DRINKING WATER DISINFECTION RESOURCES

  • 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.

  • 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.

  • 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.

  • 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 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.

  • 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 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.

  • 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.

DISINFECTION SOLUTIONS

  • WEDECO LBX Series Closed Vessel Ultraviolet Reactors by Xylem

    The WEDECO LBX Series is a thousand times proven, energy efficient solution for the disinfection of pressurized wastewater, surface water, process water, and other low UV transmittance liquids.

  • Application Note: Ozone Measurement In Potable Water

    Ozone is a powerful oxidizing agent that can be used to destroy the organic compounds that affect the taste and odor of potable water. Environmental concerns have led to increased use of ozone because, unlike chlorine, it does not form hazardous by-products.

  • Field Pilot Studies

    Pilot tests conducted at numerous facilities demonstrate that Loprest treatment processes successfully reduce iron, manganese, arsenic, nitrate, and many other select contaminants in drinking water to well below the Maximum Contaminant Level (MCL). Loprest can provide self-contained portable, free-standing pilot units or mobile, trailer-mounted units, depending on specific testing needs at each site. Services include unit delivery, setup, and operation. Upon completion of the pilot study, Loprest will prepare a Pilot Study Report and a detailed cost proposal for a full-scale system.

  • Disinfection In Drinking Water: Choosing The Right Chlorine Analyzer For Your Application

    Disinfection is a very important part of the drinking water treatment process, and choosing between an amperometric and colorimetric chlorine analyser is a decision that depends on a variety of factors. Below you will find out why a colorimetric analyser was the right choice for our customer, given their specific situation.

  • UV Package Plant

    Calgon Carbon UV Technologies is pleased to introduce the C3500D/PS Packaged System for UV Wastewater Disinfection. This product uniquely addresses the needs of smaller communities with effluent flows of less than 2.6 million gallons a day.
