Abstract

The present invention provides apparatus and methods for membrane filtration of water by passing the water through a housing (9) having an inlet (5) and an outlet (6) and defining a flow path for water therethrough, a membrane filter being located within the housing and the flow path extending through said membrane filter and at least part of the flow path, downstream of said membrane filter, extending downwardly, in a downstream direction, at an angle of from 1° to 10° to the horizontal.

Claims (17)

1. Apparatus for water treatment comprising a housing having an inlet and an outlet and defining a flow path for water therethrough, a membrane filter being located within the housing and the flow path extending through said membrane filter and at least part of the flow path, downstream of said membrane filter, extending downwardly, in a downstream direction, at an angle of from 1 ° to 10° to the horizontal.
2. Apparatus according to Claim 1 , wherein said angle is from 2° to 5° .
3. Apparatus according to Claim 1 or Claim 2, wherein said angle is 2°.
4. Apparatus according to any of the preceding claims, wherein said housing is substantially cylindrical and the flow path extends along the longitudinal axis of the housing.
5. Apparatus according to any of the preceding claims, wherein the membrane filter is provided within a cartridge.
6. Apparatus according to any of the preceding claims, wherein the apparatus comprises a plurality of said housings and the flow path extends in series through each of them.
7. Apparatus according to Claim 6, wherein the apparatus comprises four of said housings.
8. Apparatus according to any of the preceding claims, wherein the or each housing is attached to a metal plate.
9. Apparatus according to Claim 8, wherein the plate is a stainless steel plate which forms the front wall of the apparatus and comprises one or more machined circular holes providing access to the or each housing and further comprises at least one water pressure gauge.
10. Apparatus according to Claim 9, wherein the or each circular hole is covered by a clamped circular cap cover that is provided with a handle and a tube-like projection on its inner side for locking engagement with a membrane carrying unit within the housing.
11. Apparatus according to any of Claims 8 to 10, wherein the housings are locked into the plate in a configuration in which two housings are placed side-by-side and below two other side-by-side placed housings.
12. Apparatus according to Claim 11 , wherein the housings are interconnected by tubes, gaskets and flange faces so as to cause the water to flow in a sequence starting from the bottom left housing, then to the bottom right housing, or vice versa, then to the top right housing, then to top left housing, or vice versa, and then exiting via the outlet tube. IB.
Apparatus according to any of the preceding claims, wherein the inlet feed water is caused to flow into the apparatus by an external pump causing a 2 Bar differential pressure.
14. Apparatus according to any of the preceding claims, wherein the apparatus has a footprint of approximately 588cm (width) x 504cm (length) x 600cm (height), a weight of about 70kg and is made from food grade materials.
15. Apparatus according to any of the preceding claims, wherein the pump is configured to cause water to flow through the apparatus at a flow rate of from 20- 40 litres/min.
16. Apparatus according to any of the preceding claims, wherein a plurality of such apparatuses are arranged in a configuration and connected to external pipework via a manifold to treat inlet feed water at flow rates higher than 40 litres/min.
17. A method of treating water comprising passing the water through a housing having an inlet and an outlet and defining a flow path for water therethrough, a membrane filter being located within the housing and the flow path extending through said membrane filter and at least part of the flow path, downstream of said membrane filter, extending downwardly, in a downstream direction, at an angle of from 1° to 10° to the horizontal.
