UV-C rays represent today one of the best methods for the disinfection of water: thanks to the physical principle on which their germicidal power is based, they only act where it is necessary, in the full respect of the most exacting rules of environmental protection.
Ultraviolet radiation can be used as a pretreatment or polishing step to sterilize and disinfect water. UV systems are typically used to pre-treat a water supply that is considered biologically unsafe (lake or sea water, well water, etc). The UV disinfection process is a non-chemical method for destroying microorganisms by altering their genetic material, and rendering them unable to reproduce.
There are several advantages of using UV rather than a chemical disinfection solution (such as chlorination):
1. No known toxic or significant nontoxic byproducts
2. No danger of overdosing
3. Does not require storage of hazardous material
4. Adds no smell to the final water product
5. Requires very little contact time
Applications include private wells, camp grounds, hotels, bottlers, aquaculture, hospitals, food, cottages, restaurants, breweries, water systems, laboratories, marine, pharmaceutical, dairies and many other applications.
