What is Reverse Osmosis?

Answer 1

RO is molecular sieving. A porous tube is coated with acetate on the inside and water is forced through it under pressure. Almost all of the ions and particulated are filtered out and pass out the end of the tube.

Answer 2

In reverse osmosis, the idea is to use a membrane to act like an extremely fine filter to create drinkable water from salty (or otherwise contaminated) water. The salty water is put on one side of the membrane and pressure is applied to stop, and then reverse, the osmotic process. It generally takes a lot of pressure and is fairly slow, but it works.

Answer 3

Reverse osmosis is the process of forcing a solvent from a region of high solute concentration through a membrane to a region of low solute concentration by applying a pressure in excess of the osmotic pressure.

Answer 4

I'm not sure but i know osmosis is the diffusion of water which is when a high concentration of water travel to an area with a low concentrated of water. my guess is that reverse osmosis is the opposite of osmosis or when a low concentration of water travel to a high concentration of water.

Answer 5

Osmosis, in reverse!

Answer 6

Biologically or reversing the word?

Filtering water thru a semi pearmable membrane that usually wont allow alot of particules pass thru.
or
Sisomso.lol

Answer 7

Don't know but omosis in plumbing terms is something to do with air being absorbed into pipework, therefore causing oxidisation (rust to you and me) due to the mixture of water, metal (usually copper or cast iron) and air.Steps have been made to counter this with the introduction of plastic pipe with a barrier to prevent the air getting into the system... God actually sound a little bit clever there.
