Sulfuric Acid pH Adjuster for Water Treatment
CAS Number: 7664-93-9
Sulfuric acid is the most widely used acidic pH adjustment chemical in water and wastewater treatment, RO system pretreatment, and cooling water systems. It lowers pH, reduces alkalinity, controls calcium carbonate scale in RO membranes, and neutralizes alkaline effluents. It is used in diluted form for safe handling and accurate dosing by metering pumps.
