Abstract
A filtration unit for purifying or treating fluid that includes one or more membrane units having a permeate section. The permeate section of the membrane units is fed fluid that passes through a sealing insert having a fluid inlet and a passage that discharges in fluid communication with the permeate section. The sealing insert is arranged in a support frame of the membrane unit to form a fluid channel for delivering fluid through the insert and along an outer perimeter surface that maintains performance of the membrane unit during operation.
Claims23
A filtration unit comprising:
- a. a membrane unit comprising a membrane sheet, the membrane sheet having a first surface;
- and
- b. a spacer block comprising an aeration opening and an aeration guide system in fluid communication with the aeration opening, the aeration guide system comprising a plurality of aeration guides for directing gas to multiple locations on the first surface of the membrane sheet the plurality of aeration guides comprising a primary aeration guide and a secondary aeration guide extending from the primary aeration guide,
- wherein the aeration guide system is positioned against the membrane unit.
A membrane sheet scouring unit comprising an aeration guide system positioned adjacent a first surface of the membrane sheet, the aeration guide system comprising a plurality of aeration guides for directing a scouring gas to multiple locations on the first surface of the membrane sheet, the plurality of aeration guides comprising a primary aeration guide and a secondary aeration guide extending from the primary aeration guide, the secondary aeration guide comprising an outlet at the first surface of the membrane sheet.
A filtration unit comprising:
- a. a membrane unit comprising a permeate inlet for introducing fluid into a permeate section of the membrane unit;
- and
- b. a sealing insert comprising a fluid inlet, a passage radially extending from the fluid inlet and the passage having a passage fluid outlet, and an outer perimeter surface comprising a fluid channel extending around the entire outer perimeter surface of the sealing insert, the passage fluid outlet of the sealing insert and the fluid channel of the outer perimeter surface of the sealing insert being in fluid communication with the permeate inlet of the membrane unit.
A filtration unit comprising
- a. a membrane unit comprising a permeate chamber, the permeate chamber comprising an chamber inlet;
- and
- b. a sealing insert in fluid communication with the chamber inlet of the permeate chamber of the membrane unit, the sealing insert being a ring structure comprising a fluid inlet defined by an inner circular surface, a fluid outlet, and an outer circular perimeter surface, the outer circular perimeter surface comprising a fluid channel extending around the entire outer circular perimeter surface, wherein the fluid channel on the outer perimeter surface of the sealing insert is open to the permeate chamber of the membrane unit.
