Square membrane manifold system
First Claim
1. A membrane module comprising:
- a first header having one or more openings formed therein;
a plurality of porous hollow membranes arranged in partitioned bundles, each of the porous hollow membranes extending between and being fixed at a first end in the first header and at a second end in a second header, the one or more openings formed in the first header positioned to coincide with spaces formed between the partitioned bundles; and
a headpiece sealingly connected to and in fluid communication with the second header, the headpiece comprising;
a filtrate conduit in fluid communication with open ends of said membranes for the withdrawal of filtrate therefrom; and
a gas conduit configured to communicate gas to the module through the one or more openings formed in the first header, the gas conduit in communication with a source of gas; and
a pipe or tube connected to the gas conduit of the headpiece positioned below the one or more openings formed in the first header.

Abstract
A membrane module (3) comprising a plurality of porous hollow membranes (8). The membranes (8) extend between and are fixed at each end in a header (5, 6). One header (6) has one or more of openings (12) formed therein. The openings (12) are in fluid communication with a source of gas and/or liquid (13, 14, 15). The other of the headers (5) is sealingly connected to and in fluid communication with a head-piece (9). The head-piece (9) is adapted to couple to an associated head-piece of a further module to form a rack of modules (17). A potting head (6) for use in mounting porous hollow membranes (8) is also disclosed comprising a preformed potting element (29). The potting element (29) includes one or more cavities (30) for receiving curate potting material which, in use, supports said membranes (8).

18. A membrane module rack comprising:
-
a plurality of membrane modules, each of the plurality of membrane modules including; a plurality of porous hollow membranes, the membranes arranged in partitioned bundles, the membranes extending between and fixed at each of a first and a second end in a header; a first header having one or more of openings formed therein, the openings positioned to coincide with spaces formed between the partitioned bundles, the openings in fluid communication with at least one of a source of gas and a source of liquid; a second header sealingly connected to and in fluid communication with a head-piece including a gas conduit configured to communicate gas to the module; a source of gas in communication with the gas conduit a pipe or tube connected to the gas conduit of the headpiece positioned below the one or more openings formed in the first header; the head-piece adapted to couple to an associated head-piece of a further module to form a rack of modules and to provide fluid communication between the gas conduit and a gas conduit of the further module; the plurality of membrane modules connected together by the headpieces. - View Dependent Claims (19, 20)

21. A filtration system comprising:
-
a rack of membrane modules, each of the membrane modules including; a plurality of porous hollow membranes arranged in partitioned bundles, the membranes extending between and being fixed at a first end in a first header and at a second end in a second header; the first header having one or more openings formed therein, the one or more openings positioned to coincide with spaces formed between the partitioned bundles, the one or more openings being in fluid communication with at least one of a source of gas and a source of liquid; a skirt provided below the first header; the second header sealingly connected to and in fluid communication with a head-piece, the headpiece including a filtrate conduit in fluid communication with open ends of the membranes and adapted to couple to an associated head-piece of a further module to form a rack of modules and to provide fluid communication between the filtrate conduit and a filtrate conduit of the further module; a gas conduit formed in the headpiece and in communication with a source of gas;
a pipe or tube connected to the gas conduit of the headpiece positioned below the one or more openings formed in the first header;wherein the modules are positioned vertically in a tank containing feed liquid to be filtered; and a source of suction configured to provide a transmembrane pressure to the membranes in the modules to cause filtrate to pass through pores in the membranes, the source of gas configured to at least one of continually or intermittently supply gas to the one or more openings so as to produce gas bubbles which move upwardly between the fibres to scour the outer surfaces thereof. - View Dependent Claims (22)
