WASTEWATER DISINFECTION SOLUTIONS

  • Water Champ® FX Induction Systems Provide Superior Mixing

    The Water Champ® FX Chemical Induction System from Evoqua has set the benchmark in chemical feed and disinfection with its innovative design and versatile applications for chlorination, dechlorination, chloramines, pH adjustment and rapid mix. The system provides superior mixing intensity maximizing chemical reaction while using less energy. Independent third party testing has proven that a Water Champ system can provide up to 40% better power to flow-rate ratios compared to other induction mixers or conventional methods.

  • 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.

  • OaSys iCT™: Next-Level Dosage Control For Chemical Disinfection

    When chemical disinfection is used, inherent variability in plant processes (e.g. flow events, plant upsets) can result in inadequate public health protection and risk of permit violation. To avoid these disruptions, WRRFs regularly overdose disinfectant, resulting in excessive cost for disinfectant and quenching chemicals and increasing sensitivity to chemical market conditions (supply disruptions, price increases).

  • ClorTec® DN On-Site Sodium Hypochlorite Generators

    The latest generation of brine electrochlorination technology, the ClorTec DN range, offers simple operation and maintenance as well as unrivalled safety advantages.

  • 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.

WASTEWATER DISINFECTION VIDEOS

This Pinnacle Academy session delivers a clear, practical, and technically informed exploration of ozone in water and wastewater treatment. The presentation walks viewers through ozone’s molecular properties, production methods, and behavior in water, highlighting why it is a powerful, fast-acting, and residue-free oxidant.

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.
