WASTEWATER DISINFECTION RESOURCES

WASTEWATER DISINFECTION SOLUTIONS

  • 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.

  • Pipeline Flash Reactors for Mixing & Contacting

    Pipeline Flash Reactors (PFRs or spool pieces) utilize high velocity mixing to transfer ozone or oxygen-enriched sidestreams into bulk water flow, all within a compact footprint. With a PFR, ozone or oxygen mass transfer occurs in the pipeline within seconds, eliminating the need for additional tanks or basins.

  • Wallace & Tiernan® Disinfection

    Evoqua Water Technologies is the premier provider of total disinfection and chemical dosing solutions. Our extensive portfolio, which includes the trusted Wallace & Tiernan product line, is designed to meet your most rigorous demands in virtually any water application and give you access to both the latest advances and widest range of proven technologies.

  • GWT Specialized Electrocoagulation System

    GWT electrocoagulation (EC) technology has become a valuable solution in the treatment of water and wastewater due to its ability to remove contaminants that are generally more difficult to remove by filtration or chemical treatment systems, such as emulsified oil, silica, total petroleum hydrocarbons, refractory organics, suspended solids, and heavy metals.

  • Model 420-Cylinder Mounted Regulator

    The JCS Industries Model 420-Cylinder Mounted Regulator is designed for years of safe and reliable service.

In this episode of The Water Online Show, host Angela Godwin speaks with Scott Bindner of Trojan Technologies at the AWWA ACE event in Denver. Bindner introduces Trojan’s latest innovation: a compact, mobile demonstration unit for UV advanced oxidation processes (UV AOP).

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.
