pH Correction of Cooling Water & Effluent Water: Comparison between Lime and Caustic Soda

摘要

Generally industrial cooling water tends to have a pH of more than 7.5 to 8 due to the presence of bi-carbonates or other alkaline compounds in it. As such pH correction is not required for Cooling Water. Effluent water can have a pH less than 7.0, thus pH correction is required here for further treatment.
