Osmotic Pressure Calculator (Van t Hoff Equation) — Frequently Asked Questions
Q1 What is reverse osmosis (RO)? ▾
If applied mechanical pressure exceeds the natural osmotic pressure of a solution, solvent molecules are forced backward through the membrane against the concentration gradient, purifying water.
