DEVELOPMENT OF A CENTRIFUGAL REVERSE-OSMOSIS DESALINATION UNIT OF INTERMEDIATE SCALE

A centrifugal reverse-osmosis desalination unit (ROD) offers many advantages over a conventional ROD. A centrifugal unit is more energy efficient, operates with lower levels of noise and vibration, and is not subject to the seal degradation and corrosion problems typical of a conventional unit. A centrifugal ROD producing 2600 liters per day of fresh water from seawater at 12 deg. C is described. The patented design incorporates features that overcome problems that have previously restricted such units to very large- scale applications.
