1. Purification effect: Basic aluminum chloride can undergo chemical reactions with impurities and suspended matter in water to form a stable precipitate, making the water clear and transparent. Additionally, it can bind with organic substances in water, causing them to aggregate and settle, further improving water quality.
2. Coagulation aid effect: Basic aluminum chloride is an effective coagulant aid that enhances the sedimentation performance of suspended matter and pollutants in water, thereby achieving the goal of water purification. Its coagulation aid effect is primarily realized through its ionic form, which generates alkaline ions to attract non-charged suspended matter, adsorbing them in water to form numerous small crystals that eventually settle at the bottom.
3. Auxiliary water treatment agent: Basic aluminum chloride can serve as an auxiliary agent in water treatment to reduce pollutants in water, such as bacteria, organic matter, heavy metals, and other toxic substances, thereby achieving the goal of water purification.
