Abstract

1324031 Dialysis HYDRONAUTICS-ISRAEL Ltd 17 Sept 1970 44398/70 Heading B1X A solution is concentrated by forcing it through two membranes in series or two groups of membranes in series with the first membrane having a higher rejection rate in the process than the second. The product is that liquid which does not pass through the second membrane.
