Application Parameters

When plans were being considered to build a new stadium for the New England Patriots in Foxborough, MA, water supply was a concern. This town of approximately 16,000 people could not support the water demands for a new stadium facility without using a wastewater recycling system. Game days at the stadium would create a strain on the town's water system, and there wasn't an additional wastewater processing site in the area.

The Problem

The East Bridgewater municipal complex located in East Bridgewater, Massachusetts experienced high concentrations of BOD, TSS, and TN in their generated wastewater. The complex needed to upgrade their wastewater treatment system to meet the effluent discharge limitations set forth by The Massachusetts Department of Environment Protection (MADEP).

The Solution

BioprocessH2O provided the municipal complex with an Airlift bioPULSE Membrane Bioreactor (MBR) system. This system is designed for BOD, TSS, and TN removal at the East Bridgewater complex. The Airlift bioPULSE MBR system consists of an activated sludge process and an external membrane filtration system designed to separate the suspended solids so they are able to be removed. The MBR system has high performance and is capable of lowering the BOD, TSS, and TN levels to meet the MADEP permits.

The Results

BioprocessH2O’s Airlift bioPULSE Membrane Bioreactor (MBR) system has a small footprint for plant expansion and is very easy to operate. The MBR’s combination of the activated sludge process and the membrane filtration system will lower the BOD, TSS, and TN limits to meet the requirements set forth by the MADEP.
