WASTEWATER TREATEMENT

wastewater treatment plant

In The United States alone there are over 22,500 Wastewater Treatment Plants that must adhere to stringent guidelines monitored by State and Government agencies to ensure water is safe for recycled use or to safely discharge into our rivers, streams and waterways. Disinfection is considered to be the primary mechanism for the inactivation/destruction of pathogenic organisms to prevent the spread of waterborne diseases to downstream users and the environment. It is important that wastewater be adequately treated prior to disinfection in order for any disinfectant to be effective.

Approximately half of today’s plants utilize an Ultraviolet (UV) disinfection system that transfers electromagnetic energy from a mercury arc lamp to an organism's genetic material (DNA and RNA). When UV radiation penetrates the cell wall of an organism, it destroys the cell's ability to reproduce. UVC, which peaks in the 254 nanometer range, is key to the destruction of microorganisms and bacteria. Specific materials used in manufacturing the UV lamps also allow energy production in the 185 namometer range to produce Ozone (O3).
