Employing non-fouling Dif-Jet™ gas injectors to mix large quantities of dissolved oxygen into wastewater, Aeration System eliminates odor and reduces BOD in animal waste and sanitary waste lagoons. System uses 400–1200 gpm shore based dry pit type, glycol cooled, electric submersible pumps designed to handle solids up to 3 in. diameter. Oxygenated wastewater is returned to wastewater lagoon at 550 gpm via discharge pipe, establishing vigorous circulation in lagoon.
