  • Getting back to basics: What is pH?

    Getting back to basics: What is pH? The most used measure in wastewater treatment, and for good reasons The “potential of hydrogen” or “pH” is the measure of free hydrogen activity in water and thereby indicative of the measure of its free acidity or free alkalinity. Gauged on a numeric scale of 0-14, solutions with a pH of less than 7.0 are acids. ...
