DESCRIPTION
Stratford Green is a housing development in the town of Islip, NY. The existing SBR at the facility had a long history of operational difficulty and had trouble meeting permit. A upgrade was required and since it is a project on Long Island, Suffolk county Department of Health had to approve this project. Several design criteria pertinent to SCDOH were considered while designing this system. Total Nitrogen as high as 70 mg/l was seen in the influent and it needed to be reduced down to 10 mg/l.
