1.	Which of the following mechanisms is used by a membrane filter to remove particulate material from the water?(a) Adsorption(b) Settling(c) Straining(d) CrystallizationThis question was addressed to me in my homework.The question is from Membrane Filter in chapter Building Blocks of Dairy Processing of Dairy Engineering
Answer» The correct OPTION is (c) Straining To elaborate: Straining has been identified as the principal mechanism that is operative in the removal of suspended SOLIDS during the filtration of SETTLED secondary effluent from BIOLOGICAL TREATMENT processes. Other mechanisms like interception and adhesion are also operative even though their effects are small and, for the most part, masked by the straining action.
