Reverse osmosis is a technique used to generate fresh drinking water (no solutes) from a water source that contains many large molecules and dissolved ions. Reverse osmosis water purification systems use a selectively permeable membrane and a mechanical pump that create pressures against the water source. 1. Explain how reverse osmosis is similar to active transport. Use the principles demonstrated in the exercises to explain why reverse osmosis is an effective method for purifying water.
