a UV system produces UV-C, which is UV light considered to be germicidal. However, different lamps perform different functions, so they type of lamp used will be contingent on the application and disinfection requirements UV Quartz Sleeve - The quartz sleeve of a UV system is the long, cylinder-shaped tube. The tube is made of quartz glass and is there to protect the UV lamp which is powered by electricity from the flow of water. The UV lamp transmits light through the tube into the water. It is important to clean the sleeve (generally when the lamp is changed) as minerals and contaminants in the water can cloud the glass tube. UV Sensor - Available option on most UV systems, the UV sensor monitors and indicates the intensity of the UV light. If the intensity becomes too low, even though the lamp is on, an alarm is triggered. Solenoid Valve - Available option on most UV systems, the solenoid valve automatically shuts the water off if the system is not functioning properly, preventing the possibility of contaminated water flowing through the system that is not treated properly. Flow Meter - Standard on some UV systems, the flow meter calculates the actual real-time UV dose delivered for a particular flow rate, ensuring water is treated properly.

Ultraviolet or [UV" is a type of energy found in the electromagnetic spectrum, lying between x-rays and visible light. Although we cannot see UV light or rays, we are exposed to them every time we step out into the sun. In fact, UV light is responsible for causing sunburns. UV Water Purification systems use special lamps that emit UV light of a particular wavelength that have the ability, based on their length, to disrupt the DNA of micro-organisms. These UV light waves are also referred to as the Germicidal Spectrum or Frequency. The frequency used in killing micro-organisms is 254 nanometers (nm). As water passes through a UV water treatment system, living organisms in water are exposed to UV light which attacks the genetic code of the microorganism and rearranges the DNA /RNA, eliminating the microorganism's ability to function and reproduce. If a microorganism can no longer reproduce, it cannot replicate, therefore it cannot infect other organisms with which it has contact. This process of exposing water to UV light is simple but effective, destroying 99.99 percent of harmful microorganisms without adding any chemicals to water.

I produced Drinking Water UV Sterilizer (hereinafter referred to as ultraviolet disinfection) working principle is to use a wavelength of 225nm-275nm UV role in the killing of microorganisms for the water to be purified. When water flows through the disinfection by ultraviolet light, water, bacteria is killed. First, the product features: 1, ultraviolet disinfection sterilization speed, the effect does not change the water physical and chemical properties do not increase the water taste and odor, no carcinogenic chloroform, once installed, easy to operate, easy management. 2, UV sterilizer cylinder using high-quality food grade stainless steel plate processing, service life is 5-10 times that of aluminum products, high pressure, metal ion contamination. 3, UV germicidal lamp selection of the identified state health departments, epidemic prevention departments of professional products, low-voltage 30w, main lines 235.7nm, the highest rate of this wavelength ultraviolet disinfection, more than 98%, and low power consumption, continuous service life of up to 3,000 hour or more. 4, and electrical control box with one design, appearance, save space.

Swimming Pool Water UV Sterilizer has taken special high intensity when no ozone UV germicidal lamp and the inner wall of specially treated carbon micro smelly's stainless steel cylinder, the outer cylinder with a special polishing treatment, the pretreated water flows through the barrel is irradiated with a sufficient amount of 253.7nm ultraviolet line, it has a good bactericidal effect, but also effectively reduces the influence of ultra-pure water. Swimming Pool Water UV Sterilizer Features 1.304 or 316 special polished stainless steel reactor 2. The quartz sleeve to ensure excellent operating temperature 3. sterilization comprehensive, efficient fast, sterilization rate of 99.9%? High output, physical sterilization, the role of non-attachment, no secondary pollution 4. stainless steel shell, European technology, special polishing wall, do not stay dead. 5. Clean equipment, electro-polished, for high clean environment. 6. Electrical equipment configuration suitable for world markets. 7. Special appearance design, easier to use

