WASTEWATER DISINFECTION RESOURCES

WASTEWATER DISINFECTION SOLUTIONS

  • ROMAG™ CSO Screen

    The ROMAG RSW CSO Screen, fitted between the discharge culvert and the relief sewer, reliably retains all visible solids during peak events.

  • SuperDisc™ Disc Filter

    WesTech’s SuperDisc™ Disc Filter from Nordic Water is a Title 22 approved inside-out disc filter.The SuperDisc provides easy access for maintenance and has an efficient high pressure cleaning system. The small footprint and low head required for the filter provides an excellent option for tertiary retrofits, such as travelling bridge sand filters. The SuperDisc can produce reuse-quality effluent and total effluent phosphorus concentrations of less than 0.1 mg/L. Other applications include primary and secondary treatment, as well as a wide range of industrial applications. The SuperDisc filter is available as a freestanding unit with filter discs contained in a stainless steel tank and a version for installation in a concrete basin.

  • 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.

WASTEWATER DISINFECTION VIDEOS

As aquatic invasive species continue to overwhelm hydropower, industrial, and municipal systems worldwide, this webinar explores why traditional filtration and chemicals are falling short—and how a dual-barrier UV approach is emerging as a proven, chemical-free alternative backed by global field results.

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.
