DRINKING WATER DISINFECTION RESOURCES

• Advanced Treatment Systems Tackle Taste And Odor Issues

  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.

• Treating Contaminated Groundwater: Advanced Iron Removal System

  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.

• Stable Chlorination & Easy Chemical Transport For Rooftop Cooling Towers With Sigura™ Cal Hypo

  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.

• Shall We Compromise The Health Effect Of Disinfection Byproducts To Control Waterborne Diseases?

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

• Ozone In Water Purification And Bromate Formation

  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.

• The Menace Of Biofilm And How We Can Tackle It

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

• Pros And Cons Of The Advanced Oxidation Process

  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).

• Successful Piloting Of UV Advanced Oxidation On Long Island For 1,4-dioxane Treatment (Case Study)

  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.

• Inactivation Of SARS-CoV-2 Virus With Preservation Buffer B

  Read the full white paper to learn how testing was performed to confirm that the Preservation B reagent used in LuminUltra® SARS-CoV-2 Environmental Monitoring Kits inactivates the SARS-COV-2 virus to ensure safe handling of samples throughout the assay.

• Monitoring Strategies For Controlling Legionella Growth In Water Systems

  Legionella is a genus of bacteria that are found widely in aquatic environments, particularly in constructed water systems with warm temperatures. These bacteria are known for causing Legionnaire’s Disease and Pontiac Fever. This whitepaper focuses on monitoring strategies that can be used as a component of a water management plan for controlling Legionella growth in various types of water systems (cooling towers, hot water, potable water, etc.) and reducing associated risks.
