Abstract

THE INVENTION IS AN ULTRAFILTRATION SYSTEM AND PROCESS FOR CONCENTRATING LATICES WITH ULTRASONIC FLUX ENHANCING AND MEMBRANE CLEANING CAPABILITIES. THE ULTRAFILTRATION SYSTEM FOR THE CONCENTRATION OF LATICES MAINLY COMPRISES A FIRST TANK (1), A SECOND TANK (2), A PUMP (3), AND AT LEAST ONE VERTICALLY DISPOSED ULTRAFILTRATION MEMBRANE MODULE (4). EACH MODULE IS PROVIDED WITH A PLURALITY OF VERTICALLY DISPOSED TUBULAR MEMBRANES (13) FOR FILTERING THE LATEX FEEDSTOCK AND WITH A PLURALITY OF ULTRASONIC TRANSDUCERS (9) TO GENERATE ULTRASONIC WAVES FOR ENHANCEMENT OF MEMBRANE PERMEATION FLUX. THE PROCESS OF ULTRAFILTRATION IS CARRIED OUT BY UTILIZING THE SYSTEM WHERE LATEX FEEDSTOCK IS PUMPED THROUGH THE MEMBRANE MODULE FOR ULTRAFILTRATION, WHERE LOWER MOLECULAR PORTIONS OF THE FEEDSTOCK PASS THROUGH THE TUBULAR MEMBRANE AS PERMEATE AND HIGHER MOLECULAR PORTIONS OF THE FEEDSTOCK ARE RETAINED AS RETENTATE (LATEX CONCENTRATE). THE PROCESS IS REPEATED UNTIL THE DESIRED LATEX CONCENTRATION IS ACHIEVED.
