Please give me answer fast.
I don't understand this question.
1. REVERSE OSMOSIS: A WATER PURIFICATION TECHNIQUE
Increased level of water pollutants is leading to contamination of water. So Reverse Osmosis is generally used to purify water these days. Find out more about the process and, prepare an attractive report on colorful A4 sheets (5 to 6 pages). Systematically record your findings, covering the following points
i. What is reverse osmosis?
ii. How does the reverse osmosis works?
iii. A well labeled diagram of reverse osmosis.
iv. Comparison of mineral water and reverse osmosis.
v. Images of Reverse osmosis plant.
Dear Student
Reverse osmosis is a process by which a solvent passes through a porous membrane in the direction opposite to that for natural osmosis when subjected to a hydrostatic pressure greater than the osmotic pressure.
For rest answer try to find out yourself as it is project based questions.

Reverse osmosis is a process by which a solvent passes through a porous membrane in the direction opposite to that for natural osmosis when subjected to a hydrostatic pressure greater than the osmotic pressure.
Molecules are forced through a semi-permeable membrane to form a less concentrated solution. Essentially, the membrane acts like a type of filter as it has extremely tiny pores that help remove microscopic contaminants from the water you drink by straining them out.
In the case of reverse osmosis drinking water systems, the semi-permeable membrane only lets water molecules through while other contaminants are collected and flushed away.
