WASTEWATER DISINFECTION RESOURCES

WASTEWATER DISINFECTION SOLUTIONS

  • ClorTec® Inspection And Maintenance Program

    De Nora Water Technologies has developed a comprehensive preventative inspection and maintenance contract program for our ClorTec® on-site sodium hypochlorite generation system.

  • TurboCoag System For Chemical-Free Water Purification

    Avivid's patented electrocoagulation system is a chemical-free and cost-effective water treatment solution. This wastewater treatment technology meets the demands of customers that need to reduce pollution abatement costs, comply with EPA regulations, and reduce water consumption/waste in response to the growing demand in the water market and diminishing clean water resources.

  • EST Dry Emergency Gas Scrubber Systems

    De Nora Water Technologies’ EST dry emergency scrubbers are engineered to meet national codes for the mitigation of hazardous gas releases from pressurized 150-pound cylinders and one-ton containers of chlorine, sulfur dioxide, ammonia and other toxic gases.

  • GWT Zeroturb Bio-Organic Liquid Flocculant

    GWT advanced ZeoTurb™ is a unique advanced bio-organic liquid flocculant.

  • ETS-UV™ For Wastewater Treatment

    Many municipalities had adopted ultraviolet (UV) disinfection treatment over chemical based disinfection.  UV disinfection is efficient, low cost and an environmentally friendly way to disinfect water.  The process is safer for operators and the community; UV is a chemical free process that adds nothing to the water but light.  Read more about how the UV disinfection works.  Unlike chlorine, UV disinfection is able to inactivate pathogens such as Giardia and Cryptosporidium.  Discharged wastewater with these pathogens becomes dangerous drinking and recreational water for downstream communities.

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.
