    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.

  • 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.

    The Ridgway Water Treatment Plant (WTP) in Elk County Pennsylvania uses a Real Tech Real UV254 online analyzer to achieve a 20-30% savings in annual coagulant use in their conventional water treatment process. Beyond operational cost savings, the Real UV254 system helps the WTP consistently produce high quality drinking water for the town’s 1700 customers.

  • Granular Activated Carbon System Provides Emergency Solution To Combat Algal Toxins
    Granular Activated Carbon System Provides Emergency Solution To Combat Algal Toxins

    Nestled in the Finger Lakes region in upstate New York, the town of Owasco is a popular vacation spot. With about 4,000 residents, the town, along with the nearby community of Auburn, relies on Owasco Lake for its drinking water. In 2016, Owasco and Auburn detected algal toxins in their finished water for the first time. With the busy summer tourist season quickly approaching, GHD contacted Calgon Carbon.

  • On-Site Sodium Hypochlorite Generation Maintains Consistent Chloramine Disinfectant Residual At A Remote Tank
    On-Site Sodium Hypochlorite Generation Maintains Consistent Chloramine Disinfectant Residual At A Remote Tank

    Purissima Hills Water District (PHWD), a county water district, provides chloraminated water service to two-thirds of the town of Los Altos Hills, adjacent to the city of Palo Alto in Northern California. With remote tank locations, low population density (6,800 people) and low water demand (1.61MGD), PHWD is constantly challenged to maintain consistent disinfectant residual levels while simultaneously balancing the safe delivery of chemicals to its tank site at an affordable cost.
