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.

  • Capital Controls® Series 1041A Automatic Switchover

    The Automatic Switchover system Series 1041 provides safe, reliable switching between two gas (pressure or vacuum) or two liquid (pressure or level) sources assuring an uninterrupted supply of chemical to the application. Automation of all functions (switchover, system initialization, configuration, lamp test, and safety functions) is done with an internal programmable logic controller for operational flexibility, enhanced reliability, and ease of use. If needed, local manual override is conveniently available for operator control to maintain continuous operation.

  • UV Technology Offers Solution For Emerging Water Crisis

    Many are turning to UV as an effective barrier to enable the reuse of wastewater, for indirect reuse, and aquifer recharge.

  • Constant Chlor® Rapid Rate Feeder Fast-Acting CSO Disinfection System

    The Constant Chlor® Rapid Rate Feeder is a highly-customizable large scale CSO disinfection system for wastewater applications. CSOs may occur after a large rainfall or melt, causing wastewater to exceed the capacity of the system. When used with Constant Chlor® Plus Briquettes, the Rapid Rate feeder is able to quickly disinfect the large volume of wastewater during a CSO event.

  • 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.
