A) Estimate the necessary ultrafiltration membrane area (m²) required to treat 1,000 mper day given a membrane porosity of 40%, membrane pore size of 0.3um, a net transmembrane pressure 150 kPa, a memberane thiickness of 1mm, and a water temperature of 10degree C. B) Compare and Contrast differences between ultrafilteration membranes and reverse osmosis membranes.
