WASTEWATER DISINFECTION SOLUTIONS

  • Aqua ElectrOzone Ozone Generation System

    Ozone treatment for water and wastewater has been utilized successfully for several decades and continues to be a viable disinfection solution for both municipal and industrial plants, worldwide.

  • 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.

  • Pipeline Flash Reactor Plus (PFR+)

    Today’s high dosage ozone systems, such as those required by water reuse projects, place extraordinary energy and mixing demands on ozone mass transfer. Mazzei utilized multiphase computational fluid dynamics (CFD) analyses to develop the new PFR+ to address these challenges.

  • NeoTech D222™

    The NeoTech D222™ is specially designed to disinfect water and is an essential component in advanced oxidation processes.

  • WWETCO FlexFilter™

    The WWETCO FlexFilter™ from WesTech uses compressible media to provide an efficient new solution for CSO, Primary Treatment, Tertiary Treatment and Industrial Water Pretreatment. The FlexFilter™ is a simple gravity system with a robust design requiring no moving parts. The combination of tapered media compression, porosity gradient within the media bed and a low flow backwash system make the WWETCO FlexFilter™ one of the most versatile and efficient filters on the market.

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.
