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.

  • Sanitaire Taron™ Activated Sludge Filter

    Applying Sanitaire’s wastewater treatment expertise, the innovative Taron Activated Sludge Filter can help plants meet discharge limits and expand capacity in a compact footprint. The Taron filter provides reliable solids reduction from high MLSS concentrations.

  • 3-Way Valve

    The 3-Way Valve is available in 4”, 6” and 8” sizes and is available as a stand-alone valve or as part of a Vaughan submersible or vertical wet-well Chopper Pump. The valve is a non-plug design using a rotatable CD-4MCu valve disc to allow discharge out of either of the top ports.

  • Constant Chlor® MC5 Feeder

    The Constant Chlor® MC5 Feeder system provides reliable chlorine solutions for water treatment plants, waste water plants and water reclamation facilities. The Constant Chlor® system consistently delivers liquid available chlorine for disinfection applications that kills bacteria, controls algae and removes organic contaminants. The feeders use EPA registered Constant Chlor® Briquettes that work in conjunction with the feeder to produce a fresh concentrated liquid chlorine solution for clean, clear, sanitized water. Treats facilities with up to 10 MGD ranging from a minimum of 5 lbs a day available chlorine to 83 lbs a day available chlorine.

  • ClorTec® DN On-Site Sodium Hypochlorite Generators

    The latest generation of brine electrochlorination technology, the ClorTec DN range, offers simple operation and maintenance as well as unrivalled safety advantages.

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.
