    FILTRASORB 400 Provides PFAS Solution For Air Force Base In Interior Alaska

    When Eielson Air Force Base, located in the interior of Alaska, found high levels of perfluorooctanoic acid (PFOA) and perfluorooctane sulfonate (PFOS) in their drinking water, they needed a solution that was effective, cost-efficient, and operable in extreme temperatures. Calgon Carbon’s Model 10 adsorption system, filled with FILTRASORB 400 granular activated carbon (GAC), was determined to be the best option.

  • Water Treatment Filter Monitoring
    Water Treatment Filter Monitoring

    A municipal water utility follows a straightforward method for providing clean water to its residents: It pulls water out of a nearby river, filters out the impurities, and then funnels the water into a reservoir to be ready when residents turn on their taps. The water provider needed to improve sand filter consistency and boost performance of its overall fleet of filters in its water treatment plant. To do this, it needed to identify and monitor for poor filter performance while prioritizing filter maintenance.

    Calgon Carbon Initiates Emergency Response To PFAS Detection

    Blades, Delaware, a small town in Sussex County, provides drinking water to more than 1,300 residential and business locations throughout the community. In 1981, the citizens of Blades voted to improve their water and sewage facilities by establishing a central water supply and tying all properties into the nearby Seaford Sewer System. By February of 1982, the project was complete and since then the town has had a clean and safe municipal water supply.

    WRF Hosts Capitol Hill, State-Of-The-Science Briefing On Harmful Algal Blooms

    To make informed decisions about how to limit exposure to cyanotoxins, utilities need information to select and implement a comprehensive and technically sound management approach. The Water Research Foundation (WRF) has been actively involved in developing effective innovative solutions to help utilities address this challenge and protect public health.

  • Analyzing Water Quality Parameters When Choosing AOP Systems For Water Treatment
    Analyzing Water Quality Parameters When Choosing AOP Systems For Water Treatment

    In water and wastewater treatment, chemistry is king. Treatment options are evaluated depending on the quality of water to be treated and the treatment application. Treatment systems including AOP systems, are designed to specifically target certain contaminants and remove or reduce them from the water. This takes places through the power of chemical reactions. Even biological treatments involve chemistry at their core.

  • Benefits And Disadvantages Of The Advanced Oxidation Process
    Benefits And Disadvantages 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.

    Disinfection Tech Trials: How Calcium Hypochlorite Feeders Won Over Long Beach Township WTPs

    In 2012 Long Beach Island, New Jersey, was pummeled by the catastrophic storm surge of Hurricane Sandy. Three of the town's four water plants were badly damaged. Plans were made to rebuild the facilities to higher standards to withstand potential storm impacts. 

  • EPA Outlines Possible Solutions To Looming Perchlorate Limits
    EPA Outlines Possible Solutions To Looming Perchlorate Limits

    The U.S. EPA is gearing up to limit perchlorate in public drinking water systems, so municipalities should start preparing to adopt the appropriate testing and treatment technologies. In a recent report, the agency identified several technologies as the best available to address the perchlorate problem.

  • Secret To Disinfection Monitoring For High Chlorine Residual Wastewater Applications

    Some wastewater applications require chlorine residuals greater than can be effectively monitored using DPD due to the oxidation of the Wurster dye to a colorless Imine. Such applications include industrial wastewater processes that inherently have a high chlorine demand thereby requiring a more robust monitoring method.

  • Selcoperm Electrolytic Chlorination Systems The particular advantage of on-site generation of chlorine with a Selcoperm system from Grundfos is the fact that no significant unpleasant by-products are generated.
  • Emerging Pollutants: The Role Of Activated Carbons

    The presence of active pharmaceutical ingredients, radio-opaque substances and endocrine disrupting chemicals in raw water sources is a relatively new emerging issue in relation to drinking water quality. However, the influence of pollutants on health and general well-being is becoming apparent with the incidence of carcinoma increasing and fertility rates being affected. A solution for the efficient removal of these substances from water use by production sites is required.
