What is the pH of sewage water? - Quora

Materials with a pH higher than this are considered alkaline, or basic. Materials with a, pH lower than 7, are considered acidic. Based on the source of the waste materials or sewage, the waste stream may be either alkaline or basic. It is the goal of sewage and wastewater treatment to treat the stream and return

On ,the pH, scale, a ,pH, of less than 7.0 is ,acidic,. A ,pH, of 7.0 is neutral, and a ,pH, greater than 7.0 is basic (alkaline). In addition to the concentration of [H+] ions, bases can be measured by the presence of ions called a hydroxide ion (abbreviated as OH-). For bases, ,the pH value, increases as the amount of hydroxide ions in the solution increases.
