Patent ID: 6849189

Claim:
A protein removal system for removing organic waste from contaminated water comprising: (A) an injector for providing the contaminated water, (B) an eductor for providing gas into the contaminated water, (C) a manifold comprising a plurality of ports for dispersing the contaminated water containing gas, (D) a horizontal reaction chamber for creating small bubbles of the gas in the contaminated water comprising: (1) a plurality of inlets corresponding to the plurality of ports on the manifold, (2) a set of nested, concentric tubes each having essentially the same length including an innermost tube, (3) a physical barrier between each pair of adjacent tubes extending along the length of the tubes, wherein the physical barriers are generally co-linear with each other, and (4) means for securing the position of the tubes relative to each other; wherein each of the concentric tubes contains an opening along its length such that the openings in adjacent tubes are proximal to the physical barrier between the adjacent tubes and are on alternate sides of the barrier such that flow in adjacent tubes occurs in opposite circumferential directions, and the innermost tube comprises an outlet, and (E) a foam collection chamber which receives the contaminated water comprising the small gas bubbles from the outlet of the horizontal reaction chamber, comprising: (1) a foam riser for collecting foam from the top of the foam collection chamber, (2) a tube or pipe for allowing purified water to exit the foam collection chamber.
