RO-620 ─Reverse Osmosis System

'Osmosis' is the process by which water and nutrients are
supplied to living cells. The natural flow of water is from a
diluted to concentrated solution, which passes across the
cells' walls. Cell walls are natural, selective, semi-permeable
membranes that allow some materials to pass through, but
not others. In a reverse osmosis procedure, pressure is used
to turn back - reverse - the natural flow of water through a
synthetic membrane so that pure water molecules pass
through but impurities are flushed away.
