Poly Aluminium Chloride Structure
The structure of Poly Aluminium Chloride is composed of aluminum cations (Al3+) surrounded by hydroxyl ions (OH-) and chloride ions (Cl-). The combination of these ions results in a highly charged polymer with a net positive charge. This unique structure allows PAC to effectively neutralize the negative charges present in suspended particles in water, leading to the formation of flocs and facilitating their easy removal during the coagulation process.
Chemical Properties of PAC
Poly Aluminium Chloride exhibits several essential chemical properties that contribute to its effectiveness as a coagulant. It is highly soluble in water and capable of generating a wide range of polymeric species based on its degree of polymerization. PAC solutions are acidic due to the presence of hydrolyzed aluminum species. The effectiveness of PAC can be influenced by various factors such as pH, temperature, and the concentration of contaminants in the water.
Production of PAC
The production of Poly Aluminium Chloride involves a series of chemical reactions. One common method is the reaction between aluminum hydroxide (Al(OH)3) and hydrochloric acid (HCl), which leads to the formation of a highly reactive intermediate, AlCl3. This intermediate reacts further with water, resulting in the formation of PAC with different degrees of polymerization. The process is carefully controlled to obtain the desired properties and effectiveness of the final product.
