WASTEWATER DISINFECTION RESOURCES

WASTEWATER DISINFECTION SOLUTIONS

  • Pipeline Flash Reactors for Mixing & Contacting

    Pipeline Flash Reactors (PFRs or spool pieces) utilize high velocity mixing to transfer ozone or oxygen-enriched sidestreams into bulk water flow, all within a compact footprint. With a PFR, ozone or oxygen mass transfer occurs in the pipeline within seconds, eliminating the need for additional tanks or basins.

  • TrojanUV3000B — Wastewater Disinfection System

    The TrojanUV3000®B is a simple, yet robust system designed for small wastewater treatment plants that are looking to treat 1 – 5 MGD (158 – 789 m3/hr). The system is straightforward to use and requires minimal operator involvement thanks to its modular design and proven components. It can be easily retrofitted into existing chlorine contact tanks and effluent channels, and comes pre-tested, pre-assembled and pre-wired to minimize installation costs.

  • Process Monitoring And Control For Increased Productivity And Efficiency

    The Littleton/Englewood wastewater treatment plant, Colorado, put in place processes to effectively monitor the levels of ammonia in their wastewater treatment.

  • GS1440 Sensor H2S

    Water or air, measure H2S where it matters – right at the source.

  • PhotonMaster™ Luminometer

    Reliable data starts with a reliable device. Generate your data from the PhotonMaster, a luminometer that is sensitive enough for the cleanest sample, robust enough for the toughest testing environment, and cost-friendly for any budget.

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.