Size and type of organism: Theoretically, UV radiation can kill viruses, bacteria, algae and protozoa. In general, larger organisms, such as protozoa, require a higher dose of UV radiation than organisms such as bacteria. But there are also differences between the various types of organisms of the same type: some bacteria are more resistant to other ultraviolet radiation. Power of the lamp: The amount of UV light generated by the lamp is reflected in the wattage of the bulb. A lamp with a higher wattage produces more ultraviolet light. The ability of the germicidal fluorescent lamp to produce UV light decreases with age, and in most cases, the bulb needs to be replaced every 6 months. UV light is best produced at a temperature of 104-110ºF; cooler will result in less output. UV penetration: If the UV light can not penetrate the water, it will not be effective. Higher water turbidity will decrease penetration. UV sterilizers should be placed after the biological and mechanical filters so the water is as clear as possible when it enters the sterilizer. Salinity also affects penetration; UV light penetrates freshwater better than saltwater. Finally, cleanliness of the lamp or sleeve is important. If a film or mineral deposit covers the lamp or sleeve, the light will be partially or totally blocked. The distance of the lamp from the water also influences the effectiveness. UV light will only penetrate clear saltwater to a depth of 5mm. Contact time: The longer the amount of time the water is being exposed to the UV light, the more killing power is available. The contact time, sometimes referred to as "dwell time," is influenced by flow rate of the water: slower flow rates increase contact time. The length of the bulb also affects the contact time; with a longer bulb, the water is in contact with the UV light for a longer period of time. Another variable to consider is the turnover time (amount of time required to have the entire volume of water in the aquarium pass through the sterilizer). Since the "sterilized" water constantly mixes with the water in the aquarium as it returns, it is impossible to "sterilize" all the water in the aquarium. That would only be possible if all the water would be removed, sterilized, and then returned to the aquarium at one time. This may result in sterilized water, but would certainly raise havoc with the aquarium inhabitants! Calculating turnover time is mathematically difficult, but can be approximated with the following formula: 9.2 x gallons in tank = number of hours for one turnover flow rate in gallons per hour Temperature: UV light is best produced at temperatures of 104-110ºF; cooler temperatures will result in less output. Quartz sleeves help to insulate the bulb from the cooler aquarium water and thus maintain a higher UV output.

Application of UV disinfection in water Advantages (1) UV Sterilizer sterilization technology with high efficiency, safe and reliable operation, secondary pollution. (2) for Cryptosporidium and Giardia have effects of ultraviolet disinfection effect of chlorine conventional UV Sterilizer technology for Cryptosporidium and Giardia inactivation low and will be at a higher chlorine dosage a large amount of ultraviolet disinfection byproducts, and ultraviolet disinfection at a lower UV dose for Cryptosporidium and Giardia can achieve higher inactivation. (3) do not produce harmful ultraviolet disinfection by-products, without changing the characteristics of organic matter, and because of not adding chemicals, does not produce harmful byproducts, and will not increase the AOC and BDOC and other biological damage to the water pipe network stability byproducts. (4) to reduce odor and degradation of trace organics, trace organic compounds in water by ultraviolet rays have a certain ability to degrade and can reduce water smell and taste. (5) Small footprint, easy maintenance, low cost. 50,000 tons of sewage daily UV disinfection with chlorine, the need to build a 130 meters long, 3 meters wide exposure canal. Ultraviolet disinfection is only 20 meters long and 3 meters wide area; ultraviolet disinfection operation and maintenance simple, low operating costs, up only 4% yuan per ton of water or even lower its cost performance has a great advantage. (6) the effect of UV Sterilizer by water temperature, pH little influence. The survey found that in urban water efficiency is very low. Six cities currently only 7.2% of the respondents home installed water. And nearly six of the respondents expressed the hope that the family can be installed in the water. Beijing public's willingness to install water strongest, followed by Shanghai. Respondents generally expressed the hope that the Government can promote the use of water, sewage strengthen, promote water conservation, promote water-saving measures to punish those who waste to address the city's growing water crisis. Water reuse use of physical and chemical methods, the process flow as follows: Raw water → grid → regulating pond coagulation sedimentation tank → → → ultrafiltration ultraviolet sterilizer (or ultraviolet disinfection sterilization) → water By physical and chemical methods of UV disinfection in water due to serve a large number of agents in the preceding process, resulting in excessive bacteria, and only after ultraviolet disinfection, water quality standards, in order to discharge or use.

