Abstract

A BOILER FEED WATER TREATMENT SYSTEM (1, 100, 200) THAT INCLUDES TWO OR MORE WATER SOFTENERS (20, 21), A TOTALIZER (4) FOR MEASURING A QUANTITY OF WATER TREATED BY EACH SOFTENER (20, 21) BETWEEN REGENERATION CYCLES, A HARDNESS ANALYZER (5) FOR MEASURING THE HARDNESS OF WATER TREATED BY THE SOFTENERS (20, 21), A CHEMICAL DOSER (7,107) FOR INTRODUCING A SCALE INHIBITOR INTO THE FEED WATER AND A CONTROLLER (9, 209A, 209B) FOR CONTROLLING THE OPERATION OF THE SYSTEM (1, 100, 200). THE CONTROLLER (9, 209A, 209B) CONTROLS THE CHEMICAL DOSER (7, 107) TO INTRODUCE INTO OR INCREASE THE CONCENTRATION OF A SCALE INHIBITOR INTRODUCED INTO THE FEED WATER IF A HARDNESS MEASURED BY THE HARDNESS ANALYZER (5) EXCEEDS A FIRST THRESHOLD AND A WATER QUANTITY MEASURED BY THE TOTALIZER (4) IS BELOW A SECOND THRESHOLD. THE CONTROLLER (9, 209A, 209B) ALSO SHIFTS BETWEEN THE SOFTENERS (20, 21) IF THE MEASURED HARDNESS EXCEEDS THE FIRST THRESHOLD AND THE MEASURED WATER QUANTITY EXCEEDS THE SECOND THRESHOLD OR IF THE MEASURED HARDNESS IS LESS THAN THE FIRST THRESHOLD AND THE MEASURED WATER QUANTITY EXCEEDS A THIRD THRESHOLD. THE SECOND AND THIRD THRESHOLDS CORRESPOND RESPECTIVELY TO A FRACTION AND A MULTIPLE OF THE ESTIMATED TREATMENT CAPACITY OF EACH OF THE SOFTENERS (20, 21). (FIG. 1)
