MBBR To MBR – Unique Process Configuration For Pharmaceutical Wastewater Treatment/Reuse
Abstract:Dewberry performed a three month pilot study of a membrane bioreactor (MBR) for the treatment of wastewater generated at a pharmaceutical manufacturing facility. The purpose of the pilot study was to evaluate the performance of the MBR for full-scale installation in support of the planned wastewater treatment plant (WWTP) expansion from 0.5 million gallons per day (MGD) to approximately 1 MGD.
The objectives of the MBR pilot study were to: (1) Evaluate membrane compatibility with the waste stream, (2) Evaluate membrane compatibility with MBBR technology, (3) Evaluate permeate quality, (4) Evaluate flux degradation and cleaning requirements, (5) Confirm membrane sizing requirements for the full-scale system. GE's ZeeWeed® hollow-fiber membrane was selected for pilot testing.
The results of the pilot study indicate that the unit process configuration of MBBR to MBR is technically feasible for full-scale treatment at an industrial pharmaceutical facility.
