WASTEWATER DISINFECTION RESOURCES

WASTEWATER DISINFECTION SOLUTIONS

  • Trident® HS Package Water Treatment Plant

    The Trident HS package water treatment plant provides multi-barrier protection for difficult-to-treat surface water, groundwater, industrial process water, and tertiary wastewater. The multi-barrier design of the Trident HS, which consists of packaged high-rate settling, adorption clarification, mixed media filtration and optional UV disinfection, is the latest improvement of the original Trident system.

  • Sludge Sucker

    The Sludge Sucker™ unit is a cable-driven sludge removal mechanism that provides cost-effective and efficient removal of lightweight sludges, such as alum or ferric hydroxide, or light iron and manganese precipitates from rectangular settling basins.

  • Constant Chlor® MC5 Feeder

    The Constant Chlor® MC5 Feeder system provides reliable chlorine solutions for water treatment plants, waste water plants and water reclamation facilities. The Constant Chlor® system consistently delivers liquid available chlorine for disinfection applications that kills bacteria, controls algae and removes organic contaminants. The feeders use EPA registered Constant Chlor® Briquettes that work in conjunction with the feeder to produce a fresh concentrated liquid chlorine solution for clean, clear, sanitized water. Treats facilities with up to 10 MGD ranging from a minimum of 5 lbs a day available chlorine to 83 lbs a day available chlorine.

  • 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.

  • VigorOx® WWT II Wastewater Disinfection Technology

    VigorOx® WWT II is a strong wastewater disinfectant for use in wastewater treatment that can replace chlorine or improve the performance of a UV system. VigorOx WWT II, a peracetic acid (PAA)-based formulation, is an equilibrium mixture of acetic acid (vinegar), hydrogen peroxide and water.

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.
