A modular decanting apparatus that is self supporting that may be used in single or multiple configurations to accommodate the removal of wastewater effluent from a wide range of geometric configurations of basins and sizes while substantially reducing the overflow velocities created during a decanting process. It's "Stove Pipe" configuration provides the option of effluent discharge from its top, bottom or mid section and allows effluent to be discharged by internal pump pressure, external pump suction or by gravity flow according to engineering choice. The apparatus includes a weighted support base, and the stove pipe is captured and surrounded by a buoyant doughnut shaped manifold containing fluid inlet valves and a flexible hose with a straight section connecting the manifold to the interior of the stove pipe assembly and also includes a larger flexible hose connecting the stove pipe assembly to the discharge system of a wastewater treatment reactor. Also, the manifold may be made buoyant by an inflatable and deflatable bladder which is controlled by an air hose connecting the bladder to a control circuit of the reactor. The purpose of the inflatable, deflatable bladder is to allow the decanting apparatus to sink beneath the fluid level of the basin during its air/on and settling phases. In a second embodiment two uprising vertical members having their own supports are disclosed which, when spaced apart, capture a buoyant rectangular manifold with multiple fluid inlet valves and a flexible effluent discharge hose.
