    Abstract: A system for rapidly dewatering sludge in large quantities makes use of a filter plate that is capable of supporting heavy mechanized removal equipment without damage to the filter plate. The filter plate is monolithic and includes granular filter material that is rigidified and bonded together. In the disclosed process, sludge is pretreated with a polymer coagulant that breaks up solids and flocculates the sludge particles. The flocculated sludge is then spread on a bed of filter plates. As the bed is being filled, the large coagulated sludge particles settle and water is drawn off by gravity. A vacuum is then applied to the bed and the sludge is rapidly dewatered. Upon completion of dewatering, front end loading equipment may be used to remove the dried sludge cake from the bed.

    Abstract: A method of spreading a pulp for the purpose of drying it naturally, the pulp having a solid fraction which has a d.sub.80 of less than 100 microns. This method comprises the following steps:(a) adjusting the level of solids of the pulp to between 2 and 25%;(b) adding a flocculating agent to the pulp and mixing it with same, the amount of said flocculating agent being between two thirds and 98% of the optimum required for the flocculation of said pulp; and(c) spreading the mixture of pulp and flocculating agent, in the open air, in a bed the sides of which are permeable, and the bottom of which has a slope of less than 5 meters per 1000 meters, said spreading taking place 1 to 20 minutes after the adding and mixing of the flocculating agent.

    Abstract: Modules for use in forming rigid filter beds by laying a plurality of the modules side-by-side upon a flat base are in the form of porous, planar elements having a continuous, polygonal upper surface, a continuous lower surface approximately coterminous to the upper surface, and sides normal to said surfaces of substantially equal depth much shorter than their length, such elements comprising laminated layers, each layer being formed of particulate material of substantially uniform size rigidly fixed together in a matrix of cured binder, the particles of the layers being substantially different in size than the particles of the adjacent layers, the top surface being flat and the bottom surface being channelled. In preferred forms, the modules' surfaces are square, there are only a top layer and a bottom layer, the top layer is much thinner than the bottom layer and the particles in the top layer are appreciably smaller than the bottom layer particles.Methods of forming the modules and of using them to form filter beds are also disclosed.

    Abstract: A waste water filtration and sludge removal system for filtering and removing sludge materials suspended in water resulting from steel pickling and cleaning operations and the like. The system includes a trough-like filtering tank having weep holes along the lower edge draining into an inclined channel for capturing filtered water for reuse, and also includes a multiple layer filter bed containing an upper layer of fine jagged surfaced particles for capturing filtered sludge. The sludge layer deposited on the surface of the upper filter layer is periodically moved by means of an adjustable screed blade toward an elevated discharge station for removal from the tank without significantly disturbing the filter bed. The screed blade may be automatically raised out of contact with the sludge layer when operated in the reverse direction.
