Abstract: Filtration apparatus comprises in a housing an annular filtration chamber into which there is admitted a suspension under pressure and which is formed between an external filtration surface in the form of a body of revolution and an internal filtration surface which is housed therein and is in the form of a body of revolution also; the annular filtration chamber has a suspension inlet at one of the chamber ends and has at its other and a product outlet; the filtration surfaces are connected in each case to a filtrate discharge collector; a rotating mixing-agitating device is arranged in the annular filtration chamber.

Abstract: Filtration apparatus comprising in a housing an annular filtration chamber which is supplied with a suspension under pressure. The chamber is bounded between an external and an internal surface both of them in a form of a body of revolution, at least one of them being formed as a filtering surface and in the case connected to a filtrate discharge collector. At least one of the surfaces is capable of rotating. The chamber is connected at one end to a suspension inlet and on its other end to a product outlet. The surfaces bounding the filtration chamber are arranged eccentrically relatively to one another whereby a sufficient passage for the product is left free between the surfaces even in the narrowest figure of the eccentrical profil of the filtering chamber.
