Dairy processors are using Donaldson filters in their food quality and safety programs
Dairy processors are using Donaldson filters and tests in their food quality and safety programs. Process water and ingredient water are generally filtered down to 0.2 micron in order to remove bacteria and particulate. Before putting in a final membrane element to capture submicron particles, several stages of pre-filtration are recommended in order to ensure a long life of the membrane element. Donaldson offers a full line of coarse and pre-filtration down to a final membrane cartridge filter that is rated to 0.2 microns. The company also has a Filter Test Center for air, steam and liquid depth elements, and a Membra-Check Integrity Tester for membrane elements.
