The present technology relates to control systems for use with fluid treatment systems. In one embodiment, for example, a fluid treatment system includes a vessel configured to receive a fluid having one or more constituents and to separate one or more constituents from the fluid. The system can also include a tube extending along at least a portion of the vessel and a sensor. The tube can be in fluid communication with a pressurized air source, and the sensor can be configured to obtain a measurement of an operating parameter. The system can also include a controller in communication with the sensor and pressurized air source. The controller can execute one or more algorithms to determine a filter parameter based on the measurement of the operating parameter, compare the filter parameter to a threshold, and, based on the comparison, activate or deactivate the pressurized air source.

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 multi-port, multi-mode valve includes: a valve housing; multiple ports on the valve housing, a spacing between first and second ports being smaller than a spacing between third and fourth ports; and a stemshell positioned at least partly inside the valve housing, the stemshell having at least two channels configured for selectively coupling one or more of the ports to a selected at least other one of the ports.
