Abstract

The present invention is drawn to a unique method for treating anaerobic bodies of water including, but not limited to, agricultural waste treatment lagoons. The treatment method of the present invention includes the steps of analyzing the characteristics of the wastewater and sludge to be treated in an animal wastewater lagoon, identifying and propagating beneficial aerobic bacteria such that a selective dominance of the beneficial aerobic bacteria may be established in the animal wastewater lagoon, sizing an aeration means according to the quantity of water to be treated, aerating the animal wastewater lagoon and aerobically treating the wastewater in the animal wastewater lagoon further comprises propagated aerobic bacteria selected to aerobically digest organic material, and clarifying the wastewater by injected the aerobically treated wastewater with a polymer.
