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 system and method for monitoring process water treated with a biocide is provided. The system includes a biocide feeding unit and a dissolved oxygen sensor. The dissolved oxygen sensor works in two modes, a biocide feeding mode and a background mode, and alerts an operator when the dissolved oxygen value indicates a fault in the system. A drop in dissolved oxygen during feeding can indicate faulty production of biocide or biocide degradation, both of which can lead to unwanted disinfection by-products.

A second waste stream input is positioned between the reactor inlet end and the reactor outlet end.

Abstract: A system and method for conditioning water is provided. A fluid flow sensor senses a flow of untreated discharge water passing through a water discharge drain line. The sensor generates one of a first sensor signal indicating a flow of the untreated discharge water and a second sensor signal indicating an absence of the flow of the untreated discharge water. A water conditioning controller transmits a first actuation signal to a conditioning agent pump when the first sensor signal is received, wherein a portion of a conditioning agent residing in a conditioning agent reservoir is pumped into the water discharge drain line to mix with the flow of untreated discharge water, and transmits a second actuation signal to the conditioning agent pump when the second sensor signal is received so that the portion of the conditioning agent is not pumped from the conditioning agent reservoir.

Abstract: A control system for a water treatment apparatus that includes a control valve assembly having a servo chamber in which a stationary port defining signal ports is located. A regeneration control disc sealingly engages and rotates on a planar surface of the port disc and selectively communicates fluid signals to water pressure operated components within the control valve.
