A pH or 7.0 is neutral and pH below 7.0 is, acidic, and pH above 7.0 is basic or alkaline. Modifying the ionic charge of wastewater changes the solubility of certain solids and also allows for physical solids to attract to each other. Selecting chemicals to adjust wastewater pH requires considering the chemical makeup of the wastewater.
