A lightweight, bioplastic, mobile, floating oil spill mechanical/biological recovery system is dimensionally compact, and quick to assemble. The floating platform can be readily positioned within any waterborne oil/contaminant spill area. After assembly, this platform or apparatus can be directed by either a hand-held digital radio control transmitter or GPS directed mechanism. A lower, multi-roller slip-on belt is designed to be mounted over a circular base support aeration hub assembly with alternating/spaced slotted ring water drainage separators. The belt and aeration assemblies dip bioaugmentation product into the contaminant site thereby exposing microorganisms to both oxygen and target contaminant for treatment and metabolism. Various mechanisms for enhancing metabolic activity of the bioaugmentation product operate in tandem with the primary belt and aeration assemblies to promote effective contaminant metabolism and overall treatment regimes.

An automated descaling system can be integrated into a tankless water heater or can be a separate system that is connected to a tankless water heater. The automatic descaling system comprises a cleaning media chamber and a valve with a motor. The descaling system can be set on an automatic cleaning schedule.

The present invention provides a method of treating wastewater in a wastewater system. The wastewater system comprises a treatment plant comprising a treatment space and a sewer system comprising a sewer space. The treatment plant further comprises a treatment inlet for supplying wastewater to the treatment system from the sewer system. The method comprises the step of: providing a treatment parameter being significant for purification of wastewater in the treatment plant, determining an actual spare plant capacity indicating an amount of wastewater which can be supplied to the treatment space, and determining an actual spare wastewater storage volume indicating an amount of wastewater which can be retained in the sewer space. The amount of wastewater supplied through the treatment inlet to the treatment plant is varied based on the treatment parameter, the actual spare plant capacity, and the actual spare wastewater storage volume.

An exemplary valve control system includes a master controller that wirelessly communicates with a plurality of slave controllers. The slave controllers are each associated with respective devices and sensors. In exemplary arrangements a valve slave controller is associated with a motor that controls a condition of a valve. An exemplary control valve includes a valve body with a plurality of ports (A, B, C, D, E, F) and a plurality of annular flow passages. A piston is selectively movable within a bore within the valve body through operation of the motor and valve slave controller. The valve slave controller is selectively operative to control the position of the piston so as to selectively enable liquid flow through the valve.

A control valve (10) includes a valve body with a plurality of ports (A, B, C, D, E, F) and a plurality of annular flow passages (53, 55,57). A piston (34) which includes a plurality of annular flow passages and a longitudinal flow passage is selectively movable within a bore (32) within the valve body through operation of a valve controller (70). The valve controller is selectively operative to control the position of the piston so as to enable liquid flow through a plurality of flow paths.
