Figure 5: Mineral harvest data from wide pore ultrafiltration experiments. Ultrafiltration permeates obtained from milk protein concentrate manufacturing process were concentrated to 11% solids in reverse osmosis unit. Control is the feed that has normal level of minerals, High mineral is the feed that has higher mineral content. PES 20 is Polyether sulfone membrane with 20 kDa molecular weight cut off. PVDF 30 and 40 are Polyvinyledene membranes with 30 and 40 kDa molecular weight cut off.
