a) Membrane separation follows the law of conservation of energy
b) Membranes are used for separating components in food on a molecular basis
c) Membrane separation cannot be used in ultrafiltration of blood proteins
d) Reverse osmosis is an important application in membrane separation

Answer: c
Explanation: Membrane separation follows the law of conservation of mass and energy. The membrane separation is used to separate gaseous and liquid streams. It is also used in ultrafiltration for concentrating solutions of large polymetric molecules like blood proteins and milk molecules.Reverse osmosis is a water treatment where sufficient pressure applied against the water to force it through a semi permeable membrane, the water molecules are separated from other constituents within the water.
