Reverse Osmosis Provides Superior Water Filtration

Reverse osmosis filtration system is used to treat ocean water, waste-water, and even brackish, cloudy well water, to make them fit for human consumption. This water purifying system is one of the most advanced on the planet and is completely safe.

A good example of osmosis is the swelling of potatoes after you soak them in distilled water for some time. This indicates that the potatoes have absorbed the water, in a natural attempt to achieve a balance of water molecules in the potatoes and the distilled water outside. Reverse osmosis works the other way. It releases water molecules from a dense solution or source. However, reverse osmosis does not happen naturally. It needs applied pressure to push water molecules out of the dense solution.

Reverse osmosis filtration is the forced pressurized movement of water molecules from a dense solution, such as salty or contaminated water, through a special cleansing membrane, in order to remove unwanted minerals, and contaminants like harmful chemicals, bacteria and viruses. Pressure is applied onto sea water, waste water or well water such that it is forced through the membrane, which then allows only molecules the size of water or smaller to pass through. The membrane rejects contaminants with particles bigger than water molecules.

The true beauty of the reverse osmosis filtration system is its simplicity. Unlike other water filtration systems, no harsh chemicals are required. Double pass reverse osmosis allows for multiple cleansing, while nanofiltration membrane systems can remove the tiniest contaminants. The system may also be scaled up or down to suit different needs, from large industries to households.
