  • Aftersales Solutions And Services

    At De Nora, we are strongly committed to providing aftersales and service support for our entire equipmen portfolio and similar competitive equipment.

  • Disinfection

    As the final step before treated wastewater leaves the plant, effective disinfection is extremely important to protect human health, and the maintenance of the environment. This process eliminates pathogenic organisms that cannot be removed by previous treatment steps and reduces the spread of pathogens in the natural ecosystem.

    USP’s current offerings include our unrivaled in-house CFD modeling expertise that can be used to optimize the injection, mixing and feed rates of PAA to meet the disinfection requirements of a facility. Also, launching later this year, is our OaSys iCT™ is a novel control approach that optimizes disinfection performance by calculating the optimal chemical dosage that accounts for sources of treatment variability in real time. Available for use with PAA or chlorine.

  • 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.    

  • 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.

  • Capital Controls® CHLOR-A-VAC® Series 1420 Chemical Industion Unit

    The Series 1420 CHLOR-A-VAC® affords high efficiency addition and mixing of gases and liquid chemicals resulting in substantial chemical cost savings.

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.
