Waste water treatment
Increased attention to environmental protection may cause increasing use of UV disinfection systems instead of chlorination in more than 70% of waste water treatment plants in domestic market, as UV treatment does not produce DBPs (disinfection by-products) at all.
Now various facilities from small automated village sewage treatment plants to large ones apply UV treatment systems, and the application has also diversified, which could mean UV treatment is generally approved as the effective and cost-efficient way of waste water disinfection.
In order to destruct pathogenic microorganisms which exist even after several steps of treatment processes, UV treatment has been suggested as the solution instead of conventional treatments that have their own limits such as insufficient treatment, cost burden, environmental pollution, deterioration of water quality or odor.
UV does not cause odor or DBPs (disinfection by-products) and effectively inactivates several pathogens like Cryptosporidium, Giardia which are highly tolerant to chlorination. UV is used worldwide in millions of drinking water treatment plant as it guarantees stable performance, can minimize chlorine input, is easy to operate, and is not affected by water temperature or pH value.
Food & beverage
The food and beverage industry demands strict quality control such as HACCP (Hazard Analysis Critical Control Point) Program as the products need to be preserved as theirs original tastes and flavors and to be sterilized.
Variety of food and beverage process is equipped with UV disinfection systems as they can sterilize the products without any change in quality and shape. Besides, production equipments and sanitary facilities for production staff also use diverse technology applying UV techniques.
Swimming pool, spa, sauna
Swimming pool, spa and public sauna maintains some level of chlorine in the water for continual disinfection. Feeding chlorine is an effective way of disinfection, but its by-products forms chloramines causing displeasure for bad smell, irritation on eyes or skin, and deterioration of the facilities.
As an alternative solution UV treatment does not produce odor, is highly effective in inactivating pathogens, can reduce the quantity of chlorine feeding so that easily satisfy the visitors there.
Zoos, aquaria and dolphinaria, aquaculture
Zoos and aquaria always have infection or odor problem resulting from their own excrement, secretion, and other leftovers. These facilities often have difficulty removing algae which keep deteriorating the artificial breeding environment e.g.
forming toxin or low level of dissolved oxygen, and might cause mass infection, low breeding coefficient, and underdevelopment.
UV treatment does not affect ecosystem under water or produce toxic by-products, and now a lot of breeding facilities are equipped with UV disinfection systems.
Treating environmental contaminants with UV
Rapid economic development of the humankind has caused environmental pollution and its accumulation has caused serious inconvenience where we live.
UV itself can resolve or oxidize these pollutants, and it can remove carcinogenic substance N-NDMA (N-nitrosodimethylamine), several organisms, odor by adding hydrogen peroxide. Such AOP (advanced oxidation process) technology has developed day by day.
