1.	Pore size Nano-filtration membrane ranges from __________(a) 0.1- 5µm(b) 0.1- 0.01µm(c) 0.001- 0.01µm(d) 0.0001- 0.001µmThe question was posed to me by my college director while I was bunking the class.This interesting question is from Membrane Filter in portion Building Blocks of Dairy Processing of Dairy Engineering
Answer» The CORRECT answer is (C) 0.001- 0.01µm Explanation: Nanofiltration has a pore size range of 0.001-0.01um. NF membranes can filter particles up to and INCLUDING some salts, synthetic dies and sugars, however it is unable to remove most aqueous salts and metallic IONS, as such, NF is generally confined to specialist uses.
