pH is a scale of measurement expressing the acidity or alkalinity of the wastewater. In the pH scale, a value below 7 shows that a wastewater is acidic, a value of 7 is neutral, and values higher than 7 are alkaline. The pH values are logarithmic, meaning a pH of 6 is 10 times more acidic than a pH of 7.
