WASTEWATER DISINFECTION RESOURCES

WASTEWATER DISINFECTION SOLUTIONS

  • Ozone Disinfection: 499AOZ Dissolved Ozone Sensor

    The 499AOZ sensor is intended for the continuous determination of dissolved ozone. The primary application is ozonation basins in municipal water filter plants. Ozone is also used as a disinfectant in bottling and food processing plants.

  • GWT Zeroturb Bio-Organic Liquid Flocculant

    GWT advanced ZeoTurb™ is a unique advanced bio-organic liquid flocculant.

  • 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).

  • Wallace & Tiernan® Analyzers and Controllers

    Wallace & Tiernan MFC analyzer/controller offers a broad combination of drinking water analysis and disinfection/chemical control in a single unit.The MFC analyzer/controller offers an easy, software selectable range of control modes from flow proportional, residual control only, compound loop and set point trim enabling precise control of a chlorinator or metering pump to maintain the desired level of disinfection and water quality.

  • 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.

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.
