WASTEWATER DISINFECTION SOLUTIONS

  • Comparison Of Ultra Low Range Total Chlorine Residual Limits Of Detection And Quantitation Across The Water Industry

    Limits of Detection and Quantitation are key to understanding analytical instrumentation capabilities, especially when non-optimal process control can lead to damage of sensitive equipment due to insufficiently accurate readings.

  • RapiSand™ Ballasted Flocculation System

    The WesTech RapiSand™ ballasted flocculation system is a high-rate clarification process combining rapid mixing and multi-stage flocculation, followed by sedimentation. RapiSand™ sedimentation is extremely fast and can be applied in a wide variety of suspended solids removal applications.

  • Model 420-Cylinder Mounted Regulator

    The JCS Industries Model 420-Cylinder Mounted Regulator is designed for years of safe and reliable service.

  • Small Tank Mixing

    Small tank mixing is a lower cost, simplified Rotamix system, using a Chopper Pump and external-mount nozzle assemblies. The external-mount nozzles are sandwiched between 6" ANSI flanges and provide fixed discharge angles off the tank wall.

  • Oxelia™

    Xylem’s Leopold Oxelia is an ozone-enhanced biologically active filtration system and multi-barrier solution for municipal wastewater treatment. The Leopold Oxelia system combines ozone, filtration and analytical instrumentation to deliver optimal wastewater treatment for water reuse and discharge into sensitive waters.

As aquatic invasive species continue to overwhelm hydropower, industrial, and municipal systems worldwide, this webinar explores why traditional filtration and chemicals are falling short—and how a dual-barrier UV approach is emerging as a proven, chemical-free alternative backed by global field results.

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.
