A water discharge management system is provided. The water discharge management system includes a water processing system, a controller provided with an executable recapture protocol, and a plurality of controllable multi-way valves which control and implement a regeneration cycle of the water processing system based upon the recapture protocol. Each controllable multi-way valve is in operable communication with the controller through a signal path. The controllable multi-way valves are responsive to a signal exchanged with the controller through the signal path and operable between a first position connecting an input from the water processing system to a first output, and a second position connecting the input from the water processing system to a second output.

A water delivery control system operates to selectively deliver water from a water source to water use devices. The system includes at least one controller that wirelessly communicates messages with a portable user device. The system includes a water control valve and a motor that is operative to selectively move at least one valve element of the valve. A water meter is operative to measure water flow that corresponds to flow through the valve. The controller is operable to cause the valve to enable or prevent flow through the valve responsive at least in part to water flow data. The controller is operative to determine a water use condition responsive to a water usage pattern, and to cause at least one message to be sent to the portable user device responsive to the determined water use condition.

The invention relates to a process for monitoring the supply of substitution fluid upstream or downstream of a dialyzer or filter arranged in an extracorporeal blood stream. One embodiment provides, for the detection of predilution or postdilution, for measuring the pressure in the blood stream downstream of the dialyzer or filter, predilution or postdilution being recognized on the basis of the change in pressure following the shutting off and/or starting up of the substituate pump provided for conveying the substitution fluid. Another embodiment provides for recognizing predilution or postdilution on the basis of the comparison of the oscillating pressure signal attributable to the substituate pump to a characteristic reference signal. The characteristic reference signal to which the pressure signal of the substituate pump is compared is preferably the oscillating pressure signal of a blood pump arranged in the blood stream for conveying the blood upstream of the dialyzer or filter. In addition, the invention relates to an extracorporeal blood treatment device with a facility for detecting predilution or postdilution, which device operates according to the processes detailed above.

A system and method for the treatment of wastewater. In one aspect, the invention can be a method of treating wastewater comprising: a) introducing wastewater having a first turbidity level into a wastewater treatment system; b) injecting an aqueous polymer mixture into the wastewater to flocculate suspended solids within the wastewater; c) removing the flocculated suspended solids from the wastewater to form a treated water having a second turbidity, the second turbidity being lower than the first turbidity; and wherein the aqueous polymer mixture of step b) is formed by introducing a raw polymer into a re-circulated portion of the treated water.

A filtering apparatus is configured to receive pressurized fluid from a pump. The filtering apparatus has a main inlet, a main outlet, and a filtering branch comprising a first filter. An agitator of a tank from which the pump draws is configured to receive fluid flow from the filtering branch via a proportional valve and an inlet connection. A method of operating a filtering system includes influencing fluid flow from a tank to one or more nozzles via a filtering apparatus; and diverting a portion of the fluid flow through plural filters of a different mesh size back to an agitating mechanism through a lower portion of the tank.
