Full Description

This report summarizes the findings of the membrane bioreactor (MBR) pilot tests. The hollowfiber MBR unit, "Zeeweed" manufactured by Zenon Environmental, Inc., was configured toreceive West Point WWTP primary influent and West Point WWTP primary effluent. Thesestudies were divided into several phases in order to test several different combinations ofparameters as follows: Phase 1a/1c - Nitrification/Denitrification at 10 day Aerobic Sludge Age, 6 gpm;Phase 1b - Nitrification/Denitrification at 10 day Aerobic Sludge Age, 8 gpm;Phase 2a/2b - Nitrification/Denitrification at 6 day Aerobic Sludge Age, 6 gpm;Phase 3a - Biological P Removal at 6 day Aerobic day Sludge Age, 6 gpm flow; and,Phase 3b - Biological P Removal at 6 day Aerobic day Sludge Age, 9 gpm flow.The focus of these pilot tests was to evaluate the MBR process as a secondary treatment systemto produce Class A reuse water. The specific goals for the pilot study were:to achieve effluent ammonia concentrations to achieve effluent nitrate concentrations to achieve effluent nitrate concentrations to achieve effluent turbidity to achieve effluent TP and,to meet Class A reclaimed water standards. Includes tables, figure.
