ANORDNING FOR VATTENAVSALTNING GENOM OMVEND OSMOS

摘要

Apparatus for desalinating water by reverse osmosis, having a series of porous discs each covered on both sides by a membrane, and compressed at their edges between respective pairs of a stack of module plates which are identical and which each consist of two mirror image halves, alternate module plates in the stack being rotated through 180 DEG . A zig-zag flow path through the stack is thereby provided with desalinated water passing by reverse osmosis into the porous discs and hence radially outward of the stack for collection.
