Abstract: 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.

Abstract: The present invention relates to a rotary pressure filter comprising a filter drum, a housing, and at least one separating element which divides a process chamber in a gas-tight manner into a plurality of process portions. A sensor is arranged on the side of at least one separating element that faces the housing. The sensor comprises a coil and a rod which is arranged inside the coil. The rod is designed to be displaced in the coil on the basis of a change in the distance of the separating element from the sensor. The invention further relates to a method for detecting wear of a separating element of a rotary pressure filter.

Abstract: The present invention relates to a filtering panel (100) for a disk filter and a disk filter for water purification, comprising a metal filter cloth (16, 116) such as a stainless steel filter cloth, pre-tensioned in both warp and weft directions and fastened to a frame (10, 110) comprising a peripheral portion (11, 111), which is integral with an inner grillwork (12) and which divides the inner area of the peripheral portion (11, 111) into fields (15, 115). The frame (10, 110) comprises a plastic material reinforced with glass fibers or carbon fibres such as polypropylene loaded with fibreglass in an amount of at least 20 weight percent. Each field of the grillwork (12, 112) has an area not exceeding 10% of the inner area of the peripheral portion (11, 111). The pre-tensioning of the filter cloth (16, 116) in both directions is from at least 20% of the yield stress of the cloth (16, 116). Further the present invention relates to a disk filter comprising said filtering panels (100) and method of making said filtering panel (100).
