Scope Notes

Glossary: Filtration The separation of a fluid-solid mixture, involving passage of most of the fluid through a porous barrier which retains most of the solid particulates contained in the mixture; includes straining solids from fluids. Filter medium filter media A porous barrier or porous arrangement of material, which lets a fluid pass while retaining most of the solids which were mixed with it. Filtering element filtering elements A section of filter medium in addition to parts to which the medium is demountably or permanently fixed, including other sections of medium, end caps, peripheral frames or edge strips, but excluding housings. Filter housing The fluid-constraining impervious vessel, whether open or closed, which contains, or is adapted to contain one or more filtering elements or filter media. Filter chamber filter chambers The space within a housing where filtering elements or filter media are located; partitions may divide a single housing into a plurality of chambers. Filtering apparatus Filtering elements combined with housings, cleaning arrangements, motor or like parts, which are characteristic of the particular type of apparatus. Ancillary devices such as pumps or valves are considered part of a filtering apparatus when inside the apparatus. Ancillary devices performing similar or different unit operations such as comminutors, mixers or non-filtering separators, whether or not inside the apparatus, are not considered part of a filtering apparatus. The term does not extend to apparatus, e.g. washing machines, of which the filter forms only a part. | Limiting references: Separating solids from solids by wet methods , Separating solids from solids using liquids or using pneumatic jigs or tables Magnetic or electrostatic separation of solid materials from solid materials or fluids, separation by high-voltage electric fields Flotation, differential sedimentation Separating solids from solids by dry methods, e.g. sieving, screening, sifting or using gas currents Centrifuges Vortex apparatus, e.g. cyclones Presses per se for squeezing-out liquid from liquid-containing material Making single crystals Into single crystals Manufacture of hollow fibres , Separation of difficult-to-condense gases or air by liquefaction Condensers | Application references: Blood or infusion liquid filters Screens or sieves per se Extrusion filters Filtering spinning solution or melt Filtration of lubricants Suction cleaner filters Filters for breathing-protection purposes Filtering air for vehicles Separating pneumatically-conveyed materials from propelling gas Exhaust or silencing apparatus for machines or engines having means for removing solid constituents of exhaust Air cleaners for the intakes of gas-turbine or jet-propulsion plants Air cleaners for the intakes of combustion engines Filters for liquid fuel specially adapted for, or arranged on, internal-combustion engines Air cleaners for the intakes of compressors Filtering in air-conditioning , Arrangement or mounting of filters in air-conditioning, air-humidification or ventilation Purification or separation of nitrogen Working-up unidentified gaseous mixtures obtained by cracking hydrocarbon oils Cleaning coal gas Working-up of natural gas, or synthetic natural gas Investigating materials Treatment of milk by dialysis, reverse osmosis or ultrafiltration Treatment of milk by electrodialysis Artificial kidneys Treatment of water e.g. softening of water by ion-exchange , Treatment of water by dialysis, osmosis or reverse osmosis Treatment of water by electrodialysis Apparatus for enzymology or microbiology with dialysis means Production or purification of sugar juices, e.g. by osmosis Extraction of sugar from molasses, e.g. by osmosis Diaphragms for electrolysis , Osmosis as energy source
