ABSTRACT:
A waste treatment system that removes as much of the inorganic and organic solids as possible prior to treating the collected waste material in treatment lagoons. First, inorganic solids, such as sand, are removed, if needed. Then coarse solids are removed, including manure and other organic material such as straw. After removal of inorganic and coarse solids, additional fine solids are removed through two settling basins. For example, after coarse solids separation and fine solids separation, the solids concentration has been reduced by over 80%. Preferably, the coarse solids separation and fine solids separation has reduced size requirements of the treatment lagoons to accommodate an organic loading, as total volatile solids, between 0.00253 lb/ft3of lagoon volume/day×K and 0.0105 lb/ft3of lagoon volume/day×K, where K varies from about 0.4 to about 1.2. Finally, the remaining liquid is treated in the treatment lagoons.
