DRINKING WATER DISINFECTION RESOURCES

  • The Department of Defense's USMC Winter Warfare Training Center had a 20-year-old arsenic removal system that needed the previous media replaced. However, the manufacturer of the system had gone out of business. The USMC needed a new CA Water Board-approved system in a very short time frame.

  • Water supply from a mountain lake atop Donner Pass in the Sierra Nevada Mountains was at risk of arsenic contamination. Here’s how Applied Process Equipment solved the problem.

  • There is no question that unpleasant taste and/or odor in drinking water can create negative water quality perception challenges for water utilities. Though taste and odor are not health concerns, consumers still are likely to notice and voice their concerns.

  • The City of Belleville, Ontario was planning on re-developing downtown waterfront property into a public space containing a park and a green space. Unfortunately, the proposed site had a long history as an industrial site – initially for a coal gasification plant from 1854 to 1947 and then as a bulk oil storage facility from 1930 to 1990.

  • Sigura™ calcium hypochlorite offers cooling tower operators and their service providers a highly effective biocide designed for controlling microorganisms to maintain system cleanliness, achieve associated production efficiency gains, and help guard against biofouling. Learn how a West Coast service provider's switch to Calcium Hypochlorite lead to a more consistent chlorine concentration and eliminated the need for frequent pump adjustments.

  • Disinfection has come a long way — enough so to consider alternative options that can help water suppliers avoid harmful byproducts.

  • The ozonation process for water purification is a powerful option for optimal disinfection and the reduction of micropollutants. Still, it may result in the formation of potentially toxic oxidation byproduct bromate in bromide-containing waters. This paper provides a high-level overview of the problem and highlights the main pathways of ozone decomposition and propositions to control bromates formation.

  • Why are living biofilm super-pathogens spreading in water systems, and what is the best way to defeat them?

  • In many water and wastewater treatment applications, there are a number of pollutants that are difficult to reduce by physical, chemical, or biological means alone. In more recent years, there has been a growing concern regarding pharmaceutical drugs in drinking water and aquatic environments. Pesticides get caught in runoff from farms into freshwater supplies. Personal care products are typically washed down the drain into whatever system they are linked to. Landfill leachate is a toxic cocktail of compounds that can leak into groundwater sources. Such contaminants fall into the category of micropollutants, because they are so small. Their size alone is part of the reason, they are so difficult to remove from water and wastewater by certain means. More efficient removal requires a more powerful oxidation process, this process is called an advanced oxidation process (AOP).

  • The New York State Department of Health has recognized the ultraviolet advanced oxidation process (UV AOP) as a treatment solution for 1,4-dioxane. For water providers located in Nassau County on Long Island, it was necessary to pilot UV AOP technology at the various wells requiring treatment in order to confirm treatment efficacy and obtain state approval.

  • Xylem’s Leopold Oxelia™ for Drinking Water Applications

    Biological and chemical contamination in drinking water poses a significant public health risk and plant operators require a treatment system that allows them to produce a safe and reliable supply of clear, good-tasting and biologically-stable finished water with the lowest concentrations of non-desired substances.

  • 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.

  • NeoTech D238™

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

  • Model 420-T Ton Mounted Vacuum Regulator

    The JCS Industries Model 420-T Ton Mounted Vacuum Regulator is designed for years of safe and reliable service.

  • ReFleX™ Efficiency

    For both disinfection and TOC-reduction applications, NeoTech Aqua Solutions’ patented ReFleX™ UV chamber technology represents the state-of-the-art in high-efficiency UV systems by reflecting over 99% of the UV we generate back into the water.
