Can Polyaluminium Chloride Be Used In Conjunction With Other Chemicals?

　　Polyaluminium chloride has now become a preferred choice for many in water treatment. However, many remain uncertain about its efficacy, unsure whether it performs better when used alone or in combination with other chemicals. Today, we shall explore how to correctly utilise polymerised aluminium chloride products to achieve optimal results.

　　Can polyaluminium chloride be used alongside other water purification agents? Certainly, polyaluminium chloride products are frequently employed in conjunction with other water treatment chemicals throughout the purification process. Poly Aluminium Chloride functions as a multifaceted water treatment agent, combining adsorption, coagulation, and bridging properties. Its primary active component is aluminium oxide, resulting in a slightly acidic solution upon dissolution. Optimal purification occurs within wastewater pH ranges of 6 to 9. Consequently, it may be employed either as a standalone treatment or in combination with other agents.
 

　　When combining with other agents, careful attention must be paid to the pH levels of the polyaluminium chloride. Mixing acidic polyaluminium chloride products with alkaline water treatment agents not only fails to yield favourable results but may produce adverse effects. Divergent pH levels can generate undesirable gases or precipitates, compromising purification objectives and complicating subsequent remediation processes. Consequently, when combining polyaluminium chloride with other agents, it is imperative to ensure compatibility in pH characteristics. To fully leverage the synergistic effects and advantages of polyaluminium chloride when used alongside other agents, preliminary testing is essential prior to application. Typically, polyaluminium chloride is added during water treatment. Once it has fully reacted with the water, filtration and sedimentation occur via filtration equipment. At this stage, other water purification chemicals may be introduced for clarification. This approach ensures each chemical functions optimally after co-addition and is generally applicable in most scenarios.

　　In summary, polyaluminium chloride products can be co-administered with other chemicals during water purification. However, attention must be paid to pH fluctuations and the sequence of addition when using two or more chemicals. This approach ensures optimal efficacy.
