WASTEWATER DISINFECTION SOLUTIONS

  • 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.

  • Chlorine Measurement In Wastewater And Regulated Discharge Requirements

    Homes, industry, schools, and businesses all generate sanitary waste, or sewage. Sewage treatment is a multistage process that cleans up wastewater before discharge or reuse. In the final step of the treatment, disinfectants are added to kill disease-causing organisms. Common disinfectants are chlorine gas and sodium hypochlorite. Chlorine dosage levels are designed to leave almost no residual in the wastewater after treatment

  • Next Gen Capital Controls® Chlorinators

    The unique compact design incorporates the best existing Capital Controls® technology with exciting new features. With just three models ranging from 10-10,000 lbs/day capacity, each chlorinator is available with automatic or manual feed and a 10” flowmeter for an easier read. Sonic operation on the 4100 model eliminates the need for a differential pressure regulator. On all automatic models, an additional controller isn’t needed, reducing components – and costs. 

  • What Is Genclean Advanced Oxidation Disinfection Solution And What Is It Used For?

    A non-toxic, advanced oxidation (AOP) formula of minerals chelated with oxygen and stabilized in an aqueous water solution. It is a viable option in industries and applications requiring a solution to challenging situations where high level effective sanitization and oxidation is required. Read more to learn how the Genclean advanced oxidation treatment solutions can be used in different applications.

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.
