UV System Provides Safe, Effective Disinfection For Wastewater Treatment Plant On The Hudson River
The communities serviced by the Rensselaer County Sewer District, collectively known as the Albany Pool, have combined sewer systems (CSS) that bring stormwater, sewage and industrial wastewater directly to the wastewater treatment facility. When a storm or snow melt results in exceeded capacity, local waterways become contaminated, resulting in a significant environmental challenge, especially in a community where recreational swimming, boating and fishing are popular in warmer months.
Retrofit Significantly Reduces Backwash Cycle Interval, Duration And Water Use For Georgia Utility

Ozone Plays Critical Disinfection Role At Water Reclamation Plant
The Rio Grande River and the two major aquifers in the El Paso, TX, area had been dried up for decades when El Paso Water Utilities (EPWU) developed the Fred Hervey Water Reclamation Plant, the nation’s first full-scale wastewater reclamation plant to use tertiary treatment to restore wastewater to national and state potable water standards.
Turbidity And T&O Issues Eliminated With Environmentally Friendly Treatment Technologies
The Metropolitan Water District of Salt Lake & Sandy (District) in Draper, UT, integrated a mix of complementary treatment barriers to address specific disinfection, turbidity, and taste and odor (T&O) issues shared by many surface water treatment facilities while also instilling the needed capabilities to adapt to changing regulatory requirements.
The city of Florence, Colorado Water Treatment Plant (WTP), located 75 miles south of Denver, uses blended surface water taken from the city’s southernmost water reservoir.

ABOUT WASTEWATER DISINFECTION
Wastewater disinfection takes place after primary, secondary and sometimes tertiary wastewater treatment. It is typically a final step to remove organisms from the treated water before the effluent is released back into the water system. Disinfection prevents the spread of waterborne diseases by reducing microbes and bacterial numbers to a regulated level.
A variety of physical and chemical methods are used to disinfect wastewater prior to it being released into natural waterways. Historically, the chemical agent of choice for municipal wastewater treatment has been chlorine, due to its disinfecting properties and low cost. However, the rising cost of chlorine and concerns that low chlorine concentrations can still be toxic to fish and other wildlife, has given rise to more physical methods of wastewater disinfection being adopted such as ozonation or ultraviolet (UV) light.
The use of ozone as a disinfection agent has the added benefit of increasing the dissolved oxygen content of the treated wastewater. However, because the ozone has to be generated, ozonation can require prohibitive up-front capital expenditure compared to traditional chlorination. UV disinfection has been growing in popularity as a wastewater disinfection method, in large part because of the life-cycle economics of the equipment and the fact that, like ozone, there is no toxic residual.
