WASTEWATER DISINFECTION SOLUTIONS

  • TrojanUV3000Plus — Wastewater Disinfection System

    The TrojanUV3000Plus® is one of the reasons why UV treatment is now a favored technology in wastewater treatment. Often touted as a flagship UV system, it has demonstrated effective and reliable performance around the world. In fact, over 2,000 municipalities rely on it to disinfect over 30 billion gallons of wastewater every day.

  • GENCLEAN-AQ

    GENCLEAN™ AQ is an NSG 60 certified specialized advanced oxidation treatment specially developed for process water disinfection and wastewater treatment for food & beverage processing companies and fish farms.

  • The Active Control Program For Advanced UV Oxidation

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

  • Sanitaire Taron™ Activated Sludge Filter

    Applying Sanitaire’s wastewater treatment expertise, the innovative Taron Activated Sludge Filter can help plants meet discharge limits and expand capacity in a compact footprint. The Taron filter provides reliable solids reduction from high MLSS concentrations.

  • Chlorine Measurement In Wastewater And Regulated Discharge Requirements

    Homes, industry, schools, and businesses all generate sanitary waste, or sewage. Sewage treatment is a multistage process that cleans up wastewater before discharge or reuse. In the final step of the treatment, disinfectants are added to kill disease-causing organisms. Common disinfectants are chlorine gas and sodium hypochlorite. Chlorine dosage levels are designed to leave almost no residual in the wastewater after treatment

WASTEWATER DISINFECTION VIDEOS

As aquatic invasive species continue to overwhelm hydropower, industrial, and municipal systems worldwide, this webinar explores why traditional filtration and chemicals are falling short—and how a dual-barrier UV approach is emerging as a proven, chemical-free alternative backed by global field results.

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.
