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 …

Acidity and Alkalinity - wastewater treatment
Acidity and Alkalinity - wastewater treatment

Acidity is a measure of a solution’s capacity to react with a strong base (usually sodium hydroxide, NaOH) to a predetermined pH value. This measurement is based on the total ,acidic, constituent of a solution (strong and weak acids, hydolyzing salts, etc.) It is possible to have highly ,acidic, water but have moderate pH values.

What is, Acidic Waste Water., Many common, wastewaters, are considered, acidic. Acidic, is defined as having a pH of less than 7. The pH scale measures how, acidic, or alkaline (basic) a substance is. The scale is logarithmic and each pH value below 7 is ten times more, acidic, than the next level.
