to achieve very low effluent discharges of various nutrients such as nitrogen and
phosphorus.
The treatment plant consists of two trains with equalization tanks followed by anoxic
and aerobic treatment tanks as well as a membrane biological reactor that the
operator adjusts daily to meet very stringent effluent limits. The operating permit for
the facility requires treatment to advanced wastewater treatment standards of 5mg/1
