The breakdown of solids in wastewater is called hydrolysis and may be the rate limiting step of the wastewater sludge treatment process. The microbial fuel cells studied have the capability to produce hydrogen peroxide which can potentially be used to increase the hydrolysis rate. Tests have been conducted on wastewater primary sludge with hydrogen peroxide to determine if it does increase the hydrolysis rate. The tests indicate that it does not dramatically increase the rate, however a microbial fuel cell will be constructed and hydrogen peroxide treated wastewater sludge will be used to determine the positive effects of this method.
