  • The VLR® System for TrueSND™ Biological Treatment

    VLR® Systems from Evoqua utilize a vertical loop based design with looped reactors in series that allows DO stratification. As such, it is suited for simultaneous nitrification/denitrification; biological phosphorus removal and storm water treatment..

  • Model 4200-LC Automatic Gas Feeder Controller

    The JCS Industries Model 4200-LC Automatic Gas Feed Controller feeds gaseous chemicals commonly used for water and wastewater disinfection accurately, reliably and safely.

  • 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.

  • WWETCO FlexFilter™

    The WWETCO FlexFilter™ from WesTech uses compressible media to provide an efficient new solution for CSO, Primary Treatment, Tertiary Treatment and Industrial Water Pretreatment. The FlexFilter™ is a simple gravity system with a robust design requiring no moving parts. The combination of tapered media compression, porosity gradient within the media bed and a low flow backwash system make the WWETCO FlexFilter™ one of the most versatile and efficient filters on the market.

  • SuperDisc™ Disc Filter

    WesTech’s SuperDisc™ Disc Filter from Nordic Water is a Title 22 approved inside-out disc filter.The SuperDisc provides easy access for maintenance and has an efficient high pressure cleaning system. The small footprint and low head required for the filter provides an excellent option for tertiary retrofits, such as travelling bridge sand filters. The SuperDisc can produce reuse-quality effluent and total effluent phosphorus concentrations of less than 0.1 mg/L. Other applications include primary and secondary treatment, as well as a wide range of industrial applications. The SuperDisc filter is available as a freestanding unit with filter discs contained in a stainless steel tank and a version for installation in a concrete basin.

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.
