(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.
