    Abstract: The present invention involves a process for removing water from mixtures of alcohols and water by contacting such a mixture with an ion exchange resin of either the cation or anion type. Prior to use for alcohol dehydration, the ion exchange resin itself is dehydrated if necessary or desired by contacting it with methanol, propanol, isopropanol, acetone or other like low molecular weight hydrophilic solvents. After use for alcohol dehydration, the ion exchange resin is regenerated by contacting it with these regenerating agents.

    Abstract: A system for rapidly dewatering sludge in large quantities makes use of a filter plate that is capable of supporting heavy mechanized removal equipment without damage to the filter plate. The filter plate is monolithic and includes granular filter material that is rigidified and bonded together. In the disclosed process, sludge is pretreated with a polymer coagulant that breaks up solids and flocculates the sludge particles. The flocculated sludge is then spread on a bed of filter plates. As the bed is being filled, the large coagulated sludge particles settle and water is drawn off by gravity. A vacuum is then applied to the bed and the sludge is rapidly dewatered. Upon completion of dewatering, front end loading equipment may be used to remove the dried sludge cake from the bed.

    Abstract: A process is described for removing low density and very low density lipoproteins from blood plasma or serum and recovering the plasma or serum in a physiologically acceptable form. The method involves in a preferred embodiment passing plasma or serum through a cationic ion exchanger equilibrated with a physiologically acceptable saline solution. The ion exchanger is a water insoluble hydrophilic, water swellable cross-linked regenerated or microgranular cellulose matrix substituted with hydroxy C.sub.2 -C.sub.4 alkyl group. The ion exchanger capacity is provided by sulphate groups substituted with from 2 to 6 meq/g. The take up of low density lipoproteins is enhanced by recycling the plasma through the column.
