Solar System Models

Reverse Osmosis

Reverse osmosis is based on the process of osmosis. Osmosis involves the selective movement of water from one side of a membrane to the other. Reverse osmosis is also known as hyper filtration. It is the same process as used by a human body to filter out contaminants. Particles or impurities can be removed from a solution through the process of reverse osmosis. The solution is passed through a semi-permeable membrane. The semi permeable membrane allows the passage of water but rejects ions like sodium and calcium or contaminants like bacteria or urea. Gore-tex is a common semi permeable membrane. Gore-tex fabric contains an extremely thin plastic film into which billions of small pores have been cut. The pores are big enough to let water vapor through, but small enough to prevent liquid water from passing through.

The Kyoto Accord and What It Means
