Reverse Osmosis Reverse Osmosis is a membrane separation process in which feed water flows along the membrane surface under pressure. Purified water permeates the membrane and is collected, while the concentrated water, containing dissolved and undissolved material that does not flow through the membrane, is discharged to the drain. Reverse Osmosis systems remove salts, micro-organisms and high molecular weight organics. System capacity depends on three major factors. The feed water temperature Total Dissolved Solids in feed water ( TDS ) Operating pressure and the over all recovery of the system. Compared with other conventional water treatment processes, Reverse Osmosis has proven to be the most efficient means of removing salts, chemical contaminants and heavy metals, such as lead, from drinking water. |
