Disinfection Alternatives for Water and Wastewater

Ultraviolet Disinfection - Wastewater Disrupts organism reproduction Technology of choice for most WWTPs due to inherent safety advantages, simple operation Won’t work well if WW effluent is “cloudy” or excessive solids •Check effectiveness for industrial uses •Check for fixed film treatment •CSO – too dirty; not a good option

UV vs. Chlorine for Wastewater Disinfection | Treatment ...

Sep 17, 2018·Today, UV disinfection is widely accepted for municipal wastewater disinfection around the world. UV is rapidly growing, given it’s a safe and cost-effective alternative over chemical disinfection. Also, it produces no disinfection byproducts or a chlorine residual, which is harmful to the environment.

“Attainment of the disinfection guidelines can only be achieved by the disinfection process, which, from a disease prevention standpoint, is the most important unit process in the wastewater treatment system.” 3. Disinfection of water and wastewater, primarily by chlorine, has played a large part in the reduction of waterborne diseases.

Wastewater Technology Fact Sheet: Ozone Disinfection

An ozone disinfection system strives for the maximum solubility of ozone in wastewater, as disinfection depends on the transfer of ozone to the wastewater. The amount of ozone that will dissolve in wastewater at a constant temperature is a function of the partial pressure of the gaseous ozone above the water or in the gas feed stream.
