Aluminium Sulfate Al₂(SO₄)₃ — Coagulant

Description

1. Product Overview

Aluminium Sulfate (Al₂(SO₄)₃) is a widely used inorganic coagulant utilized in water and wastewater treatment processes to remove suspended solids, turbidity, and impurities. It functions by destabilizing colloidal particles and facilitating the formation of flocs that can be easily separated through sedimentation or filtration.

Recognized for its high efficiency and cost-effectiveness, Aluminium Sulfate plays a critical role in municipal water purification, industrial effluent treatment, and paper manufacturing. Its proven performance, broad regulatory acceptance, and scalable dosing capabilities make it a strategically important chemical for water infrastructure and environmental management worldwide.
