A filtration device includes in a pressure vessel a driven rotary shaft having a longitudinal bore. Fluid suspension to be processed to recover the fluid is expelled from distributing conduit, situated either in the shaft or in the vessel, the outlets of which open to the cavity of the pressure vessel at central processing zones proximate the shaft adjacent the radially inward portions of annular filtration discs secured to the shaft. The filtration discs are laminates in which an inner conducting support layer is enclosed by an outer filtration layer. The layers are porous, the pores are in fluidic communication, and the pores of the inner layer are larger than the pores in the outer layer. Fluid collecting in the outer layer of a spinning filter disc flows from the inner layer through collecting passageways to the longitudinal bore in the shaft, and is removed from the vessel through a conduit fluidly communicating with longitudinal bore.

Rotary filtration device

A filtration device includes in a pressure vessel a driven rotary shaft having a longitudinal bore into which fluid suspension to be processed to recover the fluid is pumped. The suspension is expelled into a processing zone in the vessel from distributing passages fluidly communicating the bore to the cavity of the pressure vessel. The processing zone is adjacent filtration discs affixed to the rotating shaft. The filtration plates are laminates in which an inner conducting support layer is enclosed by an outer filtration layer, the layers being porous, the pores being in fluidic communication, and the pores of the inner layer being larger than the pores in the outer layer. Fluid collecting in the outer layer of a spinning filter disc flows from the inner layer through collecting passageways to a second longitudinal bore in the shaft, and is removed from the vessel through a conduit fluidly communicating with such second longitudinal bore.
