Polyaluminium Chloride Hydroxide Sulfate 8172
Polyalumınum Chlorıde Hydroxıde Sulfate - PACS
Polyaluminium Chloride Hydroxide Sulfate is a high basicity and SO4 containing product. SO4 helps to keep flocs more denser. SO4 content is < 3% so that residual sulfate formation doesn’t occur. It is a very effective coagulant for both municipal and industrial waste water.
An empirical formula, Aln(OH)mCl(3n−m), where 0 < m< 3n can be written to describe overall PAC composition. The degree of neutralization of hydrated Al(III), or basicity, is expressed as the mole ratio of OH/Al(m/n). This ratio is often called the ligand or hydroxyl number r: aluminum chloride has r = 0; aluminum hydroxide, r = 3; and PAC products have r values ranging from about 0.5 to 2.5. PAC solution products are always acidic. The pH ranges from < 1 to ca 4.0. The total aluminum concentration, conventionally expressed as Al2O3 or alumina content, is important to product composition and activity. Total Al content of PAC products as Al2O3 ranges from about 6 to 24% by weight in aqueous solutions.
PAC products can also contain other inorganic salts and these salts can affect PAC properties. Product Specifications
