The need for whey protein is growing and will do so for the next decade. The dairy industry needs a reliable, sustainable, cost-efficient solution to obtain native whey protein from skimmed milk and to separate it from casein protein. 
To meet these challenges, Pentair hollow fiber membrane systems are the ultimate choice. Our straw-like membranes are manufactured from poly ether sulphon, a polymer known for its excellent properties regarding food contact and chemical and high-temperature compatibility.

how does it work?

Pentair Dairy Membrane Systems include hollow fibers. They are hygienically constructed in a membrane element with the optimal pore size and length. Multiple elements are manufactured in a membrane unit, and several membrane units are in a so-called cascade system. 

Pentair X-Flow hollow fiber technology provides outstanding performance in purity and recovery.
