Homemade reverse osmosis filter

Updated April 17, 2017

Reverse osmosis water treatment is a method of creating clean fresh water. It is recognised as a viable alternative to other water treatments, and reverse osmosis systems are produced for home use. Most homemade reverse osmosis systems are small enough sit under your kitchen sink.

Process

Water treated with a reverse osmosis process is treated in three steps: pre-filtration, processing through the membrane and holding. Pre-filtration removes the biggest particles and impurities in the water. Water is then passed, under pressure, through the fine reverse osmosis membrane, which creates solution fresh water on one side of the membrane and a saline solution on the other. This membrane also removes lead, manganese, iron, calcium, fluoride and other contaminants with larger molecules. Lastly, purified water is stored in a holding container for future use.

Homemade Systems

Most capable homeowners can install an under-sink unit to purify drinking water at the faucet. More complex whole home systems require professional installation.

Benefits

Reverse osmosis systems can improve your quality of life by supporting healthy living. The reverse osmosis process removes and disposes of water impurities like bacteria, salts, dissolved matter, detrimental minerals and heavy metals, which results in better tasting and healthier drinking water.
