Description
Direct application of anaerobic digestion to sewage treatment is normally only possible
under tropical weather conditions. This is the result of its diluted nature and temperatures far from
those suitable for anaerobic conversion of organic matter. Then, direct application of anaerobic
treatment to sewage would require changing temperature, concentration, or both. Modification
of sewage temperature would require much more energy than contained in the organic matter.
Then, the feasible alternative seems to be the application of a pre-concentration step that may be
accomplished by membrane filtration. This research studied the pre-concentration of municipal
sewage as a potential strategy to enable the direct anaerobic conversion of organic matter. Three
different membrane processes were tested: microfiltration, ultrafiltration and forward osmosis. The
methane potential of the concentrates was determined. Results show that biogas production from the
FO-concentrate was higher, most likely because of a higher rejection. However, salt increase due to
rejection and reverse flux of ions from the draw solution may affect anaerobic digestion performance.
