ABSTRACT:
A method and apparatus to convert a top tube sheet precoat filter apparatus to a bottom tube sheet precoat filter apparatus. A cannister member is supported within the existing filter tank in place of the existing tube sheet dividing the filter tank into an upper influent compartment and a lower effluent compartment. A plurality of precoat filter elements extend upwardly from the lower end of the cannister member into the influent compartment. An influent conduit directs liquid to be treated into the influent compartment and an effluent conduit withdraws treated liquid from the effluent compartment. The existing influent conduit is utilized as the effluent conduit and the existing drain is modified for utilization as the influent conduit. A gas surge conduit and vent are provided to permit utilization of the gas scour backwash technique.
