Abstract

In field of wastewater treatment, anaerobic treatment is gradually introduced to reduce energy consumption and excess sludge. One more benefit is energy recovery as methane gas which can be used as energy source. The anaerobic treatment is introduced to treatment condensate from kraft pulp process, which contains high concentration of methanol. Methanol is easily biodegradable, but there are difficulties in stability of granule. In this work, pilot scale test with condensate from kraft pulp process was performed, and stability of granule was improved by new chemical addition.
