| reverse osmosis |
A filtration process that removes dissolved salts and metallic ions from water by forcing it through a semipermeable membrane. This process is also highly effective in removing microbes from water.

| reverse osmosis |
A process used to purify concentrated solutions (often water with high levels of dissolved salts) in which pressure is applied to the more concentrated (or contaminated) solution on one side of a semipermeable membrane. The result is the movement of solvent, but not solutes, from the more concentrated side to the more dilute side, thus separating clean solvent from the concentrated solution. ...

| reverse osmosis |
a process where water is cleaned by forcing water through an ultra-fine semi-permeable membrane which allows only the water to pass though and retains the contaminants; these filters are sometimes used in tertiary treatment and to pretreat water in chemical laboratories.

| reverse osmosis |
Reverse osmosis is a process that separates impurities from water by forcing it through filters under great pressure into a spirally wound tube called a reverse osmosis element. The membrane allows water to pass through the filter while rejecting suspended and dissolved impurities and most color and odor-causing compounds. If the filters do not absorb the contaminants, then they have to pass through three post-treatment cylinders

| reverse osmosis |
A treatment process used in water systems by adding pressure to force water through a semi-permeable membrane. Reverse osmosis removes most drinking water contaminants. Also used in wa- stewater treatment. Large-scale reverse osmosis plants are being developed.
