WASTEWATER DISINFECTION RESOURCES

WASTEWATER DISINFECTION SOLUTIONS

  • GENCLEAN-AQ

    GENCLEAN™ AQ is an NSG 60 certified specialized advanced oxidation treatment specially developed for process water disinfection and wastewater treatment for food & beverage processing companies and fish farms.

  • ESTâ„¢ Wet Odor Control Scrubber Systems

    De Nora Water Technologies - EST WET ODOR CONTROL SCRUBBERS are engineered to treat malodorous gases emanating from municipal and industrial wastewater treatment facilities.

  • 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.

  • 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.

  • Emergency Chlorine Scrubbers

    IMS Wet Emergency Chlorine Scrubber Systems are designed to contain and treat accidental releases of chlorine gas. Systems are offered to treat up to 3 tons of chlorine gas. The IMS wet emergency chlorine scrubber is a three-stage single-pass chemical absorption system with very high efficiency horizontal packed bed sections. An induced draft fan pulls the chlorine gas through the scrubber, where it contacts a recirculation caustic solution. The scrubber system is factory pre-assembled, complete with induced draft fan, recirculation pump, instrumentation and controls.

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.
