In the same way that exposure to ultraviolet (UV) light from the sun creates a skin cancer risk,
artificially generated UV light can be used to protect drinking water from dangerous microscopic organisms.
Demand for UV water treatment equipment is driven primarily by existing environmental and drinking water quality regulations, increased re-use of treated wastewater, and concern over chlorine’s toxicity.
Currently thousands of water and wastewater treatment plants around the world use mercury vapour lamp UV technology as part of systems designed to protect human health and the environment from biological pathogens and chemical pollutants.
The majority of UV water treatment systems are used to inactivate pathogenic micro-organisms. The Advanced Oxidation Process (AOP) involves injecting oxidizing chemicals (typically hydrogen peroxide) into treatment water just upstream of the UV chamber to provide chemical treatment of organic pollutants. Both these UV water treatment methods are reliable, but involve high energy cost, high lamp replacement cost, and difficult, expensive lamp cleaning procedures.Contact us See Applications
