Abstract: A controller valve with a valve body and a valve cartridge. The valve body has a water inlet, a primary water outlet, and a bypass water outlet. The valve cartridge is positioned within the valve body and has a diaphragm that fluidly isolates an upper chamber from a lower chamber within the valve cartridge. A piston is attached to the diaphragm and is configured to move within the valve cartridge between an upper position and a lower position. When the piston is in the upper position, the valve cartridge limits water flow through the primary water outlet and allows water flow through the bypass water outlet, and when the piston is in the lower position, the valve cartridge allows water flow through the primary water outlet and limits water flow through the bypass water outlet.

Abstract: A pool control system with a controller valve, a distribution valve, and a microcontroller. The controller valve has a primary water outlet and a bypass water outlet. The controller valve is configured to move between an open configuration in which the water passes from a water inlet to the primary water outlet and a closed configuration in which the water passes from the water inlet to the bypass water outlet. The distribution valve has an inlet port fluidly coupled to the primary water outlet and a plurality of outlet ports with an outlet port aperture. The outlet port aperture is configured to align with a new outlet port each time the controller valve moves from the open configuration to the closed configuration. The microcontroller is configured to discharge water from the pool control system by controlling the controller valve to change the configuration between the open and closed configurations.

Abstract: A backwash filtration system comprising a backwash discharge port, a sedimentation collection and separation system, and a final filtration chamber. The backwash discharge port is coupled with a pool filter system and is configured to pass backwashed water from the pool filter system to the sedimentation collection and separation system. The sedimentation collection and separation system has a plurality of sedimentation chambers that are vertically stacked and a plurality of baffles configured to reduce the migration of sediment within the sedimentation chambers. A path for water flow passes down sequentially through each of the sedimentation chambers. The final filtration chamber receives the backwashed water from the sedimentation collection and separation system, filters the backwashed water through a final filtration medium, and passes the filtered water to a water return line of the pool filter system or to a pool of water.

Abstract: A method for simultaneous filtration and non-discharge backwash operation of a pool filter. Water is received from a pool of water and passed to a control valve having a backwash nozzle aligned with a first filtration chamber. The water is forced down through all of the filtration chambers except the first filtration chamber and forced up through the first filtration chamber. The backwash nozzle is aligned with a second filtration chamber. The water is forced down through all of the filtration chambers except the second filtration chamber and forced up through the second filtration chamber. The water is passed through the backwash nozzle and an internal backwash valve to a sedimentation collection and separation system, where sediment is settled out of the water and the water is filtered through a final filtration media within the final filtration chamber. The water is returned to the pool of water.

Abstract: A pool filter system comprising a plurality of filtration chambers configured to filter pool water, a water supply inlet, a water return line, and a control valve. The water supply inlet is configured to receive unfiltered water from a pool of water. The water return line is configured to return filtered water to the pool of water. The control valve receives water from the water supply inlet. The control valve has a backwash nozzle configured to rotate and sequentially align with each of the plurality of filtration chambers. The backwash nozzle has a first position aligned with a first filtration chamber and a second position aligned with a second filtration chamber. The control valve is configured to backwash water through the first filtration chamber when the backwash nozzle is in the first position and through the second filtration chamber when the backwash nozzle is in the second position.
