WASTEWATER DISINFECTION SOLUTIONS

  • Constant Chlor® Rapid Rate Feeder Fast-Acting CSO Disinfection System

    The Constant Chlor® Rapid Rate Feeder is a highly-customizable large scale CSO disinfection system for wastewater applications. CSOs may occur after a large rainfall or melt, causing wastewater to exceed the capacity of the system. When used with Constant Chlor® Plus Briquettes, the Rapid Rate feeder is able to quickly disinfect the large volume of wastewater during a CSO event.

  • Oxelia™

    Xylem’s Leopold Oxelia is an ozone-enhanced biologically active filtration system and multi-barrier solution for municipal wastewater treatment. The Leopold Oxelia system combines ozone, filtration and analytical instrumentation to deliver optimal wastewater treatment for water reuse and discharge into sensitive waters.

  • OaSys iCT™: Next-Level Dosage Control For Chemical Disinfection

    When chemical disinfection is used, inherent variability in plant processes (e.g. flow events, plant upsets) can result in inadequate public health protection and risk of permit violation. To avoid these disruptions, WRRFs regularly overdose disinfectant, resulting in excessive cost for disinfectant and quenching chemicals and increasing sensitivity to chemical market conditions (supply disruptions, price increases).

  • SedVac Sediment Removal System

    SedVac’s unique design funnels the sludge and scrapes the floor, resulting in consistent solids removal of 3 percent concentration while wasting less water than traditional pipe systems.

  • TrojanUVFlexAOP – Advanced Oxidation System

    Meeting the demand for clean water has never been more challenging. Communities around the world are facing a growing water stress – an insufficient supply, in terms of water quality or water quantity – and often both. Many are turning to potable reuse and drinking water remediation to meet these demands. The TrojanUVFlex®AOP can be part of the solution. This UV advanced oxidation system destroys a range of chemical contaminants while simultaneously providing final treatment, helping municipalities relying on lower quality water sources to continue producing high-quality potable drinking water.

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.
