Danaher Group is one of the global top 500 enterprises listed in the U.S. Fortune magazine. Beside the the headquarters in Canada, It still has subsidiaries or branches in the United States, Netherlands, United Kingdom, Norway, Germany, Spain, Sweden and China.The largest three of the world's cities use ultraviolet disinfection in waterworks, : Seattle of United States uses 68 tons / day; Rotterdam of Netherlands waterworks uses 470,000 tons / day, Tianjin TEDA of China's first waterworks uses 220,000 tons / day; The Asia largest sewage treatment plant in white dragon port in shanghai uses 260 tons / day, The UV disinfection design specifications for national wastewater prepared by our participation. |
  Won the title of 2008 National Top Ten municipal wastewater treatment plant equipment suppliers;Overall Ranked first of water user satisfaction in the water industry in 2008-2009 disinfection equipment class :Won the first brand of water industrial disinfection equipment survey in 2009 Water industry in China.2009 Stockholm Industry Water Award --- Won the Nobel Prize in water |
This Drinking water system designed for economy means to remove more than 99.99% of bacteria, viruses and parasites use in a single region or an entire house. Implementation of this process without adding any harmful chemicals to the water which you drink,and don’t like other methods of disinfection caused with toxic byproducts which is carcinogenic, teratogenic and caused the genic mutation.But uses UV for water treatment is the most natural and ecological methods. Realization of all is just a spent very little cost everyday!
"Sterilight Cobalt's" new type of home ultraviolet disinfection system with high UV output, Axial flow characteristics, these technologies make the device easy to install , just need minimal installation space requirements in the market. Customers can choose according to their own needs 10 "or 20" high-speed filter and match different filter media. We can provide a LED light displays remaining lamp life and controller which total running time and standard type "Cobalt-BASIC “system ,It also can provide one kind of" Cobalt-PLUS "type high configuration system, the system additional monitoring wavelength of 254 nm UV monitoring results by the discrete signal output of the sensor, and can choose to add a solenoid valve, to achieve the automatic closing function. Whether you have any special requirements of the application, Our new Cobalt DWS system is able to provide solution for you
"Sterilight Cobalt's" new type home ultraviolet disinfection system with high UV output and axial flow characteristics, these technologies make the device easy to install and just minimal installation space requirements for equipment.

System advantages of UV water purification:
1.Fast effect, good effects on disinfect (0.5s-5s, 99.99%) 2.UV does not produce toxic by-products; 3.Safety, no chemicals added 4.Maintenance is simple and convenient 5.UV relative to other process has investment advantage (including civil engineering, transportation, storage, and regulations, personnel, etc.); 6.UV running costs is about 1/5 of ozone, 1/10 of the membrane filter; 7.Effective inactivation of Cryptosporidium and Giardia lamblia; 8.UV disinfection be widely accepted by authority at home and abroad; 9.Don’t change the color, odor and taste of the water. |
 UV light is a part of the electromagnetic spectrum, the wavelength of between 100 to 400nm, the bactericidal effect of the wavelength is located within the spectral range of 200 to300 nm.ultraviolet light is generally divided into the following: UV-A (Long-band ultraviolet light): 315-400 nm UV-B (in-band ultraviolet): 280-315 nm UV-C (short wave UV): 200-280 nm vacuum UV: 100-200 nm  UV disinfection principle In the case of the normal amount of the disinfectant has not been found. |
 The UV disinfection is through the the photochemical action to break the microbial genetic material - the form of the nucleic acid, prevent microbial replication and renewable, Reach the disinfection purposes. The nucleic acid within the cell is divided into ribonucleic acid (RNA) and deoxyribonucleic acid (DNA), in the absorption of sufficient UV energy may cause the adjacent nucleosides to form a new dimeric conjugates - usually is thymine. So that the microbes can not be copied and regenerated , so that lead to death. |

1、Suspended Solids: sediment, rust, visible objects; The tap water must through rigorous process before leave the factory, the latter three appeared highly unlikely, the the secondary pollution of tap water mainly from aging municipal water supply network. 
E. coli： In 2000,the flash floods in Ontario, Canada Volcker Dayton town caused drinking water by infection the most serious E. coli infection in Canadian history, causing more than 5,000 people infected, seven people were killed, infected with E. coli,The symptoms usually infections occur in 5-7 days. |
The purposes of Water disinfection:Disinfection defined: the inactivation of the pathogenic microorganisms of the waters (pathogenic organisms), so that to be reduced to an acceptable degree.

Cryptosporidium disease outbreaks in abroad It has six continents and 74 countries now, at least 300 districts had found the cryptosporidiosis. About 1% -2% of diarrhea patients detected Cryptosporidium in Europe, 0.6% -4.3% in North America, 3% -4% in Asia, Australia, Africa, and Central and South America up to 10% .The survey shows that in the United States, most tap water contain small amount of Cryptosporidium, and at least six case confirmed the cryptosporidiosis caused by the drinking water till now. The most serious is that the water supply in Milwaukee, Wisconsin, United States, April 1993 which contain Cryptosporidium. Caused 150million people suffered a great shock.
