WASTEWATER DISINFECTION SOLUTIONS

  • Model 4180 All Vacuum Chemical Feeder

    The JCS Industries Model 4180 All Vacuum Chemical Feeder is for operations that require high efficiency, accuracy, control and safety. The Model 4180 will feed chlorine dioxide solution used in municipal and industrial water treatment systems.

  • 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.

  • Trident® HS Package Water Treatment Plant

    The Trident HS package water treatment plant provides multi-barrier protection for difficult-to-treat surface water, groundwater, industrial process water, and tertiary wastewater. The multi-barrier design of the Trident HS, which consists of packaged high-rate settling, adorption clarification, mixed media filtration and optional UV disinfection, is the latest improvement of the original Trident system.

  • Pipeline Flash Reactor Plus (PFR+)

    Today’s high dosage ozone systems, such as those required by water reuse projects, place extraordinary energy and mixing demands on ozone mass transfer. Mazzei utilized multiphase computational fluid dynamics (CFD) analyses to develop the new PFR+ to address these challenges.

  • 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.

WASTEWATER DISINFECTION VIDEOS

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.
