PAC Powder Al₂O₃ 30%–31% — Coagulation for Textile Dyeing, Wastewater Treatment | Loc Thien

PAC (Polyaluminium Chloride) powder (solid Poly aluminum chloride, CAS 1327-41-9) with an Al₂O₃ content ranging from 30%–31% is the superior choice for Wastewater Treatment of high-color wastewater (>200 Pt-Co) in Textile Dyeing and heavy industries. Compared to liquid PAC 17%, PAC powder has a higher concentration, lower shipping costs, is easier to store, and exhibits stronger coagulation activity. Loc Thien Chemical — a supplier of PAC powder, providing complete Certificates of Origin, Quality, and Analysis, as well as Material Safety Data Sheets (MSDS), in compliance with QCVN 40:2025 (superseding QCVN 40:2011, effective Sept 1, 2025)/MONRE, with delivery to industrial parks within 24–48 hours. ☎ 0979 891 929.

What Is PAC Powder Al₂O₃ 30%–31%? How Is It Different from Liquid PAC (Polyaluminium Chloride)?

Solid PAC powder (CAS 1327-41-9) is a concentrated form of polyaluminium chloride—an inorganic aluminum compound specifically used for coagulation and decolorization of wastewater. With a content / purity of Al₂O₃ ≥ 30%, PAC powder has an active ingredient density approximately 1.8 times that of liquid PAC (Polyaluminium Chloride) 17%, making it suitable for Wastewater Treatment systems in the Textile Dyeing industry with high color intensity (≥200 Pt-Co) at industrial parks such as VSIP, Nhon Trach, and Amata.
