Abstract:
A filter system for filtering liquids having particles in suspension comprising: a) a first tank for receiving said liquids having particles in suspension, said first tank having a vertically movable wall therein which divides said first tank into two compartments, a first compartment for receiving said liquid having particles in suspension and a second compartment into which said particles in suspension settle and form a sludge; b) a second tank arranged to receive the sludge from said second compartment and having a grid-tank with a renewable filter bag therein, said sludge from said first tank being received in said filter bag, said filter bag retaining said particles from said sludge and liquid from said sludge flowing out of said filter bag and through said grid-tank into the remainder of said second tank; and c) a third tank for receiving said liquid from said second tank thereby producing a filtered liquid for recycling.
