Abstract

To remove solids from a liquid such as sea water, the liquid is pumped into a membrane filter module, which may be of the cross-flow type, a pulsating flow being imposed on the liquid upstream of the filter by means of a rotating ball valve in series with a centrifugal pump, thereby reducing clogging of the filter membrane. The effect may be enhanced by providing the membrane with a grooved upstream surface, inducing local vortex mixing. Sea water so filtered may be deaerated and then pumped into oil-bearing rocks to displace the oil. <IMAGE>
