Question

what is reverse osmosis​

Answer 1

Answer:

Reverse osmosis is a process of movement of solvent to the opposite direction of natural osmosis.

Explanation:

Reverse osmosis is a process of movement of a solvent through a semi-permeable membrane to the opposite direction of natural osmosis when subjected to hydrostatic pressure that greater than osmotic pressure. This technology is used for water purification treatment to remove a large number of contaminants from the water. It is commonly used in drinking water purification from seawater, removing salts and other effluent materials from drinking water. It also has a lot of other applications as in, food industry, low-alcohol beer, hydrogen productions, aquariums, window cleaning, etc.

Even though this has a lot of applications, there are several issues also. some of them are;

• They remove beneficial bacteria also while purifying water.

• The semi-permeable membranes can get clogged easily.

• It takes a lot of water for operation than during other filtration or purification process.

Answer 2

RO is a water purification process that uses a partially permeable membrane to remove ions, unwanted chemicals, and larger particles from drinking water.

• In reverse osmosis, an applied pressure is utilised to counteract osmotic pressure, a colligative property generated by chemical potential changes in the solvent, which is a thermodynamic parameter.
• Reverse osmosis can remove a variety of dissolved and suspended chemical species, as well as biological species, from water, and is used in both industrial and potable water production.
• As a result, the solute is trapped on the membrane's pressed side while the pure solvent goes through.
