Water demineralizing methods and systems

Claim 1

THE METHOD OF DEMINERALIZING RAW WATER, COMPRISING CIRCULATING WATER CONTAINING DISSOLVED METAL SALTS IN A CLOSED SERIES LOOP CIRCUIT FROM A BUFFER TANK THROUGH A POROUS CATION EXCHANGE BED ARRANGED IN THE TREATMENT CHAMBER OF A FIRST ELECTROLYTIC CELL AND THEN THROUGH A POROUS ANION EXCHANGE BED ARRANGED IN THE TREATMENT CHAMBER OF A SECOND ELECTROLYTIC CELL AND THENCE BACK TO SAID BUFFER TANK, WHEREIN SAID TWO BEDS HAVE SUBSTANTIALLY EQUIVALENT TOTAL ION EXCHANGE CAPACITITES, WHEREBY THE CIRCULATED WATER IS DEMINERALIZED BY THE REMOVAL THEREFROM OF SUBSTANTIALLY EQUIVALENT CATIONS AND ANIONS ACCOMPANIED BY SUBSTANTIALLY EQUIVALENT DEGENERATIONS OF THE ION EXCHANGE CAPACITIES OF SAID TWO BEDS, REGENERATING AT SUBSTANTIALLY EQUIVALENT RATES THE ION EXCHANGE CAPACITIES OF SAID TWO BEDS BY THE RESPECTIVE APPLICATIONS THEREACROSS OF INDEPENDENT DIRECT VOLTAGES, WHEREBY SAID TWO BEDS ARE MAINTAINED AT SUBSTANTIALLY EQUIVALENT STATES OF ION EXCHANGE REGENERATION IN ORDER TO AVOID BOTH RELATIVELY LOW PH WATER AND RELATIVELY HIGH PH WATER IN SAID BUFFER TANK, INTRODUCING RAW WATER INTO SAID LOOP CIRCUIT ON THE INLET SIDE OF SAID BUFFER TANK, WHEREIN SAID BUFFER TANK HAS A VOLUME SUFFICIENTLY LARGE TO EFFECT SUBSTANTIAL DILUTION OF THE RAW WATER INTRODUCED THEREINTO WITH THE PREVIOUSLY DEMINERALIZED WATER THEREIN, AND WITHDRAWING DEMINERALIZED WATER FROM SAID LOOP CIRCUIT ON THE OUTLET SIDE OF SAID BUFFER TANK.

Claim 2

THE METHOD OF DEMINERALIZING RAW WATER, COMPRISING CIRCULATING WATER CONTAINING DISSOLVED METAL SALTS IN A CLOSED SERIES LOOP CIRCUIT FROM A BUFFER TANK THROUGH A POROUS CATION EXCHANGE BED ARRANGED IN THE TREATMENT CHAMBER OF A FIRST ELECTROLYTIC CELL AND THEN THROUGH A POROUS ANION EXCHANGE BED ARRANGED IN THE TREATMENT CHAMBER OF A SECOND ELECTROLYTIC CELL AND THENCE BACK TO SAID BUFFER TANK, WHEREIN SAID TWO BEDS HAVE SUBSTANTIALLY EQUIVALENT TOTAL ION EXCHANGE CAPACITITES, WHEREBY THE CIRCULATED WATER IS DEMINERALIZED BY THE REMOVAL THEREFROM OF SUBSTANTIALLY EQUIVALENT CATIONS AND ANIONS ACCOMPANIED BY SUBSTANTIALLY EQUIVALENT DEGENERATIONS OF THE ION EXCHANGE CAPACITIES OF SAID TWO BEDS, REGENERATING AT SUBSTANTIALLY EQUIVALENT RATES THE ION EXCHANGE CAPACITIES OF SAID TWO BEDS BY THE RESPECTIVE APPLICATIONS THEREACROSS OF INDEPENDENT DIRECT VOLTAGES, WHEREBY SAID TWO BEDS ARE MAINTAINED AT SUBSTANTIALLY EQUIVALENT STATES OF ION EXCHANGE REGENERATION IN ORDER TO AVOID BOTH RELATIVELY LOW PH WATER AND RELATIVELY HIGH PH WATER IN SAID BUFFER TANK, INTRODUCING RAW WATER INTO SAID LOOP CIRCUIT ON THE INLET SIDE OF SAID BUFFER TANK, WHEREIN SAID BUFFER TANK HAS A VOLUME SUFFICIENTLY LARGE TO EFFECT SUBSTANTIAL DILUTION OF THE RAW WATER INTRODUCED THEREINTO WITH THE PREVIOUSLY DEMINERALIZED WATER THEREIN, AND WITHDRAWING DEMINERALIZED WATER FROM SAID LOOP CIRCUIT ON THE OUTLET SIDE OF SAID BUFFER TANK.
