Frame system for membrane filtration modules
View Patent ↗A module arrangement ( 5 ) according to an embodiment of the invention consists of a plurality of membrane modules ( 6 ) arranged in a two dimensional array ( 7 ) and extending between upper and lower block-type manifolds ( 8 ) and ( 9 ), respectively. The array of modules is further divided into sub-groups of modules ( 10 ) separated from each other by space ( 11 ) extending transversely across the membrane array ( 7 ). An integrated support frame ( 12 ) is positioned in the space ( 11 ) between the sub-groups ( 10 ) and is fixed to the upper and lower manifold blocks ( 8 ) and ( 9 ) to form an integrated support structure within the module array ( 7 ).
1. A filtration system comprising:
a plurality of membrane modules arranged in a membrane module array divided into membrane module array sub-groups by a spacing between numbers of modules within the membrane module array, the membrane modules extending between a first fluid communicating manifold and a second fluid communicating manifold; and
an integrated support member located within the spacing and including one of a first portion of the support member disposed in an aperture in the first fluid communicating manifold and a second portion of the support member disposed in an aperture in the second fluid communicating manifold, the integrated support member including:
an upper cross portion;
a base portion; and
a pair of vertically extending arms affixed between the upper cross portion and the base portion;
each of the upper cross portion, the base portion, and the pair of vertically extending arms including extended portions extending outside of a perimeter of a rectangle defined by the upper cross portion, the base portion, and the pair of vertically extending arms.
2. The system of claim 1 , wherein the support member is connected to at least one of the first fluid communicating manifold and the second fluid communicating manifold.
3. The system of claim 2 , wherein the first fluid communicating manifold and the second fluid communicating manifold comprise upper and lower manifolds and the membrane modules extend generally vertically therebetween.
4. The system of claim 2 , wherein a number of the support members are connected together to form a support structure.
5. The system of claim 1 , wherein the plurality of membrane modules comprise bundles of hollow fibre membranes.
6. The system of claim 1 , wherein the system is a pressurised membrane filtration system.
7. The system of claim 1 , wherein the system is a non-pressurised submersed membrane filtration system.
8. The system of claim 1 , wherein the integrated support member includes a first portion disposed in the aperture in the first fluid communicating manifold and a second portion disposed in the aperture in the second fluid communicating manifold.
9. The system of claim 1 , wherein the extended potions of the upper cross portion support longitudinal support rails coupled to the first fluid communicating manifold.
10. The system of claim 1 , wherein a base of each of the vertically extending arms include support flanges configured to fix the membrane module array to a support base.
11. The system of claim 1 , wherein the extended portion of the upper cross portion is affixed to a manifold pipe coupled to the first fluid communicating manifold, and the extended portion of the base portion is affixed to a manifold pipe coupled to the second fluid communicating manifold.
12. The system of claim 1 , further comprising a fluid conduit directly affixed to a manifold block located at an end of the spacing between the numbers of modules.
