B01DSEPARATION separating solids from solids by wet methods B03B, B03D; by pneumatic jigs or tables B03B; by other dry methods B07; magnetic or electrostatic separation of solid materials from solid materials or fluids, separation by high-voltage electric fields B03C; centrifuges, vortex apparatus B04; presses per se for squeezing-out liquid from liquid-containing material B30B9/02; treatment of water C02F, e.g. softening by ion-exchange C02F1/42; arrangements of air intake cleaners in gas turbine plants F02C7/05 ; arrangements or mounting of filters in air-conditioning, air-humidification or ventilation F24F13/28 This subclass covers: evaporation, distillation, crystallisation, filtration, dust precipitation, gas cleaning, absorption, adsorption; similar processes which are not concerned with, or limited to, separation, except in the case of absorption or adsorption. In this subclass, the terms or expressions are used with the meaning indicated: "filtration" and analogous terms include straining solids from fluids. Filtration is a process that normally uses a filter medium; "filter medium" is a porous material or porous arrangement of material used to filter solids from fluids; "filtering element" is 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" is 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" is 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" consists of filtering elements combined with housings, cleaning arrangements, motor or the 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 operation 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. For apparatus used in drying or evaporation, class F26 takes precedence over this subclass. Group B01D59/00 takes precedence over the other groups of this subclass and over other subclasses in class B01. In this subclass, combination sets [C-Sets] are used.
