Abstract
A process for treating waste water produced in a cheesemaking operation. The process comprises treating a milk product so as to form a curd, subjecting the curd to an elevated temperature while in contact with water and separating the curd from a water-containing material including milk fats. The process further includes subjecting the water-containing material to microfiltration in a microfilter so as to produce a concentrate rich in the milk fats and a permeate, and recovering the concentrate and the permeate.
