PH Adjustment: Sulphuric Acid is commonly used for pH adjustment in water treatment processes. It can be added to water to lower the pH and create optimal conditions for subsequent treatment steps such as coagulation, flocculation, and disinfection. Proper pH control is essential for effective water treatment.

Scale and Corrosion Control: In water systems, Sulphuric Acid is used to remove mineral scale deposits and control corrosion in pipes, boilers, and heat exchangers. It dissolves calcium carbonate (limescale) and other mineral deposits, preventing scaling that can impair water flow and heat transfer efficiency.

Metal Precipitation: Sulphuric Acid can be employed to precipitate metals in water treatment, particularly heavy metals such as lead, copper, and zinc. It reacts with metal ions to form insoluble sulphates, which can then be removed through sedimentation or filtration processes.

Phosphorus Removal: In wastewater treatment, Sulphuric Acid is used for phosphorus removal. It reacts with phosphates to form insoluble precipitates, aiding in the removal of phosphorus from wastewater effluent.

Neutralization of Alkaline Wastes: Sulphuric Acid is utilized for neutralizing alkaline wastes in water treatment plants. It helps neutralize excess alkalinity, stabilize pH levels, and facilitate the treatment of alkaline wastewater streams.
