摘要： A process for the preparation of a concentrated filter cake from an admixture of partially-decomposed organic material and a polar liquid using a filter press without the input of thermal heat or superheated steam or other pressurized gas or liquid is provided by this invention. The admixture is mixed with an additional amount of the polar liquid to produce a feed slurry of the admixture having a moisture content of about 90-99% wt. The resulting slurry admixture is then introduced into the filter press having a plurality of filter plates with porous membranes secured along their outlet. The pressure condition introduced inside the filter plate chambers is increased by a pressurized gas or liquid to force the polar liquid from the admixture slurry though apertures contained in the membrane, thereby leaving a filter cake of the partially-decomposed organic material having a moisture content that is lower than the moisture content of the initial partially-decomposed organic material feed. The process and its equipment may be used to treat a variety of partially-decomposed organic material/polar liquid slurry admixtures, including high moisture peat containing water, and reduce the moisture content of the resulting peat filter cake to as low as 60% wt for peat or about 50% wt for a peat/Biochar admixture.

摘要： An apparatus for automatically removing cake deposits from the surface of filter cloths within a filter press is disclosed. The apparatus includes a rod for suspending the cloth in a substantially inverted "V"-shaped configuration. The cloth is then slackened by lowering a rod over which the cloth is folded. The rod is then suddenly forced upwardly under the driving force of a loading means. The rod draws the cloth to a taut, tensioned condition, imparting a whip-like motion to the fabric of the filter cloth. This imparted motion serves to disengage the cake from the filter cloth.
