Abstract

POTABLE WATER IS MANUFACTURED FROM SEA WATER BY PASSING IT SERIALLY THROUGH TWO REVERSE OSMOSIS UNITS. THE PRODUCT OF THE FIRST UNIT IS OF SUFFICIENT PURITY AND UNDER SUFFICIENT PRESSURE AS THE RESULT OF THE FIRST UNIT PRESSURIZATION TO ENABLE THE SECOND UNIT TO BE OPERATED WITHOUT REPRESSURIZATION. POTABLE WATER IS MANUFACTURED FROM SEA WATER BY PASSING IT SERIALLY THROUGH TWO REVERSE OSMOSIS UNITS. THE PRODUCTS OF THE FIRST UNIT IS OF SUFFICIENT PURITY AND UNDER SUFFICIENT PRESSURE AS THE RESULT OF THE FIRST UNIT PRESSURIZATION TO ENABLE THE SECOND UNIT TO BE OPERATED WITHOUT REPRESSURIZATION.
