What is the chemical formula of poly Aluminium chloride India?
The Poly Aluminium Chloride chemical formula can vary depending on its degree of polymerization, typically represented as [Al2 (OH)nCl6-n], where ‘n’ is the number of hydroxyl groups. This unique chemical formula of Poly Aluminium chloride India plays a crucial role in its coagulation properties and effectiveness in various applications.
What is the optimal pH range for poly Aluminium chloride?
Its optimal performance occurs at a neutral pH range of 6.5 to 7.6. Poly Aluminium Chloride achieves this by generating hydroxyl ions and polyvalent anionic polymers, which facilitate the coagulation and flocculation of suspended particles to improve water quality.
How do I find the correct dosage of poly Aluminium chloride?
To find the correct dosage of Poly Aluminium Chloride for your specific application, take the following corresponding information for your reference: National Standards: In most countries, the standard content of solid PAC is 28%, and for the liquid form, it’s 10%.
