PROJECT HIGHLIGHTS

Commissioned March, 2008 Domestic WW, Greenfield Permit(s); Discharge 8/NA/NA    (TN/TP/Turbidity) Municipal -> River MMF Capacity: 0.17 MGD $8.82/gal 1 FTE (Full‐Time Employees) 
Endangered Chesapeake watershed can be cleaned up with the help of MBR technology.

DESCRIPTION

An excess of nutrients discharged into the 64,000 square mile Chesapeake Bay Watershed was the primary driver for selecting MBR technology for the Old Standard WWTP. Listed as an impaired waterway by the EPA, new wastewater treatment plants (point sources) discharging into the watershed must comply with strict new permit requirements. Total nitrogen limits of down to 3 mg/L and total phosphorus limits down to 0.08 mg/l are achievable by using MBR technology. Flat plate membranes were selected because of the ease of operations and maintenance versus competing hollow fiber systems.
