Product Description
Poly aluminum chloride (PAC) is a polymeric inorganic compound. Chemically, it contains multiple aluminum-chlorine-hydroxide species. In water, it dissociates and forms positively charged complexes. These can neutralize the negative charges of suspended particles, causing them to aggregate. This property makes PAC effective in water treatment for impurity removal.

Application
1. Water treatment:
It is a highly effective coagulant in both drinking water and wastewater treatment. In raw water treatment, it neutralizes the charge of suspended particles such as clay and silt, causing them to aggregate into larger flocs. This makes it easier to remove these particles through sedimentation and filtration, resulting in clear and clean water. In wastewater treatment, it helps in removing various pollutants, including organic matter and some heavy metals, by facilitating the formation of settleable solids.
2. Paper industry:
Poly aluminum chloride is used to improve the retention of fillers and sizing agents in the papermaking process. It enhances the bonding between fibers and additives, which improves the strength and quality of the paper. Additionally, it can control the pH of the papermaking system, ensuring stable production and better paper properties.
3. Textile industry:
In textile dyeing and finishing, it is used as a mordant. It helps dyes to adhere better to the fabric fibers, resulting in more vivid and color-fast dyed textiles. It also plays a role in the pretreatment of textiles to remove impurities and prepare the fabric for better dye absorption.
