Abstract
(EN)
The invention relates to the process of liquids purification from suspended particles and to the filters for the implementation of the process (variants). The object of the invention is use of ecologically clean material and as a tail receipt of ecologically clean production particularly in food industry as well as the possibility of multiple use of filtration material. The another object of invention is to draw up filters with comparatively large ability of dirt absorption which can be used in food industry. The above mentioned object is executed by filtration of liquid through tuff using of the cartridge filter type, so depending on content, volumes and purification level of liquids to be filtered the cartridge filters are used which have filtration element made of tuff fragment or tuff reduced fragments placed in framework consisting of internal and external nets.

Procédé de purification de liquides par filtrage de particules en suspension et filtres permettant de mettre en oeuvre ledit procédé (variantes). Un objet de la présente invention est l'utilisation de matière écologiquement propre et comme résultat, l'obtention d'un produit écologiquement propre, en particulier dans les industries alimentaires, ainsi que la possibilité d'une utilisation multiple de la matière de filtrage. Un autre objet de la présente invention est la conception de filtres, ayant une capacité comparativement élevée d'absorption de la poussière, qui peuvent être utilisés dans les industries alimentaires. A cet effet, le filtrage de liquide est effectué à travers du tuf à l'aide de filtres de type à cartouche. Ainsi, selon le contenu, les volumes et le niveau de purification souhaité des liquides à filtrer, on utilise des filtres à cartouche dont l'élément filtrant est constitué de fragments de tuf ou de fragments réduits de tuf placés dans une enveloppe constituée de filets interne et externe.
