Method and System for Optimizing Lightweight Biodigester

A method for optimizing lightweight biodigester comprising the following steps:

• connecting a small sewage receiving tank to at least one small anaerobic digesting tank in a way that liquids overflow from the sewage receiving tank into the at least one small anaerobic digesting tank;
• connecting the at least one small anaerobic digesting tank to at least one gray water receiving tank in a way that liquids overflow from the at least one small anaerobic digesting tank into the at least one gray water receiving tank;
• dumping sewage into the small sewage receiving tank;
• separating solids and liquids, with solids settling at the bottom from the force of gravity;
• digesting the solids using hydrolysis;
• draining the overflow of the small sewage receiving tank into the at least one small anaerobic digesting tank;
• digesting the contents of the at least one small anaerobic digesting tank using at least one of acidogenesis, acetogenic, and methanogenesis digestion;
• and
• draining the excess liquid from the at least one small anaerobic digestion tank to the at least one gray water receiving tank for gray water disposal;
• wherein the overflow of the small sewage receiving tank is excess liquids, accompanying suspended solids, and other byproducts resulting from the hydrolysis process.
