Fluid Flow Distribution Device
First Claim
1. A membrane filtration module comprising:
- a membrane module comprising a plurality of permeable hollow membranes; and
a fluid distribution device;
adapted to removably surround at least a portion of the membranes of the membrane module, defining a plurality of through-hole openings for distributing a fluid, and adapted to distribute a flow of the fluid along a surface of the permeable hollow membranes.

Abstract
In a first membrane filtration module comprises a membrane module comprising a plurality of permeable hollow membranes; a fluid distribution device adapted to removably surround at least a portion of the membranes of the membrane module, the fluid distribution device comprising a plurality of through-hole openings for distributing a fluid, and the fluid distribution device adapted to distribute a flow of fluid along a surface of the permeable hollow membranes. In a second membrane filtration device comprises a membrane module comprising a plurality of permeable hollow membranes, each of the permeable hollow membranes having a surface; and a gas distribution device: adapted to distribute gas bubbles to the surface of the permeable hollow membrane, adapted to removably surround at least a portion of the plurality of permeable hollow membranes, and defining a plurality of through openings for distributing the gas bubbles to the membranes.

3. A filtration system for removing fine solids from a liquid suspension comprising:
-
a vessel adapted to contain the liquid suspension; a plurality of permeable, hollow membranes positioned within the vessel; a first system adapted to provide a pressure differential across walls of the membranes, wherein some of the liquid suspension passes through the walls of the membranes to be drawn off as permeate; a second system adapted to withdraw permeate from the membranes; and a fluid distribution device for distributing a flow of fluid along the surfaces of the permeable, hollow membranes, the fluid distribution device adapted to removably surround at least a portion of the membranes, and defining a number of through openings for distributing the fluid. - View Dependent Claims (4, 5, 6, 7, 8, 9, 10, 11, 12)
