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.

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.
