Membrane-Aerated Biofilm Reactor (MABR): CR2C is testing and evaluating an MABR system developed by Fluence Corporation ( for decentralized wastewater treatment and reuse. The system is integrated into a 20 foot shipping container operating at one of the Codiga Center test bed bays from January 2018 through February 2019. MABRs deliver low-pressure air into gas-permeable membrane sleeves inserted into the wastewater. Air can diffuse through the membrane into the water, potentially requiring less energy to aerate water than conventional aerobic treatment processes. A biofilm growing on the membranes also has the potential to achieve simultaneous nitrification and denitrification. CR2C is evaluating the performance of this system relative to California Title 22 non-potable water reuse standards. The final report detailing results from this study is available here: Final Report

Pure Water Extraction from Wastewater: CR2C is testing a Forward Osmosis/Reverse Osmosis (FO/RO) system first developed by NASA for treatment and reuse of greywater (water from showers, handwashing sinks, and laundry). The system uses a highly saline solution to draw water from wastewater through a forward osmosis membrane, then uses reverse osmosis to produce clean water and regenerate the saline solution for the FO process. The trailer-mounted system will be deployed in one of CR2C's test bed bays from August 2018 through February 2019, and be evaluated for treatment of greywater and wastewater.
