Cities worldwide are facing a mounting water crisis from climate change, population expansion, and deteriorating infrastructure that threatens economic development, social welfare, and environmental sustainability. New strategies are needed for water/wastewater treatment and distribution that will reduce the need to pump water over long distances and provide opportunities to reclaim and reuse wastewater locally. A full-scale pilot hybrid sequencing batch membrane bioreactor (SBR-MBR) wastewater treatment system serving 400 residential units is being tested at the Colorado School of Mines (Golden, Colorado). The pilot system was developed by Aqua-Aerobic Systems, Inc. (Rockford, Illinois) in partnership with Koch Membrane Systems (Wilmington, Massachusetts). The preliminary objective of the pilot study is to assess the economic and technical feasibility of using the SBR-MBR process as a sustainable, decentralized approach for onsite water reclamation and reuse of municipal wastewater effluents. Wastewater characteristics, biological performance and effluent quality of the system will be presented.
