Abstract: A method for fluid treatment that provides variable or alternative regeneration cycles within the same fluid treatment device. The duration of all stages of the regeneration cycle can be adjusted depending upon the amount of fluid treated so that regenerant resources such as water are not underutilized and waste is not discharged unnecessarily into the environment. Additionally or alternatively, a regeneration sequence may include a fluid release sequence in which a fluid is released from a water treatment tank by successive linear movement of a piston in a valve assembly.

Abstract: A method and system for fluid treatment that provides fluid release cycles within the regeneration sequence of a fluid treatment device. The fluid release or backwash air cycle permits the slow, controlled and metered release of air or gases from a treatment tank.

Abstract: A system for fluid treatment that provides alternative regeneration cycles within the same fluid treatment device. A second alternative regeneration cycle is available within the same device, which has independent cycles or processes from the first regeneration cycle. The first and second regeneration cycles can be programmed at the same time and be programmed to alternatively run based upon the number of individual cycles run, the time the cycles have run, the amount of fluid that has passed through the device, or the concentration of brine and/or chlorine in the fluid within the device.
