Question

Do you find any role of osmosis in water purification?​

Answer 1

Answer:

Water purification systems usually employ the simple process of reverse osmosis to filter out impurities and undesirable components. Reverse osmosis, to put it simply, occurs when solvent molecules move from a region of lower concentration to a region of higher concentration, against the concentration gradient.

Answer 2

Answer:

Reverse osmosis (RO) is a technique of [water purification] used to remove ions, unwanted molecules and large particles from drinking water.A [semipermeable membrane] is used for this. To get reverse osmosis, an external pressure has to be applied in the opposite direction of [osmotic pressure].
