Description
Calcium Hypochlorite for Water Treatment & Sanitization
Calcium Hypochlorite (Ca(ClO)₂), known as bleaching powder or chlorinated lime, is a powerful chlorine-releasing compound used for water treatment, pool sanitization, and industrial bleaching. With 65-70% available chlorine, this white to light gray crystalline powder offers robust disinfection and sanitization. Its stability and long shelf life make it ideal for municipal water treatment, swimming pool maintenance, food processing, and emergency water purification.
