Ultraviolet Disinfection Technology-Treatment Plan for Drinking Water

1.Characteristics of UV Disinfection
Compared with other disinfection methods, UV disinfection has the following characteristics:
1) It can disinfect many kinds of microorganisms. It is more effective for those microorganisms, such as pathogenic protozoa, bacterium, virus.
2) It has no secondary pollution, because there is no usage of chemicals, it does not produce secondary pollutants, in water body or to the surrounding environment.
3) The operation and maintenance are safe and reliable, no demand of storage, carriage and usage of any toxic, corrosive chemicals.
4) It has the lowest operating costs, among all disinfection methods.
5) It only needs small area, due to that ultraviolet disinfection contact time is very short (1-2 seconds). The construction investment is very low.
  
2. UV Disinfection Technology Applications Range 
Municipal wastewater, water reuse, municipal drinking water; 
Industrial process water of food, beverage, semiconductor and pharmaceutical engineering; 
Aquaculture, commercial water and small civilian water disinfection and environmental chemical contaminants treatment;

3. Why Choose UV to Disinfect Drinking Water
A. Multiple barrier disinfection strategy
The traditional single chlorine disinfection method has been unable to provide comprehensive security barrier. In China National Standard GB5749-2006, it adds the water quality standards from 35 to 106 items, especially adding Cryptosporidium and Giardia. These two items are resistant of Chlorine. UV is the most efficient and best cost performance method to inactivate the two items, which is proven. In addition, UV can expand the control coverage of microbial, reducing the dosage of chemical disinfectants and by-product. It also can guarantee the stability of pipe network biological stability. When other disinfection process fault, UV disinfection can be safe security and emergency. 
B. Obvious economic benefits
Compared with O3 and membranes separation technology, UV technology has lowest investment and operation cost.

4. Why use medium pressure UV lamp to disinfect drinking water
Compared with low pressure (high output) lamp, it has some advantages as follows:
(1).Medium pressure UV lamp has larger wavelength range, high UV output intensity, and good inactivation effect to all known bacteria.
(2).Medium pressure UV lamp can avoid microbial resurrection.
(3).The water temperature has no influence to medium pressure lamp output.
(4).Compact design and small area demand are particularly suitable for 
 old factory to transformation, with space limitation.
(5).One medium pressure lamp’s UV output intensity output is 10 to 100 times than low pressure one, with less lamp quantity and lower maintenance cost.

Sentinel® UV Disinfection system
Systematic review
SENTINEL® UV Disinfection system is a big technology breakthrough in drinking water disinfection field, since it applied in1999.
