Characteristics of Wastewater | Wastewater Management

A high concentration of either an acid (pH ≪ 7) or alkali (pH ≫ 7) in wastewater is indicative of industrial wastes. The determination of pH value of sewage is important since certain treatment methods depend on proper pH value of the wastewater for their efficient workings. Sometimes, lime is added for creating alkaline condition.
