A unitary method and system for the continuous clarification, and if desired, purification of a liquid medium containing solid particulate matter is described which system comprises. (a) means for delivering a continuous stream of the liquid medium containing the solid particulate matter to a first separator means wherein solid matter having a nominal diammeter greater than about 3 millimeters is removed from the stream; (b) a pump capable of pressurizing the stream discharged from the first separator and conduits connecting the pump to the first separator means and to a second separator means; (c) second separator means capable of removing from the pressurized liquid stream solid maaterial having a nominal diameter less than about 3 millimeters and greater than about 75 microns; (d) a flocculating unit, and associated conduits for receiving the liquid stream discharged from the second separator, said flocculating unit comprising means for chemically treating the liquid stream as it passes through to flocculate solid particulate matter suspended in the liquid stream; (e) a fine filer means and associated conduits for receiving the presurized liquid stream discharged from the flocculating unit, said fine filter means comprising a filter medium which entrains and separates from a continuous pressurized liquid stream passing therethrough solid particles having a nominal diameter in excess of about one micron; (f) discharge means associated with the fine filter unit for delivery of a stream of clarified liquid medium; and optionally, (g) a chlorination unit and associated clarified liquid medium wherein chlorine is dissolved in the liquid to destroy bacterial and virial contaminants and discharge means for delivering a stream of purified liquid medium. |
