WASTEWATER DISINFECTION RESOURCES

WASTEWATER DISINFECTION SOLUTIONS

  • PAX Mixers

    The PAX Mixer design is based on rigorous scientific analysis of fluid mechanical principles to achieve rapid disinfectant blend time. The mixers are designed for energy efficiency and engineered for ease of installation.

  • UVAS Plus sc UV Sensor

    Continuous UV 254 Absorbance/Transmittance measurements can be used to protect plant treatment processes from high organic loads. Analysis range of 50 mm probe is 0.01 - 60 m-1. Use for the following applications: protection of treatment plants from industrial dischargers, monitoring shock loads from internal plant processes, control of activated sludge processes, control methanol feed in BNR based on organic loading, final effluent monitoring and monitoring efficiency of UV disinfection processes.

  • 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.

  • UV Technology Offers Solution For Emerging Water Crisis

    Many are turning to UV as an effective barrier to enable the reuse of wastewater, for indirect reuse, and aquifer recharge.

  • GS1440 Sensor H2S

    Water or air, measure H2S where it matters – right at the source.

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.
