    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.

    Abstract translation: 在用于脱盐水的方法中,使不纯的含盐水进料通过一个或多个过滤介质以从进料中除去粒度大于50μm的杂质,并产生第一过滤水流。 然后将第一过滤水流通过至少一个平均孔径为1μm至60μm的另外的过滤器,该过滤器由ASTM-D 4020测定的具有至少4×10 5 g / mol的分子量的烧结聚乙烯颗粒产生 从第一过滤水流中除去粒度小于或等于50μm的至少一部分杂质,并产生第二过滤水流。 将第二过滤水流直接通入反渗透膜以产生纯化水流。
