Collapsible digester
First Claim
1. A water treatment digester, comprising:
- a flexible bladder having a closed lower end, a sidewall extending from the closed lower end, and a treated water outlet extending through the bladder, the lower end and the sidewall of the bladder cooperating to form a water treatment chamber;
a frame connected to the bladder to support the bladder, the frame having a wastewater inlet in fluid communication with the water treatment chamber of the bladder such that a wastewater stream can be introduced into the water treatment chamber; and
at least one filter plate disposed in the water treatment chamber so as to cause solids to be removed from the wastewater stream introduced into the water treatment chamber of the bladder and thereby produce a reconditioned water stream dischargeable from the bladder via the treated water outlet of the bladder.

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.
