Dissolved methane management and post-treatment for non-potable water reuse of staged anaerobic fluidized-bed membrane bioreactor effluent
Abstract/Contents
- Abstract
- Mainstream anaerobic wastewater treatment with the staged anaerobic fluidized-bed membrane bioreactor (SAF-MBR) shows promise to transform secondary wastewater treatment into an energy-positive, decentralizable process. However, prior to deployment in the field, more information is required to address the issues of dissolved methane recovery, compliance with prevailing regulations, and compatibility with polishing unit processes. California water reuse regulations presuppose aerobic treatment, presenting compliance challenges for the SAF-MBR without additional post-treatment compared to conventional activated sludge. Field experiments were conducted with a demonstration-scale SAF-MBR process to evaluate dissolved methane recovery and effluent polishing to reduce trace organic contaminants. Post-treatment consisted of an air stripping column for dissolved methane recovery, aerobic polishing, regenerated activated carbon filtration, and UV disinfection. Post-treated water was applied to planter beds, and the fate and transport of trace organic contaminants as well as water quality surrogates was analyzed through the post-treatment train. Results will inform future designs for non-potable water reuse utilizing the SAF-MBR, advancing this energy saving technology closer to full scale use in the wastewater sector.
