초록

An economical and commercially practical reverse-osmosis water purifier system which has no back pressure acting against the semipermeable membrane, so that the filtering rate is maximized. Furthermore, the supply of tap water to the system is shut off automatically as soon as the pure water storage tank is full, use of water thus being greatly reduced. These, and other major advantages, are achieved despite the fact that there is only a single tube extending to the faucet, automatic ice-maker, refrigerated drinking fountain or other point of use. The sy...
