Method for filtering and recovering solids from potato process water

摘要

A method for filtering and recovering solids from potato process water that results in a product containing a portion of the solids from the potato process water is presented. In general, the method involves providing a plurality of vessels wherein a step in a manufacturing process takes place in each vessel and wherein at least one step in the manufacturing process produces a potato process water having solids. The potato process water is passed through at least one ultrafilter wherein each ultrafilter produces an ultrafilter (u/f) permeate stream and a u/f concentrate stream. The u/f concentrate stream is collected and reintroduced into at least one vessel in the manufacturing process producing a product containing a portion of the solids from the potato process water. The final characteristics of the product remain essentially unchanged.
