Answer to Question #288378 in General Chemistry for Ali

Question

An aqueous solution of salts, macromolecules and microbes is

fed across a reverse osmosis membrane, an ultrafiltration

membrane and a microfiltration in that order. What do the three

permeates contain?

Answer 1

Reverse Osmosis is a technology that is used to remove a large majority of contaminants from water by pushing the water under pressure through a semi-permeable membrane.

Ultrafiltration (UF) is a variety of membrane filtration in which forces like pressure or concentration gradients lead to a separation through a semipermeable membrane.

Microfiltration is a pressure-driven process in which a membrane is applied to separate particles from an aqueous solution.
