UV-C Water Disinfection
Sources of naturally clean water are becoming increasingly scarce, making it one of the world’s most critical resources. More and more communities and companies have to recycle water.
Climate change also means that they rely more and more on ground aquifer or river sourced water. This raw water is only as good as the chemical or biological nature of the contaminants that flow into the river from the ground’s surface water run-off; or penetrate through the ground, into the water table. Once these contaminants are in the water table, they are then dispersed into the broader aquifer from which we abstract our drinking water source.
Without proper disinfection, water from watercourses, whether from above or below ground, is likely to contain dangerous waterborne pathogens, including cryptosporidium and giardia.
Germicidal Ultraviolet (UVC) water disinfection
Disinfection using Germicidal Ultraviolet (UVC) light is a decades’ proven, chemically-free, safe, and sustainable method for creating safe drinking water by destroying water containing viruses, bacteria, moulds, yeats, protozoa, spores, algae and other micro-organisms.
UVC flow reactors are installed in the treatment works and/or in water pipelines. They are designed for the appropriate liquid flow rates, target pathogens (local or new pathogens may prevail), the water temperature and disinfection level, all of which, affect UVC dosage. UVC is particularly suitable for disinfection of cooling towers, hot and cold-water systems and drinking water, whether bore-hole or river abstracted water for drinking, or processing.
In contrast, for hot water systems, UVC is used to combat biofilms (a thick layer of harmful microbes) on immersion heaters and so one needs effective water treatment in the tank. Clearly, the other main benefit of in-tank systems, is eradicating the deadly pathogen, Legionella. If the water quality is very poor, our UVC emitters, can provide water treatment for industrial process water too.
