Membrane filtration is widely used in the dairy industry. This chapter provides an overview of the various applications of reverse osmosis, nanofiltration, ultrafiltration, and microfiltration in the processing of milk, and dairy waste streams. A summary of milk composition and chemistry is provided in relation to membrane processing. Applications of membrane filtration in milk processing are then discussed, including on-farm concentration of milk, removal of microorganisms, and fractionation of protein and fat. Coverage also includes the use of membranes for standardizing the composition of cheese milk, processing and concentration of whey and whey proteins, and purification and treatment of dairy wastes. Recent progress in the understanding of flux decline and fouling in dairy membrane filtration is outlined, along with the potential application of ultrasound.
