Filter

The filter (French filtre, from late Latin Latin filtrum, it it is literally - felt) — the device in which by means of a filtering partition separation is carried out, a condensation or clarification of the non-uniform systems containing hard and liquid (gaseous) phase. Besides, as filters are called as devices and devices for clearing of solutions of mineral salts, separations on fraction of polymeric ions etc. with the help ionite, and also the devices passing either delaying acoustical or electromagnetic waves of certain frequencies (the Filter the acoustic, Electric filter, the Thermal filter, the Optical filter).

Filtering is a separation of suspensions or aerosols by means of filters - porous partitions (metal, asbestos, glass and others), passing a fluid or gas, but delaying hard particles.

Depending on an aspect of non-uniform system distinguish liquid filters (are intended for filtering of suspensions) and gas filters (for separation of aerosols and clearing gases. The elementary filter is the vessel disjointed on two parts by a filtering partition. Between filter parts the difference of pressure is created, under which operation a fluid (or gas) passes through a partition delaying hard particles.
