    摘要： Methods and apparatus for increasing the continuous filtering flow rate through a pressure liquid filter unit of liquid-to-be-filtered having (1) a carrier liquid, (2) coalescing solids particles which tend to adhere and bridge filter clement gaps sized substantially larger than said particles and (3) larger impurity elements to be filtered out of the liquid-to-be-filtered and sized larger than such filter element gap. A pressure liquid filter unit containing a filter element having gaps, a given gap being sized to reliably pass the carrier liquid and coalescing solids particles at a first relatively low liquid flow rate, but blocking coalescing solids particles passage therethrough due to bridging of said gaps by the coalescing solids particles at a relatively high liquid flow rate. The coalescing solids particles adjacent said gap are agitated at an ultrasonic frequency, thereby passing the carrier liquid and coalescing solids praticles through the gap at the relatively high flow rate without bridging and blinding of the gap by the coalescing solids particles.

    摘要： An ultra-fine coal particle fraction forms a coal product with particles that are dilatant due to the mechanical stripping of the clay contaminates from the coal surface and the subdividing of the clay to clay platelets which are peptized to maintain discreetness in an aqueous slurry. The coal particles are unflocculated and can produce an aqueously permeable barrier on a sieve. The ultrafine coal product has an increase of 100-150 BTU per pound and when combusted reduced Nox production of 20-40% is realized. In a 15.times.0 micron coal fraction, the sulphur content is significantly reduced.

    摘要： A continuous microfiltration machine for removing suspended solid particles from process and waste water comprises a container (2) with an inlet conduit (4) defining a flow direction (F), and having therein an influent chamber (7) for feeding the liquid to be filtered, a treatment chamber (8) with a bottom wall (9), at least one pair of filter disks (10) keyed to a shaft (12) perpendicular to the flow direction (F) and having inner filter surfaces (10′) outer surfaces (10″) and outer peripheral edges (15) in sliding contact with the bottom wall (9), an effluent chamber (17) for receiving the filtered liquid, with a discharge conduit (18), drive means (13, 14) for imparting rotation to the disks, first jet washing means (20) directed against the outer surfaces (10″) of the disks (10) for removing the particles retained thereby, a first collecting duct (24) for collecting the removed particles, which is interposed between the disks (10) and has substantially parallel side edges (25) located at a predetermined minimum distance (D) from the inner surfaces (10′) of the disks (10). The inner surfaces (10′) of the disks are substantially flat and continuous surfaces, with a flatness error (ε) smaller than said predetermined minimum distance (D).

    摘要： A fluid classifier for separating particles from a lading for operation with a lading tank including a filter unit for mounting in the tank and having capillary passages for fluid flow from the tank externally of the filter unit to the interior of the filter unit for providing a pressure differential across the capillary passages resulting from a difference in fluid level in the tank and within the filter unit, a drive for rotating the filter unit in the tank, and a pump for pumping fluid from filter unit interior to the outlet. Ultrasonic transducers positioned along the filter unit for agitating the lading adjacent the capillary passages. A method of controlling fluid flow through the capillary passages.
