초록

An over-the-counter, free-standing, water purification system including a pressure vessel that encloses a reverse-osmosis separator. Tap water at a pressure of between approximately 20 and 100 psig is introduced into the pressure vessel and a portion of the water is forced through the reverse-osmosis separator, while the remaining water is discharged from the pressure vessel along with the pollutants that are too large to penetrate the membrane of the reverse-osmosis separator. The product water passes through the reverse-osmosis separator at a rate of b...
