Method of disinfecting and automati-

Claim 1

THE METHOD OF DISINFECTING WATER IN A SWIMMING POOL AND AUTOMATICALLY MAINTAINING IT AT A PH OF BETWEEN 7.4 AND 7.8 WHEN SAID SWIMMING POOL INCLUDES A POWERDRIVEN PUMP, A FILTER, A SUCTION LINE CONNECTED TO SAID PUMP AND POOL, A FIRST DISCHARGE LINE CONNECTED TO SAID PUMP AND FILTER, AND A SECOND DISCHARGE LINE CONNECTING SAID FILTER TO SAID POOL, COMPRISING THE STEPS OF: (A) ENERGIZING SAID PUMP TO DRAW WATER FROM SAID SWIMMING POOL THROUGH SAID SUCTION LINE AND DISCHARGE THE SAME BACK INTO SAID SWIMMING POOL THROUGH SAID FIRST DISCHARGE LINE, FILTER AND SECOND DISCHARGE LINE; (B) EXPOSING SAID WATER AS IT DISCHARGES THROUGH SAID FIRST DISCHARGE LINE TO A MIXTURE OF CALCIUM HYPOCHLORITE AND A CARBONATE SALT OF SODIUM TO PERMIT SAID MIXTURE TO THEREAFTER REACT IN SAID FIRST AND SECOND DISCHARGE LINES, SAID FILTER, AND IN SAID SWIMMING POOL TO FORM FINELY PRECIPITATED CALCIUM CARBONATE, SODIUM HYPOCHLORITE, CARBON DIOXIDE AND WATER, WHICH SODIUM HYPOCHLORITE IN SAID EXPOSED WATER IS IN THE FORM OF HYPOCHLOROUS ACID AND SODIUM HYDROXIDE, WITH SAID SODIUM HYDROXIDE IN SAID EXPOSED WATER COMBINING WITH SAID CARBON DIOXIDE THEREIN TO FORM SOLUBLE SODIUM BICARBONATE TO LOWER THE PH OF SAID EXPOSED WATER, AND WITH SAID HYPOCHLOROUS ACID IN SAID EXPOSED WATER DECOMPOSING DUE TO ITS DISINFECTING, OXIDIZING OR BLEACHING ACTION INTO OXYGEN AND HYDROCHLORIC ACID, WITH SAID HYDROCHLORIC ACID IN SAID EXPOSED WATER NEUTRALIZING ANY SODIUM HYDROXIDE REMAINING THEREIN TO FORM SODIUM CHLORIDE AND WATER; (C) RECIRCULATING SAID EXPOSED WATER THROUGH SAID SUCTION LINE, PUMP, FIRST DISCHARGE LINE, FILTER AND SECOND DISCHARGE LINE TO DEPOSIT SAID CALCIUM CARBONATE PRECIPITATED IN SAID EXPOSED WATER AS A LAYER ON SAID FILTER; AND (D) CONTINUING TO RECIRCULATE SAID EXPOSED WATER TO PERMIT HYDROCHLORIC ACID THEREIN TO REACT WITH SAID CALCIUM CARBONATE ON SAID FILTER TO FORM CALCIUM CHLORIDE, CARBON DIOXIDE AND WATER TO RAISE THE PH OF SAID EXPOSED WATER, WITH SAID CARBON DIOXIDE REACTING WITH SAID CALCIUM CARBONATE AND WATER TO PROVIDE RESIDUAL CALCIUM BICARBONATE IN SAID EXPOSED WATER THAT BUFFERS THE SAME AGAINST ANY CORROSIVE TENDENCY IT MAY HAVE ON SAID SWIMMING POOL, PUMP, SUCTION LINE, FILTER, AND FIRST AND SECOND DISCHARGE LINES.

Claim 2

THE METHOD OF DISINFECTING WATER IN A SWIMMING POOL AND AUTOMATICALLY MAINTAINING IT AT A PH OF BETWEEN 7.4 AND 7.8 WHEN SAID SWIMMING POOL INCLUDES A POWERDRIVEN PUMP, A FILTER, A SUCTION LINE CONNECTED TO SAID PUMP AND POOL, A FIRST DISCHARGE LINE CONNECTED TO SAID PUMP AND FILTER, AND A SECOND DISCHARGE LINE CONNECTING SAID FILTER TO SAID POOL, COMPRISING THE STEPS OF: (A) ENERGIZING SAID PUMP TO DRAW WATER FROM SAID SWIMMING POOL THROUGH SAID SUCTION LINE AND DISCHARGE THE SAME BACK INTO SAID SWIMMING POOL THROUGH SAID FIRST DISCHARGE LINE, FILTER AND SECOND DISCHARGE LINE; (B) EXPOSING SAID WATER AS IT DISCHARGES THROUGH SAID FIRST DISCHARGE LINE TO A MIXTURE OF CALCIUM HYPOCHLORITE AND A CARBONATE SALT OF SODIUM TO PERMIT SAID MIXTURE TO THEREAFTER REACT IN SAID FIRST AND SECOND DISCHARGE LINES, SAID FILTER, AND IN SAID SWIMMING POOL TO FORM FINELY PRECIPITATED CALCIUM CARBONATE, SODIUM HYPOCHLORITE, CARBON DIOXIDE AND WATER, WHICH SODIUM HYPOCHLORITE IN SAID EXPOSED WATER IS IN THE FORM OF HYPOCHLOROUS ACID AND SODIUM HYDROXIDE, WITH SAID SODIUM HYDROXIDE IN SAID EXPOSED WATER COMBINING WITH SAID CARBON DIOXIDE THEREIN TO FORM SOLUBLE SODIUM BICARBONATE TO LOWER THE PH OF SAID EXPOSED WATER, AND WITH SAID HYPOCHLOROUS ACID IN SAID EXPOSED WATER DECOMPOSING DUE TO ITS DISINFECTING, OXIDIZING OR BLEACHING ACTION INTO OXYGEN AND HYDROCHLORIC ACID, WITH SAID HYDROCHLORIC ACID IN SAID EXPOSED WATER NEUTRALIZING ANY SODIUM HYDROXIDE REMAINING THEREIN TO FORM SODIUM CHLORIDE AND WATER; (C) RECIRCULATING SAID EXPOSED WATER THROUGH SAID SUCTION LINE, PUMP, FIRST DISCHARGE LINE, FILTER AND SECOND DISCHARGE LINE TO DEPOSIT SAID CALCIUM CARBONATE PRECIPITATED IN SAID EXPOSED WATER AS A LAYER ON SAID FILTER; AND (D) CONTINUING TO RECIRCULATE SAID EXPOSED WATER TO PERMIT HYDROCHLORIC ACID THEREIN TO REACT WITH SAID CALCIUM CARBONATE ON SAID FILTER TO FORM CALCIUM CHLORIDE, CARBON DIOXIDE AND WATER TO RAISE THE PH OF SAID EXPOSED WATER, WITH SAID CARBON DIOXIDE REACTING WITH SAID CALCIUM CARBONATE AND WATER TO PROVIDE RESIDUAL CALCIUM BICARBONATE IN SAID EXPOSED WATER THAT BUFFERS THE SAME AGAINST ANY CORROSIVE TENDENCY IT MAY HAVE ON SAID SWIMMING POOL, PUMP, SUCTION LINE, FILTER, AND FIRST AND SECOND DISCHARGE LINES.
