ABSTRACT:
A membrane process for producing an improved product quality comprising feeding a clarified serum at an elevated pressure to a plurality of reverse osmosis units in two stages--the first having high-rejection polyamide membranes and the second having low-rejection membranes, wherein the permeate from the low-rejection membranes is recycled to the high-rejection feed.
