WASTEWATER DISINFECTION RESOURCES

WASTEWATER DISINFECTION SOLUTIONS

  • Small Tank Mixing

    Small tank mixing is a lower cost, simplified Rotamix system, using a Chopper Pump and external-mount nozzle assemblies. The external-mount nozzles are sandwiched between 6" ANSI flanges and provide fixed discharge angles off the tank wall.

  • 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.

  • Capital Controls® CHLOR-A-VAC® Series 1420 Chemical Industion Unit

    The Series 1420 CHLOR-A-VAC® affords high efficiency addition and mixing of gases and liquid chemicals resulting in substantial chemical cost savings.

  • 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.

  • Achieving A Delicate Balance To Maintain RO Membranes

    This application note explores the importance of maintaining a delicate balance in reverse osmosis systems to protect RO membranes.

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.
