    Emerging Contaminants: PFOS AND PFOA

    PFCS are manmade fully fluorinated compounds which are not naturally found in the environment, are used in a variety of products such as fire fighting foams, coating additives as a surface-activeagent. PFOS (perfluorooctane sulfonate) and PFOA (Perfluorooctanoic acid) are the most commonly produced PFCs, and large amounts of PFCs have been produced during past manufacturing processes and released to the air, soil and water.

  • Granular Activated Carbon Removes PFOA From Drinking Water
    Granular Activated Carbon Removes PFOA From Drinking Water

    In the fall of 2015, a small village on the border of Vermont in New York State, tested positive for Perfluorinated Compounds (PFCs), specifically Perfluorooctanoic Acid (PFOA), in the municipal drinking water. The influent levels of PFOA in the water were above 600 ng/L, and thus considered harmful to village residents. Realizing that PFOA was on the U.S. EPA Contaminant Candidate List, the Village solicited the services of engineering firm CT Male Associates to investigate treatment options and provide a treatment system.

    Chlorine vs. Chloramine: A Tale Of Two Chemistries

    In drinking water treatment’s ongoing battle between disinfection and disinfection byproducts (DBPs), most water utility customers are oblivious to the process. One thing they do notice, however, is when their water smells or tastes bad. Here are some insights that can help water treatment plant (WTP) operators deal with their internal concerns about DBPs and residual chlorine or ammonia levels, as well as their external concerns about customer perceptions of water quality.

  • Multi-Barrier Disinfection Strategy - New York City (Case Study)
    Multi-Barrier Disinfection Strategy - New York City (Case Study)

    New York City is home to more than 8 million people, making it the most populous city in the United States. The majority of New York's drinking water is supplied by the Catskill/Delaware watershed, located approximately 100 miles outside the city. Historically, NYC has not filtered the water from this system, nor did they require any additional barriers to microbial contaminants due to the pristine nature of the watershed.

  • City Water Treatment Processing Application Activated carbon (AC) filtration is most effective in removing organic contaminants from water. Organic substances are composed of two basic elements, carbon and hydrogen. Because organic chemicals are often responsible for taste, odor, and color problems, AC filtration can generally be used to improve aesthetically objectionable water as well as remove chlorine.
