Abstract: A water treatment system is provided that includes a brine tank and a resin tank and a control valve in operative connection with the tanks. The control valve includes a piston that is operative by a first motor to move between different positions to change the flow of water through orifices in the control valve, and a brine valve that is operative by a second motor to open and close the passage between the brine tank and resin tank. The second motor operates the brine valve independently of the operation of the piston by the first motor.

Abstract: A water treatment system is provided including a tank having a top, a control valve, and an air inlet. The control valve is positioned on the top of the tank and in fluid communication with the tank. The control valve includes a plurality of orifices in fluid communication with a source of untreated water, a treated water outlet, a drain, and a source of sterilizing fluid. The air inlet is in fluid communication with the tank and with a first venturi. The control valve is operative to control the flow of untreated water through the first venturi to draw air through the air inlet and into the tank. The control valve includes a sterilizer valve that is operative to open and close at least one passage in fluid communication between the control valve and the source of sterilizing fluid.

Abstract: A water treatment system is provided that includes a control valve. The control valve includes a plurality of orifices and a piston. Movement of the piston is operative to change the flow of water through the orifices. A brine tank is in operative connection with the control valve. The brine tank includes a pump. A resin tank is in operative connection with the control valve and includes an ion exchange resin bed. At least one controller is operatively configured to cause the pump to operate to push brine from the brine tank through the control valve and into the resin tank.

Abstract: A wastewater fluid level sensing and control system is provided. The system comprises a control panel, a reservoir, at least one pump and a fluid level sensing device. The control panel comprises a housing and user interface input and output devices for use with configuring the operation of the control panel. The control panel may be configured to turn on one or more of the pumps to lower the level of fluid in the reservoir. When the level is above a selectable level, the control panel is operative to cause at least one alarm signal to be output.

Abstract: An enclosure for a wastewater fluid level sensing and control system is provided. The enclosure for a control panel of the system may comprise a housing and a non-opaque door. Audible and/or visible alarm devices may be mounted within an interior space formed when the door is closed with respect to the housing. The control panel may be configured to turn on the audible and/or visible alarms responsive to signals from a fluid level sensing device within a reservoir. The control panel may include a touch sensor pad mounted to an inner wall of the housing. Changes in capacitance in the pad as a result of a hand being placed adjacent the sensor on the outside of the housing may be operative to cause the control panel to silence the alarms.

Abstract: An improved pressure activated control apparatus is provided for sensing fluid pressure and triggering one or more switches in response to the fluid pressure, as desired. The apparatus is designed to be placed within a fluid of a reservoir. The apparatus includes a first resilient member, such as a pliable rolling diaphragm or bellofram, having an outer surface exposed to the fluid and responsive to the fluid pressure. The pressure activated control apparatus includes a second resilient member, such as a spring with a chosen spring constant, k, that provides a biasing force against the diaphragm that is opposite the fluid pressure. A transducer is operative to monitor changes in pressure of gases within the apparatus causes by movement of the diaphragm. A controller is responsive to the transducer and selectable fluid level thresholds to activate pumps and/or valves for adjusting the level of the fluid in the reservoir.

Abstract: An improved pressure activated control apparatus is provided for sensing fluid pressure and triggering one or more switches in response to the fluid pressure, as desired. The apparatus includes a first resilient member, such as a pliable rolling diaphragm or bellofram, having an outer surface exposed to the fluid and responsive to the fluid pressure. A force translation and switching mechanism responds to the force exerted by the pressure of the fluid on the outer surface area of the first resilient member to trigger one or more switches mounted on an adjustable switch track assembly within the apparatus housing. The pressure activated control apparatus includes a second resilient member, such as a spring with a chosen spring constant, k, that provides a biasing force against the force translation and switching mechanism. In an embodiment, a plurality of microswitches are each adjustably and removably connected on the switch track assembly.

Abstract: An improved electrical controls enclosure is provided having a modular assembly which is generally tubular in shape, having a generally uniform cross-sectional area throughout its longitudinal axis. The modular assembly comprises (i) a base mounting flange or other fitting as needed, (ii) a pedestal support, (iii) a control panel assembly covered by a control panel assembly shroud, (iv) a reducer coupling for connecting the pedestal support to the control panel assembly shroud, and (v) a cover cap resting atop the control panel assembly shroud. An air and watertight seal is provided between the interior of the pedestal support and the interior of the control panel assembly shroud. The control panel assembly contained within the shroud is seated within a shoulder in the reducer coupling, and is universally rotatable 360 degrees with respect thereto.
