Stainless Steel Open Channel Ultraviolet Disinfection System for Waste Water Treatment
Introduction
Open channel UV systems are mainly used at the municipal water/wastewater treatment plants for water recycling and effluent disinfection to ensure a better level of environmental protection.
UV disinfection is an effective and environmentally friendly alternative to the conventional chlorine effluent disinfection. Nowadays more than 15% of 2000 waste water treatment plants in North America have chosen the UV as the primary disinfection method. UV disinfection has proved its safety, reliability, efficiency, and economical characteristics over the years.
Open channel UV sterilizers have been used for waste water, sewage water disinfection in order to achieve a lower environment pollution drainage.
How UV Disinfection Works
Unlike chemical approaches to water disinfection, UV provides rapid, effective inactivation of microorganisms through a physical process. When bacteria, viruses and protozoa are exposed to the germicidal wavelengths of UV light, they are rendered incapable of reproducing and infecting. UV light has demonstrated efficacy against pathogenic organisms, including those responsible for cholera, polio, typhoid, hepatitis and other bacterial, viral and parasitic diseases. In addition, UV light (either alone or in conjunction with hydrogen peroxide) can destroy chemical contaminants such as pesticides, industrial solvents, and pharmaceuticals through a process called UV-oxidation.
