ABSTRACT:
A collapsible water treatment digester includes a flexible bladder, a frame, and a plurality of filter plates. The flexible bladder is movable from a collapsed position wherein the bladder is folded into a substantially flattened state to an expanded position wherein the bladder forms a water treatment chamber. The frame is connected to the bladder so as to support the bladder in the expanded position. The filter plates are disposed within the water treatment chamber of the bladder so as to cause a substantial portion of the solids from a wastewater stream introduced into the water treatment chamber to produce a reconditioned water stream dischargeable from the bladder.
