Abstract

An apparatus for filtering water containing particles of impurities includes a chamber 10 containing layers 20, 21, 22, 23 of filter material. An inlet passage 15 communicates with distributors 16, 17. An outlet passage 18 communicates with collector pipes 19 lying within the bottom layer 20 of filter material. The height of a material-free zone 24 between the layer and the distributors 16, 17 is not greater than the combined thickness of the layers 20, 21, 22, 23 and is preferably not greater than half this thickness. The filtration process includes backflushing the filter material at intervals to remove accumulated impurities, and according to one aspect of the invention backflushing is carried out using unfiltered water. The apparatus and process enable equipment of less size and weight than has previously been considered feasible to supply a given quantity of filtered water, the reduced size and weight being particularly advantageous for the filtration of seawater on offshore oil platform. <IMAGE>
