DRINKING WATER DISINFECTION RESOURCES

• 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.

• Calcium Hypochlorite Feeder Selected As Primary Solution For Municipal Water Treatment Plants

  Long Beach Township is the largest town on Long Beach Island, New Jersey. With 18 miles of beaches, the town is a major tourist destination. Population exploded during the summer months from approximately 3,000 to over 100,000. This can be a challenge for the town's drinking water facilities, with demand increasing exponentially during the tourist season.

• Byers Gains Stable Chlorination And Reduced Maintenance With Constant Chlor® MC5 System

  Byers is an unincorporated rural community in Arapahoe County, Colorado, approximately 50 miles east of Denver. Byers Water & Sanitation District provides drinking water to this area. The district operates five wells – each approximately 700 feet deep. Two wells are typically used in the winter and four in the summer. Annual water use averages 140,000 gallons per day for the district’s 500 active service connections.

• Breaking The Causative Chain Of Legionellosis

  Legionnaires’ disease first garnered public attention in 1976. After attending an American Legion convention at a Philadelphia hotel, 221 people became ill, with 34 dying of a mysterious illness. The U.S. Centers for Disease Control and Prevention (CDC) launched a major investigation, and in 1977 identified the responsible bacterium, naming it Legionella.

• The Highly Consolidated U.S. UV Water Treatment Equipment Market

  The U.S. ultraviolet water (UV) water treatment equipment market for industrial and drinking water applications is competitive, mature, and saturated. The market is dominated by a few leading players holding significant market shares.

• Understand The Risk Of Stagnant Water To Reopen With Safety And Reliabilty

  The year 2020 has marked a time when the risk of disease has altered plans for how we work, shop, learn and travel. As the work force re-enters offices and more industrial and commercial facilities reopen, there looms another risk waiting in our water systems – Legionella.
