Abstract: A method of filtering water in a system comprising a regenerative media filter is disclosed. The method includes operating the system in a filtration mode, operating the system in a cleaning mode responsive to a differential pressure measurement across the regenerative media filter, and operating the system in a pre-filtration mode after operating the system in the cleaning mode. A water filtration system is also disclosed. The water filtration system includes a regenerative media filter vessel, a pressure sensor subsystem, a filtrate line, a feed line, a recirculation line, a plurality of valves, at least one pump, and a controller. The controller is configured to direct the water through the system. A method of facilitating filtration of aquatic or recreational facilities water is also disclosed. The method includes providing a water filtration system and providing a controller.
