Abstract:
1. A vacuum assisted solid-liquid separation apparatus for treating contaminated liquids contaminated with undesired solids and gasses, comprising: (a) an enclosed separation tower having an upper end and a lower end opposite thereto, a longitudinal axis oriented substantially vertically through the upper end and the lower end, an outer wall, a top wall connected to the outer wall at the upper end and a bottom wall connected to the outer wall opposite the top wall, the outer wall having an inside surface and an outside surface; (b) a tower interior space defined as the space within the outer wall, top wall and bottom wall; (c) a contaminated liquids inlet located proximate the vessel lower end for introducing the contaminated liquids into the tower interior space; (d) a clarified liquids outlet located above the contaminated liquids inlet for discharging the clarified liquids to a desired location; (e) a plurality of baffle plates disposed in the tower interior space in a spaced apart relationship, with at least some of the baffle plates being angularly disposed with respect to the longitudinal axis of the separation tower to define a generally serpentine fluid flow passageway, (f) one or more solids discharge ports located in one or more of the downward slope corners; (g) a standoff conduit in fluid communication with the one or more solids discharge ports for receiving solids from the contaminated water through the one or more solids discharge ports, the standoff conduit having at its lower end a solids outlet port; (h) a vacuum inlet in fluid communication with the tower interior space and located above the clarified liquid outlet for pulling a vacuum on the tower interior space to urge contaminated liquid into the contaminated liquid inlet and up through the serpentine fluid flow passageway to the clarified liquid outlet; (i) one or more sources of vibrational energy applied to the separation apparatus; and (j) one or more electrocoagulation electrodes housed within said serpentine fluid passageway capable of discharging an electrical current into the fluid, wherein said electrodes are capable of alternating between a positive polarity and a negative polarity and are controlled by process control equipment.
