WASTEWATER DISINFECTION RESOURCES

WASTEWATER DISINFECTION SOLUTIONS

  • Wallace & Tiernan® Chlorine Gas Feed Systems

    About 100 years ago, Charles F. Wallace and Martin F. Tiernan installed the first chlorinator in New York, and since, chlorine gas has been the predominant chemical for the disinfection of water.

  • 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.

  • 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.

  • TrojanUVFlex – Drinking Water Disinfection System

    The TrojanUVFlex is designed with features to make installation and operation simpler, faster, and more cost-effective than ever before. Built on the proven TrojanUV Solo Lamp Technology platform, TrojanUVFlex allows for energy-efficient high-intensity delivery of UV light in an extremely compact footprint.

  • CHEM-FEED® Wall Mount Duplex Skid System CFWS-2

    The  CHEM-FEED® Wall Mount Duplex Skid System is designed to be mounted on a wall freeing up valuable floor space. Available in a simplex and duplex chemical feed pump configurations. Pipe material options include PVC, CPVC, PVDF, and Chem Proline® (PE).

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.
