ABSTRACT:
An arrangement and method of retrofitting a filter using a disposable media to use a permanent media belt passed through a filter tank, in which movable carts are positioned at the entrance and discharge ends of the filter tank, and a roll of permanent filter media belt segment is unwound and passed through the filter tank and rewound into a roll on the other cart at the discharge end of the filter tank with the permanent filter media belt segment being cleaned and dried prior to being rewound. Upon complete rewinding of the segment, the movable carts are switched in their positions and the permanent filter media belt segment again unwound to be again passed through the filter tank with the process repeated. A second removable cart can also be positioned at the entrance side of the filter tank with the leading end connected to the trailing end of the previous belt segment automatically to be carried through the filter tank to ensure uninterrupted filter operation by successive feed of the two belt segments.
