Method for treating water by ion exchange
Abstract
Abstract A METHOD IS PROVIDED FOR THE TREATMENT OF WATER BY ION EXCHANGE WHILE ELIMINATING LEAKAGE. IN CARRYING OUT THE METHOD, WATER IS FIRST PASSED THROUGH A SERVICE LAYER OF ANION AND CATION EXHANGE RESINS IN A SERVICE ZONE IN THE CONVENTIONAL MANNER. SUBSEQUENTLY, THE WATER IS PASSED THROUGH A LEAKAGE BARRIER LAYER OF CATION EXCHANGE RESIN IN THE SERVICE ZONE. PERIODICALLY, THE RESINS IN THE SERVICE ZONE ARE SEPARATED IN A SEPARATION ZONE. THE ANION EXCHANGE RESIN IS THEN REGENERATED IN AN ANION RESIN REGENERATION ZONE, AND THE CATION EXHANGE RESIN IS REGENERATED IN A CATION RESIN REGENERATION ZONE, WHICH PREFERABLY ALSO SERVES AS THE SEPARATION ZONE. A PORTION F THE CATION EXCHANGE RESIN IS THEN TRANSFERRED TO THE SERVICE ZONE TO ESTABLISH A LEAKAGE BARRIER LAYER. THE REMAINDER OF THE CATION EXCHANGE RESIN IS MIXED WITH THE ANION EXCHANGE RESIN, AND THE MIXED RESINS ARE TRANSFERRED TO THE SERVICE ZONE TO ESTABLISH A SERVICE LAYER OF ANION AND CATION EXCHANGE RESINS.
