What is poly-Aluminium chloride (PAC)?

Poly-Aluminium Chloride (PAC)is a kind of highly effective water purificiant, which is wildly used in the purification of table water, industry water, industry circulation water and wasted and polluted water from pharmacy industry, paper making industry and printing and dying industry, as well as life wasted water.

What is Longwater® polyaluminium chloride (PAC/PACL)?

CAS No.:1327-41-9 EINECS No.:215-477-2 Chemical Formula: [AL2 (OH)nCL6-n] Longwater® Polyaluminium Chloride (PAC/PACL) as a kind of high effective inorganic compound polymer coagulant or flocculant. Longwater® All the polyaluminium chloride is manufactured by National Standard and almost equal to ANSI/AWWA Standard, JIS Standard, NSF Standard.

Which raw materials are used to make liquid PAC?

It has the ability to coagulate suspended solid or dispersed colloid within water perform easily precipitated flock. The raw materials used for manufacturing liquid PAC consists of hydrated alumina (Al (OH) 3), hydrochloric acid (HCl), sulfuric acid (H 2 SO 4) and calcium carbonate (CaCO 3).

What is PAC in chemistry?

The PAC is a complex inorganic substance between hydroxyl and aluminum ions that gradually takes place chlorination with its general formula of Al x (OH) y Cl 3x-y. It has the ability to coagulate suspended solid or dispersed colloid within water perform easily precipitated flock.

What is the optimum reaction time for a liquid PAC?

The optimum experiment produced liquid PAC with the highest Al 2 O 3 composition of 11.96% and the lowest Cl − ion of 10.87% at 2 hours reaction time with a total acid concentration of 37.74%. Export citation and abstract BibTeX RIS
