WASTEWATER DISINFECTION SOLUTIONS

  • NeoTech D328™

    The NeoTech D328™ is specially designed to disinfect water and is an essential component in advanced oxidation processes.

  • BG Plant Pro

    A 1 gallon, fully automated bench-scale reactor that runs real treatment cycles on-site. Not sampling, not simulation.

  • 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.

  • ETS-UV™ For Wastewater Treatment

    Many municipalities had adopted ultraviolet (UV) disinfection treatment over chemical based disinfection.  UV disinfection is efficient, low cost and an environmentally friendly way to disinfect water.  The process is safer for operators and the community; UV is a chemical free process that adds nothing to the water but light.  Read more about how the UV disinfection works.  Unlike chlorine, UV disinfection is able to inactivate pathogens such as Giardia and Cryptosporidium.  Discharged wastewater with these pathogens becomes dangerous drinking and recreational water for downstream communities.    

  • 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.

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.
