Regenerative Media Filter Cleaning Apparatus and Method

A water filtration system, comprising:

• a regenerative media filter vessel having an inlet fluidly connectable to a feed source comprising water to be filtered, a first outlet fluidly connectable to an end use configured to receive filtered water, and a second outlet fluidly connectable to a drain, the regenerative media filter vessel housing a tube sheet comprising a plurality of tube elements configured to have particulate media on a surface thereof during operation thereof;
• a pressure sensor subsystem comprising an inlet pressure sensor and an outlet pressure sensor, configured to measure a differential pressure across the regenerative media filter vessel;
• a filtrate line having an inlet fluidly connected to the first outlet of the regenerative media filter vessel and an outlet fluidly connectable to the end use;
• a feed line having an inlet fluidly connectable to the feed source and an outlet fluidly connected to the inlet of the regenerative media filter vessel;
• a recirculation line having an inlet and an outlet fluidly connected to the regenerative media filter vessel;
• an end use valve positioned on the filtrate line and configured to allow passage of the filtered water to the end use;
• a feed valve positioned on the feed line and configured to allow passage of the water to the regenerative media filter vessel;
• at least one recirculation valve positioned on the recirculation line and configured to allow passage of at least one of the water and the filtered water through the recirculation line;
• at least one pump configured to direct the water through the water filtration system;
• and
• a controller operably connected to the pressure sensor subsystem, the end use valve, the feed valve, and the at least one recirculation valve, the controller configured energize the at least one pump and respectively actuate the end use valve, the feed valve, and the at least one recirculation valve to:
• direct the water through the regenerative media filter vessel in a first direction for operation in a filtration mode for a first period of time until the pressure sensor subsystem measures the differential pressure in a first predetermined differential pressure range, and direct the filtered water through the regenerative media filter vessel in a second direction, opposite the first direction, for reverse recirculation in a cleaning mode responsive to the pressure sensor measuring the differential pressure in the first predetermined differential pressure range for a second period of time.

A method of facilitating filtration of aquatic or recreational facilities water, comprising:

• a pressure sensor subsystem comprising an inlet pressure sensor and an outlet pressure sensor, configured to measure a differential pressure across the regenerative media filter vessel,
• a filtrate line having an inlet fluidly connected to the first outlet of the regenerative media filter vessel and an outlet,
• a feed line having an outlet fluidly connected to the inlet of the regenerative media filter vessel and an inlet,
• a recirculation line having an inlet and an outlet fluidly connected to the regenerative media filter vessel,
• an end use valve positioned on the filtrate line,
• a feed valve positioned on the feed line,
• at least one recirculation valve positioned on the recirculation line, and
• at least one pump configured to direct aquatic or recreational facilities water through the regenerative media filter vessel,
• providing a controller operably connected to the pressure sensor subsystem, the end use valve, the feed valve, and the at least one recirculation valve, and programmed to direct the aquatic or recreational facilities water and filtered water through the regenerative media filter vessel responsive to a measurement obtained from the pressure sensor sub system;
• instructing a user to fluidly connect the first inlet of the feed line to a feed source comprising the aquatic or recreational facilities water;
• instructing a user to fluidly connect the first outlet of the filtrate line to an end use configured to receive the filtered water;
• and
• instructing a user to establish a connection between the controller and a user interface.
