Abstract: The present invention is an automatic filter cleaning system which includes a solvent dewaxing filter which removes wax from a wax mix slurry and provides a filtrate. Status control apparatus is connected to the filter for affecting the operational status of the filter. Drain apparatus responsive to a control signal controls draining of the filter. Cleaning apparatus is also connected to the filter. A control network connected to the status apparatus, the draining apparatus and the cleaning apparatus controls those apparatus in a manner so as to allow selective changing of the status of the filter from an operational state to a down state to automatically drain the filter and clean the filter while the filter is in the down state.

Abstract: A cycle of filtration is realized for liquids containing solids in suspension and a rotary filter, suited to realize and cycle, where the filtration is carried out by a rotary drum fitted with a filtering surface (2), immersed in a tank containing the liquid to be filtered (26). The phase of the separation of the filtered material deposited on the filtering surface is preceeded by a phase of removal of the material from the filtering surface carried out by using air blown from a slit and it is followed by a phase of washing of the filtering surface, carried out by a plurality of sprayers.

Abstract: A method for recovering crystals from a slurry by supplying the slurry to a rotary sucking filter while rotating a cylindrical filter medium thereof to effect a sequence of operations of sucking filtration, washing and further sucking filtration, which method comprises conducting a sucking filtration while pressurizing the slurry side so as to maintain such a temperature and pressure that the filtrate of the rotary sucking filter will not reach a condition of supersaturation, whereby stuffing of the filter medium due to deposition of crystals from the mother liquor with increase in the slurry viscosity is prevented and the recovery of the crystals are realized efficiently over a long period of time. This method is suitable for recovering crude and purified crystals of terephthalic acid and can be applied also for the recovery of general crystilline products, such as hydroquinone, resorcin and so on from slurries of them.

Abstract: Method and equipment for filtration of a suspension so that the suspension to be filtered is fed from a feed part (4) onto the filter face of a filter member (5), which moves relative the feed part. The pulp layer is formed on the outer face of the filter member and the filtrate flows into the interior of the filter member, and the pulp layer is removed from the filter member at the removing point. After the pulp removing point (17), before the feed point (4), one or several cleaning points (12) are provided wherein liquid is made to flow through the filter member (5) from the inner face of the filter member to the outer face. The flow rate of the liquid that flows through the cleaning point or points is adjusted higher than the rate of any liquid flow that may flow through the rest of the filter member from the inside-face side to the outside-face side.
