WASTEWATER DISINFECTION RESOURCES

WASTEWATER DISINFECTION SOLUTIONS

  • WWETCO FlexFilter™

    The WWETCO FlexFilter™ from WesTech uses compressible media to provide an efficient new solution for CSO, Primary Treatment, Tertiary Treatment and Industrial Water Pretreatment. The FlexFilter™ is a simple gravity system with a robust design requiring no moving parts. The combination of tapered media compression, porosity gradient within the media bed and a low flow backwash system make the WWETCO FlexFilter™ one of the most versatile and efficient filters on the market.

  • Emergency Chlorine Scrubbers

    IMS Wet Emergency Chlorine Scrubber Systems are designed to contain and treat accidental releases of chlorine gas. Systems are offered to treat up to 3 tons of chlorine gas. The IMS wet emergency chlorine scrubber is a three-stage single-pass chemical absorption system with very high efficiency horizontal packed bed sections. An induced draft fan pulls the chlorine gas through the scrubber, where it contacts a recirculation caustic solution. The scrubber system is factory pre-assembled, complete with induced draft fan, recirculation pump, instrumentation and controls.

  • NeoTech D338™

    The NeoTech D338™ is specially designed to disinfect water and is an essential component in advanced oxidation processes.

  • The VLR® System for TrueSND™ Biological Treatment

    VLR® Systems from Evoqua utilize a vertical loop based design with looped reactors in series that allows DO stratification. As such, it is suited for simultaneous nitrification/denitrification; biological phosphorus removal and storm water treatment..

  • EST™ Wet Odor Control Scrubber Systems

    De Nora Water Technologies - EST WET ODOR CONTROL SCRUBBERS are engineered to treat malodorous gases emanating from municipal and industrial wastewater treatment facilities.

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.
