WASTEWATER DISINFECTION RESOURCES

WASTEWATER DISINFECTION SOLUTIONS

  • The Active Control Program For Advanced UV Oxidation

    This application note will explore how active control programs lower operational costs of compliant contaminant removal. 

  • 3-Way Valve

    The 3-Way Valve is available in 4”, 6” and 8” sizes and is available as a stand-alone valve or as part of a Vaughan submersible or vertical wet-well Chopper Pump. The valve is a non-plug design using a rotatable CD-4MCu valve disc to allow discharge out of either of the top ports.

  • CHEM-FEED® Plastic Triplex Skid

    CHEM-FEED® Engineered Skid Systems are now shipping! These Skid Systems are simple to operate, easy to order, and includes everything needed for precise chemical feed.

  • Model 4200-EC Gas Vacuum Feeder Controller

    The JCS Industries Model 4200EC Gas Vacuum Chemical Feeder mixes and feeds gaseous chemicals commonly used for water and wastewater disinfection accurately, reliably and safely. The system is comprised of a vacuum injector to safely introduce the gas into the feed-water stream, a reversing servo motor coupled with a V-notch valve to regulate the chemical flow rate, and a control module for complete electronic control and communications.

  • Floor Washer System

    The patent pending Floor Washer System is the Foambuster nozzle/deflector, but with the deflector rotated from below the nozzle to above the nozzle. The inverted splashplate spreads nozzle flow out across a floor in a fairly wide path to wash settled grit, sand or debris into a sump where it can be pumped out by a dewatering chopper pump. The Floor Washer System is particularly useful for attacking deposition problems in Combined Sewer Overflow (CSO) tanks, storm collection tanks, equalization tanks, lift stations, and influent channels.

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.
