Abstract: A wastewater treatment system is provided having a pretreatment tank which receives wastewater from a wastewater source, and an aeration tank which is in fluid communication with the pretreatment tank. A recirculation pump is carried in the aeration tank and returns wastewater from the aeration tank to the pretreatment tank. The recirculation pump returns the wastewater according to a recirculation ratio R:I where R is the volumetric flow rate of wastewater through the recirculation pump and I is average volumetric flow rate of wastewater entering the pretreatment tank. A control panel cycles the recirculation pump on and off according to the recirculation ratio.

Abstract: A platform for a cemetery lowering device comprising a one-piece base having a tapered edge and a non-skid surface, wherein the one-piece base comprises an opening for a casket to be lowered through the base, a frame and skin, and one or more receptacles for adjustable-height footings. The frame and skin may be formed of a single piece of polymer, fiberglass, or metal. The non-skid surface may comprise grooves. The base may comprise a guide for positioning the cemetery lowering device on the base. The guide is an impression in a surface of the base. The base may comprise a first flange around a perimeter of the opening extending vertically from a top surface of the base. Each one of the receptacles is threaded such that height adjustments of the one of the adjustable-height footings can be performed by rotating the one of the adjustable-height footings.
