Abstract:
Ultrafiltration equipment was built for a ceramic membrane module with a filtration area of 0.15 m2. Additionally acquiring a 1.0 HP centrifugal pump, a 30 liter tank and a batch of one-inch diameter pipes, valves, instruments and accessories. The equipment was tested with water, obtaining a flux of 120 x10-6 m/s, at 240 kPa and on a 100 kDa membrane, while with an 8 kDa membrane the flux was 50 x10-6 m/s at the same pressure.. When tested with whole milk, the fluxes were 5 x10-6 and 3 x10-6 m/s for the 100 and 8 kDa membranes, respectively, at the pressure of 240 kPa. Whole milk was concentrated five times on 8 and 100 kDa membrane and a total solids content of 50% was reached, equivalent to a protein content of 15 to 17%. It was found that it was better to use the 100 kDa membrane because it reduces the operation time by half.
