WASTEWATER DISINFECTION RESOURCES

WASTEWATER DISINFECTION SOLUTIONS

  • NeoTech D238™

    The NeoTech D238™ is specially designed to disinfect water and is an essential component in advanced oxidation processes.

  • Dual Diaphragm Chemical Feed For Precise Chem Dosing With No Vapor Lock

    While dosing challenging chemicals can be tricky for operators, there are a range of technologies that will help mitigate problems and ensure smooth, accurate, and dependable chemical dosing.

  • Constant Chlor® Rapid Rate Feeder Fast-Acting CSO Disinfection System

    The Constant Chlor® Rapid Rate Feeder is a highly-customizable large scale CSO disinfection system for wastewater applications. CSOs may occur after a large rainfall or melt, causing wastewater to exceed the capacity of the system. When used with Constant Chlor® Plus Briquettes, the Rapid Rate feeder is able to quickly disinfect the large volume of wastewater during a CSO event.

  • UV Technology Offers Solution For Emerging Water Crisis

    Many are turning to UV as an effective barrier to enable the reuse of wastewater, for indirect reuse, and aquifer recharge.

  • TOC Reduction

    NeoTech Aqua Solutions provides the most efficient and cost-effective UV systems for destroying Total Organic Carbons (TOC’s) in water.  Whether your destroying NDMA, 1,4-dioxane, TCE, MTBE, urea, endocrine disruptors or other organics, only NeoTech Aqua provides ultraviolet TOC reduction with a treatment chamber optimized for low pressure mercury lamps.  As a result, NeoTech Aqua’s UV systems achieve a three times greater TOC reduction per kilowatt compared to standard UV systems, reducing our clients’ costs and energy consumption. In addition to efficiently generating ample 185 nm UV for TOC reduction, NeoTech Aqua’s TOC reduction systems also generate significant levels of 254 nm UV which serve as a powerful disinfectant, providing you both TOC-free and organism-free product water.

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.
