1.	Which one of the following is the name of the process of reversing the direction of water flow through the filter using filtered water?(a) back pulse(b) reverse flow(c) air pressure(d) front pressureThe question was asked in unit test.My question is from Membrane Filter in chapter Building Blocks of Dairy Processing of Dairy Engineering
Answer» Right answer is (b) REVERSE flow Explanation: Applying an external pressure to reverse the natural flow of pure solvent, thus, is reverse OSMOSIS. The process is similar to other membrane TECHNOLOGY applications. However, key differences are found between reverse osmosis and filtration. The predominant REMOVAL mechanism in membrane filtration is straining, or size exclusion, so the process can theoretically ACHIEVE perfect efficiency regardless of parameters such as the solution’s pressure and concentration.
