AWWA MTC57631

Membrane bioreactor (MBR) treatment of wastewater from a seasonal operated lodge was installed as an upgrade to a conventional septic system. The high quality effluent generated from the MBR allowed the lodge to increase wastewater discharge flows to the existing subsurface adsorption system thus preserving site acreage for guest units and support structures. The MBR is operated from May through October and stored off-line during the winter months. A flexible design allows system capacity to be matched with the variable flows that occur during seasonal operation. Only limited attention by a skilled operations staff with little formal wastewater treatment experience is required to produce a consistent high quality effluent. Includes tables, figures.
