Abstract
Abstract AN EXPANDABLE STERILIZED BAG IN A STORAGE TANK IS SECURED TO INLET AND OUTLET CONNECTION SO THAT PURIFIED WATER ENTERING THE TANK IS CONFINED SOLELY WITHIN THE BAG. THE TOP OF THE TANK IS CLOSED SO THAT AIR TRAPPED THEREIN LIMITS THE LEVEL TO WHICH WATER IN THE BAG CAN RISE. CLOSURE OF THE TOP OF THE TANK IS EFFECTED BY AN INVERTED CUP HAVING ITS RIN FORCED AGAINST A SEAL AROUND AN OPENING IN THE TOP OF THE TANK, SUCH CUP SUPPORTING AN ULTRAVIOLET LAMP ABOVE A QUARTZ PLATE THAT EXTENDS ACROSS THE OPENING.