Water disinfection of municipal water treatment is an important part. Existing municipal water treatment disinfection technology include the following: 1.Cl preparation and chlorine for water disinfection use Cl to a method for water disinfection is still widely used were, people compare it to the principle of disinfection Familiar with. Water disinfection of municipal water treatment is an important part. Existing municipal water treatment disinfection technology include the following: 1.Cl preparation and chlorine for water disinfection Cl use to disinfect water is a method still widely used, for its people are more familiar with the principles of disinfection. Use chlorine to disinfect the water, which is mainly through oxidation of HClO sterilization, because hypochlorous acid HClO is a small neutral molecule, so it can diffuse into the surface of the negatively charged bacteria and bacterial penetration bacterial cell walls into the interior, to play its role within the bacterial oxidation enzyme system in order to kill bacteria destruction. Chlorine is a toxic, highly corrosive chemicals, therefore, its storage and transportation or use them, we must be strict management, it is usually in relatively large water used in treatment plants. Compared to chlorine to chlorine preparations safer, but bleach valid Cl easily broken down, resulting in the use of inconvenience; NaClO can not be stored, must be used in the field, and its gas production is relatively small, limited aspects of the its use is not so widespread. Cl can be sterilized at a faster rate in the presence of water to kill the bacteria, the cost is not very high, but in the process of sterilization Cl easily produce some harmful substances, these chlorinated organic pollutants in the form of organic chloride after only makes water easy to produce odor, and this toxic pollutants and carcinogens on safety of human life threat. 2.ClO2 for water disinfection ClO2 is a strong oxidant, it has a good adsorption capacity and ability to penetrate the cell wall of the cell wall, it can be effectively and quickly into the destruction of the bacteria inside their enzyme system, so as to achieve rapid bactericidal effect, and therefore the use of water ClO2 disinfection regarded as an ideal method, which combines the advantages of other disinfectants. Because ClO2 is an oxidizer, not a chlorinating agent, therefore, it is a lot of organic matter in water and do not react if the reaction has just generated a product of oxidation, will not cause pollution, sterilization and disinfection of ClO2, far far more than the use of Cl and chlorinating agent disinfection. 3. The use of O3 in water disinfection Application of O3 disinfection technology can effectively sterilize and disinfect the water, because it generates less harmful substances, while enabling increased dissolved oxygen, to achieve water discoloration and deodorization, can kill the algae in the water, can also be Mn decomposition and oxidation of water, detergents, pesticides and organic pigment particles and suspended, thus making the water quality has been greatly improved. The main problem using O3 disinfection to be solved is that its production equipment is relatively large, production processes and more complex, its level requirements of operation and management is relatively high, O3 system to take productivity is relatively low, the consumption of electricity is relatively big, big infrastructure investment, the cost is relatively high; in addition, O3 is an unstable gas, it is easy to break down in water. Therefore, the use of O3 alone is difficult to ensure continuous disinfection sterilization effect. 4. The use of ultraviolet light to disinfect water UV can be changed ribonucleotides and deoxyribonucleotides nitrogen-containing substances, which can be formed between the adjacent nucleoside dimer creating new bonds, this action can cause the microorganisms in the water can not be achieved self-replication, so as to achieve the purpose of disinfection. Therefore, the use of ultraviolet light to disinfect water is convenient and fast. But its disinfection effect is influenced by many factors, after water disinfection should also make the necessary pretreatment. Advantages of using UV disinfection technology more prominent, especially in the case of a small amount of water can fully play to their strengths, which uses low doses in a short period of time to be able to kill bacteria in the water. UV disinfection equipment is relatively easy to install, and its management and operation are very convenient, but more importantly is the use of ultraviolet water treatment is a physical process, without adding new substances to the water, the water after disinfection does not produce toxic the product side effects. The ability of the virus itself is very weak resistance to ultraviolet light, protecting the host if the virus after the adoption would enhance the ability of the virus resistant to ultraviolet rays, and therefore, the use of ultraviolet light to disinfect water pretreatment should not be able to ensure continuity of sterilization Effect.

Fixed upper and lower flanges, the operation carefully, because the distillation column is a pressure vessel; f, replace the throttle plate, being careful premade mark recovery; g, according to the above principles and methods for cleaning condenser cooling water for cleaning.

