ABSTRACT:
A method for treating water is disclosed. The method is applicable for the treatment of waste water within lagoons and ponds wherein the treatment of the waste water is accomplished mainly through aeration. The method comprises steps of: aerating a bounded body of water with a plurality of propeller-type aerators, each aerator having a hollow tube with opposite ends, a longitudinal axis extending between the ends, and a propeller adjacent one of the ends; placing each of the aerators in the bounded body of water with the propeller and tube end adjacent thereto below the top surface of the water and with the longitudinal axis of each aerator disposed at an angle below the horizontal; driving the aerators to create individual circulating flow patterns around each of the aerators; mixing the water by arranging the aerators in a disposition to link the individual flow patterns created by adjacent aerators to one another to form a larger closed overall flow pattern; injecting oxygen from ambient air through the tube into the body of water adjacent the propeller at a rate greater than one pound of oxygen per horsepower/hour; and inducing by means of the propellers of the aerators the closed overall flow pattern at an average linear velocity in a generally horizontal direction through a cross section to flow at the rate of at least 0.25 feet per second.
