WASTEWATER DISINFECTION SOLUTIONS

  • TurboCoag Treatment For Industrial Wastewater

    TurboCoag is an innovative Tesla pump with patented rotating electrodes. These electrodes are energized with an electrical potential that causes current to flow through the fluid to be treated, dissolving the anodes into reactive anions into the water which binds to the contaminants, forming a strong floc. 

  • GWT Specialized Electrocoagulation System

    GWT electrocoagulation (EC) technology has become a valuable solution in the treatment of water and wastewater due to its ability to remove contaminants that are generally more difficult to remove by filtration or chemical treatment systems, such as emulsified oil, silica, total petroleum hydrocarbons, refractory organics, suspended solids, and heavy metals.

  • Process Monitoring And Control For Increased Productivity And Efficiency

    The Littleton/Englewood wastewater treatment plant, Colorado, put in place processes to effectively monitor the levels of ammonia in their wastewater treatment.

  • 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.
