Poly Aluminum Chloride produced at Sulaksh Chemicals is appreciated by the clients for high quality standards just beacause of we produce it using quality chemicals as raw material that. Polyaluminium chloride (PAC) products are aluminium-based coagulants. They are similar to alum, with several important differences: 1. Partially pre-neutralised (Higher basicity than alum). 2. Contain Cl instead of SO4. 3. Contain up to 3 times the aluminium content.
