AdEdge Water Technologies was recently engaged by Pharmaceutical Services & Installations (PSI) to provide a treatment option for the Century Packaging Corporation in Las Piedras, Puerto Rico. The packaging facility has a water-supply well which pumps water to a 30,000 gallon storage tank and has a daily utilization of 60,000 gallons per day. Water-quality analyses revealed that arsenic concentrations exceeded the new maximum contaminant level (MCL). AdEdge Technologies Inc. (AdEdge) presented a proposal and was awarded the project for arsenic treatment using adsorption based granular ferric oxide (GFO) technology. AdEdge worked closely with PSI and plant’s engineer Vincenty, Heres & Associates. (VHA) to prepare submittals for approval and subsequent installation of the system. The system was rapidly constructed, shipped, and commissioned in approximately 6 weeks. It was the first arsenic treatment system AdEdge has deployed in Puerto Rico.
