Abstract

Embodiments of the present invention seek to provide a membrane distillation system having compact design and simplified connection system for fluid flow paths used in the system. According to one aspect, a membrane distillation system includes at least one membrane module and at least one like configured heat exchanger module, the modules being supported and connected to like configured manifold devices for providing fluid communication between said modules.

Claims

1. A membrane distillation system comprising at least one membrane module and at least one like configured heat exchanger module, wherein the modules are supported and connected to like configured manifold devices for providing fluid communication between said modules.

2. A system according to claim 1 further comprising a hot heat exchange module for transferring heated fluid to the membrane module and a cold heat exchange module for cooling fluid from the membrane module.

3. A system according to claim 2 wherein the heated fluid is provided to a feed side of the membrane module and the fluid to be cooled is provided from a permeate side of the membrane module.

4. A system according to claim 1 wherein each manifold device defines a number of fluid communication channels opening into fluid communication ports, wherein the fluid communications ports of one or more manifold devices are in fluid communication with fluid communication ports of one or more other manifold devices to provide for fluid flow therebetween.

5. A system according to claim 1 wherein one or more of the manifold devices include respective insulation layers.

6. A system according to claim 5 wherein the insulation layers are respectively disposed inside the fluid communication channels.

7. A system according to claim 1 wherein the manifold devices are block-like in shape and configuration.

8. A system according to claim 1 wherein the modules are arranged in a two dimensional array with like type modules provided in rows of the array.

9. A system according to claim 1 wherein the modules extend between a pair of associated manifold devices.

10. A system according to claim 1 wherein the modules extend generally vertically between upper and lower manifold devices.

12. A system according claim 3 wherein each manifold device has a number of fluid communication channels opening into fluid communication ports, wherein the fluid communications ports of one or more manifold devices are in fluid communication with fluid communication ports of one or more other manifold devices to provide for fluid flow therebetween.

13. A system according to claim 4 wherein one or more of the manifold devices include respective insulation layers.

14. A system according to claim 6 wherein the manifold devices are block-like in shape and configuration.

15. A system according to claim 7 wherein the modules are arranged in a two dimensional array with like type modules provided in rows of the array.

16. A system according to claim 8 wherein the module extends between a pair of associated manifold devices.

17. A system according to claim 9 wherein the module extends generally vertically between upper and lower manifold devices.
