FILTRATION MODULE INCORPORATING CAPILLARY MEMBRANES Russian patent published in 2014 - IPC B01D63/02 C02F1/44 

FIELD: process engineering.

SUBSTANCE: invention relates to "from outside-to inside" filtration modules including capillary membranes intended for water or other turbid fluid treatment. Proposed device comprises membrane shutters, each being formed by one row of capillary membranes, lower manifold arranged nearby lower end of membrane shutters and connected therewith, and at least one membrane shutter. Appropriate top manifold arranged nearby upper end of membrane shutter and connected with its capillary membranes is arranged for every membrane shutter. Membrane shutters are arranged vertically while top manifolds are spaced apart to allow fluid flowing upward between membrane shutters and top manifolds. Top manifolds of at least two adjacent membrane shutters are located at different height while capillary membranes of adjacent shutters feature different length.

EFFECT: lower turbulence, lower life and/or material fatigue in filtration module.
