HORIZONTAL AIR SCOURED PRESSURE SAND FILTERS

HORIZONTAL AIR SCOURED PRESSURE SAND FILTERS. The front dome end has connections, which serve for admitting unfiltered water air for air scour, and discharging used wash water from the compartment formed by a vertical weir plate. The outlet connection on the underside of the filter serves for the discharge of filtered