I produced Drinking Water UV Sterilizer (hereinafter referred to as ultraviolet disinfection) working principle is to use a wavelength of 225nm-275nm UV role in the killing of microorganisms for the water to be purified. When water flows through the disinfection by ultraviolet light, water, bacteria is killed. First, the product features: 1, ultraviolet disinfection sterilization speed, the effect does not change the water physical and chemical properties do not increase the water taste and odor, no carcinogenic chloroform, once installed, easy to operate, easy management. 2, UV sterilizer cylinder using high-quality food grade stainless steel plate processing, service life is 5-10 times that of aluminum products, high pressure, metal ion contamination. 3, UV germicidal lamp selection of the identified state health departments, epidemic prevention departments of professional products, low-voltage 30w, main lines 235.7nm, the highest rate of this wavelength ultraviolet disinfection, more than 98%, and low power consumption, continuous service life of up to 3,000 hour or more. 4, and electrical control box with one design, appearance, save space. Second, the scope: Applicable to rivers, Wu Tong and well water of small water systems, especially with high water tank and storage tank with a water supply system. Installation of ultraviolet disinfection in the high water tank and storage tank at the exit can effectively solve the secondary pollution caused by harmful bacteria exceeded due to the problems, but also for food, beverage, brewery industries and the swimming pool water disinfection. Third, installation, commissioning: 1, ultraviolet disinfection should be installed horizontally (prohibited vertical installation). 2, UV sterilizer cylinder shall withstand the external pressure. 3, UV sterilizer should be installed at the outlet of the tank or water tower, Flow volume, high pressure or excessive network while installed on the user's trunk closer (branch) is better. 4, extending from both ends of the UV sterilizer outward, should be left ≥1 ≥0.4 m m space, in order to replace the lamp, UV sterilizer should remain 0.6 meters barrier-free space between the front control panel for easy maintenance . 5, regardless of choice of one or more UV sterilizer in parallel, shall install a bypass pipe and valve to facilitate maintenance. 6, reasonable choice installation location, pay attention to the electronic control part of the water and moisture. 7, according to the nameplate voltage, the power to select electrical outlet, wire or connector strips. 8, quartz glass tube and the UV lamp is a valuable fragile items, transportation, installation, use should be avoided bump.

Feature 1. Quickly and effectively kill all bacteria, viruses and other microorganisms; 2. By photolysis, can effectively degrade chloride in water; 3. Simple operation, easy maintenance; 4. Small footprint, processing large amount of water; 5. Pollution, strong environmental protection, does not produce toxic side effects; 6. Low investment costs, low operating costs, easy installation; 7. The use of optics designed a unique inner wall of the treatment process, so that the cavity to maximize the use of ultraviolet light, so that the sterilization effect is doubled Terms and Conditions 1, UV sterilizer non-frequent start, especially in a short time, to ensure that the UV lamp life. 2, regular cleaning of UV sterilizer: according to water quality, UV lamp and quartz glass tube needs to be cleaned regularly with alcohol cotton ball or gauze wipe the lamp, the quartz glass tube to remove dirt and wipe, so as not to affect the UV transmission, affecting the sterilization effect. 3, replace the lamp, first unplug the lamp power, out of the tube, and then wipe the new lamp carefully inserted into the sterilizer, installed seals, check for water leakage, then plug the power . Be careful not to touch the new lamp with your fingers quartz glass, otherwise it will stain affect the sterilization effect. 4, prevention of UV radiation: UV on bacteria have a strong lethal to humans also have some damage, start light disinfection, should avoid direct exposure to the human body, when necessary, use protective glasses, not directly with the eye front light, lest Eye burns. We also need to bring attention to the UV sterilizer of drinking water treatment bacteria have a strong lethal to humans also have some damage, the body most vulnerable parts of the cornea of the eye, and therefore are not available at all times eye contact with UV disinfection lit lamp, to avoid injury, if you must look at ultraviolet light disinfection, the application of ordinary glass (glasses) or translucent plastic sheet, as a protective mask. Do not try to misuse of quartz glass, because ordinary glass almost completely unable to ultraviolet light is transmitted. Once injured, do not panic, facial burns, skin off a few days later, and heal. Eye injury will be red, tearing, stinging, about three or four days to heal. In any case, confronted with UV rays, it is recommended immediately to the doctor for treatment.
