Regarding Reverse Osmosis


Bookmark and Share
Reverse osmosis is expressed by a French scientist in 1784. At that time he experimented with recording spontaneous water diffuses through the membrane into alcohol. After 200 out passed, this process known as reverse osmosis process. Reverse osmosis is able to make water that is unfit for consumption to be worthy of consumption and free of germs and bacteria.

The technology of reverse osmosis produces pure water. Usually places that need, such as:

1. Drinking water
2. Humadifikasi
3. Making ice
4. Rinse water
5. App biomedical
6. Application lab
7. Photography
And many others.

The workings of the system of reverse osmosis:

Semipermeable membrane is selective to the objects through it. The membrane is basically very easy because the water bypassed by a small molecular size. Although small molecules, the membrane is to prevent contaminants want through it. For the experiment, the water is filled on both sides of the membrane, one side has a different water concentrations of dissolved mineral. This is due to water has properties that move from low to high concentrations. So cause osmotic pressure opposite to the process of diffusion and form a balance.


Reverse Osmosis Process

The process of reverse osmosis water moving from the high concentrations of contaminants to low. So as to create a reverse process as opposed to the process of osmosis using high pressure water on the raw water. By using semipermeable membrane, so he let the water be passed through it, but still filter out contaminants that want to get into the water.

Although reverse osmosis able losing contaminants that exist, but periodically reverse osmosis should be cleaned so as not forming crust on the surface membrane. Reverse osmosis requires carbon to be first filter that can reduce the chlorine content of the accelerating destruction of a reverse osmosis membrane. So the filter is also necessary to filter sediment from water soluble raw materials so as not to clog the membrane.
