WASTEWATER DISINFECTION RESOURCES

WASTEWATER DISINFECTION SOLUTIONS

  • 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.

  • WEDECO LBX e Series UV System

    WEDECO LBX e UV system is a compact closed vessel UV reactor for drinking water, wastewater, water reuse, and WEDEO’s MiPRO Advanced Oxidation Processes (AOP) applications. Equipped with WEDECO’s low-pressure, high output amalgam ECORAY® UV lamps and OptiDose sensor based control, the LBXe provides the highest operating efficiency with low life-cycle costs. Additionally, the LBXe reactor’s extensive validation envelope ensures disinfection performance over a range of UV transmittance (UVT) values, flowrates, and a variety of target organisms.

  • 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.

  • 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..

  • 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.

WASTEWATER DISINFECTION VIDEOS

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.
