Title:
PROCESSES AND FILTERS FOR DESALINATION OF WATER
Document Type and Number:
WIPO Patent Application WO/2013/165996
Kind Code:
A3
Abstract:
In a process for the desalination of water, an impure, salt-containing water feed is passed through one or more filter media to remove from the feed impurities having a particle size greater than 50 µm and produce a first filtered water stream. The first filtered water stream is then passed through at least one further filter having an average pore size of 1 µm to 60 µm produced from sintered polyethylene particles having a molecular weight of at least 4 x 105 g/mol as determined by ASTM-D 4020 to remove at least a portion of the impurities having a particle size less than or equal to 50 µm from the first filtered water stream and produce a second filtered water stream. The second filtered water stream is passed directly to a reverse osmosis membrane to produce a purified water stream.
