WASTEWATER DISINFECTION RESOURCES

WASTEWATER DISINFECTION SOLUTIONS

  • TrojanUV3000Plus — Wastewater Disinfection System

    The TrojanUV3000Plus® is one of the reasons why UV treatment is now a favored technology in wastewater treatment. Often touted as a flagship UV system, it has demonstrated effective and reliable performance around the world. In fact, over 2,000 municipalities rely on it to disinfect over 30 billion gallons of wastewater every day.

  • High Speed CSO Filtration System

    As measures of improving the combined sewer system, this high rate filtration system filters the rain water, which flowed directly to the river before, by using our original filter media. This new treatment system can be installed in the existed facilities and supplies stable filtrations for rainfall flow fluctuation.

  • The VLR® System for TrueSND™ Biological Treatment

    VLR® Systems from Evoqua utilize a vertical loop based design with looped reactors in series that allows DO stratification. As such, it is suited for simultaneous nitrification/denitrification; biological phosphorus removal and storm water treatment..

  • OSEC®L On-Site Hypochlorite Generation System

    The OSEC® L system is a fully automated and pre-packaged low-capacity On-Site Hypochlorite generating system that creates <1% sodium hypochlorite solution based on disposable bipolar electrode technology.

  • UniSystem® Package Wastewater Treatment Plant

    The standard UniSystem package plant is a rectangular tank consisting of an aeration chamber, hopper bottom clarifier, sludge holding tank, and chlorine disinfection chamber. Aeration Industries can supply painted carbon steel tankage or all of the internals and ancillary equipment for installation in concrete tanks. Treatment modules can be easily added to the design of the UniSystem depending on influent characteristics and effluent requirements. Treatment module options include a comminutor, flow equalization, denitrification equipment, filters, a membrane bioreactor, UV disinfection, post aeration, and phosphorus removal equipment.

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.
