Abstract

A METHOD OF MONITORING A MICROBIOLOGICAL PROCESS IN A FLUID SUPPLY INVOLVING ISOLATION OF A FLUID SAMPLE FROM A FLUID SUPPLY, MEASURING THE pH OF THE FLUID SAMPLE AT SELECTED TIME INTERVALS, THEN ANALYZING CHANGES IN pH, IF ANY, TO DETERMINE A pH VARIATION RATE FOR THE SAMPLE. THE DISSOLVED OXYGEN IN THE SAMPLE IS ALSO MEASURED AT SELECTED TIME INTERVALS SUBSTANTIALLY SYNCHRONOUSLY WITH THE PH MEASUREMENTS, AND CHANGES IN DISSOLVED OXYGEN, IF ANY, ARE ANALYZED TO DETERMINE A BIOLOGICAL OXYGEN CONSUMPTION RATE FOR THE SAMPLE.
