ETS-UV for Wastewater Treatment BrochureSource: Engineered Treatment Systems / ETS-UV
Municipal wastewater was originally disinfected using chlorine. As awareness grew regarding the potential for carcinogenicity, UV light gradually replaced the use of chemicals. The earliest UV systems utilized racks of lamps immersed into an open channel. These open, gravity flow channels suffer from many disadvantages; poor hydraulic mixing, very large footprint, expensive to build, and are vulnerable to fluctuations in flowrate.
