Sulfuric Acid pH Control Agent (Water Treatment)
CAS Number: 7664-93-9
Technical grade concentrated sulfuric acid (98%) used for pH depression in water treatment applications including reverse osmosis pre-treatment, cooling water pH control, and wastewater neutralization. It converts bicarbonate alkalinity to CO2 to control scaling potential in high-hardness feed waters and is used to maintain optimal coagulation pH in drinking water treatment.
