PMID: 15272728. Abstract. Al13 or Alb is usually regarded as the most efficient species of polyaluminum chloride (PAC), the performance flocculant for water treatment. This paper was intended to report a new method to synthesize PAC with high content Alb, by using the membrane reactor.

Dec 15, 2003 · Polyaluminum chloride (PAC) with a high content of Al b, the most efficient species of PAC, was synthesized with a membrane reactor. In this reactor, NaOH solution permeated slowly through the micropores of an ultrafiltration membrane into AlCl 3 solution to reduce the NaOH drop size to nano-scale.

Feb 1, 2004 · In this study, a new composite flocculant prepared by polyaluminum chloride (PAC) and sodium alginate (SA) was used to treat dye and humic acid water in the coagulation–ultrafiltration process.

Polyaluminum Chloride-wastewater treatment chemical

Electrospray mass spectrometry has been reported as a novel technique for Al species identification, but to date, the working mechanism is not clear and no unanimous method exists for spectrum analysis of traditional Al salt flocculants, let alone for analysis of polyaluminum chloride (PAC) flocculants. Therefore, this paper introduces a novel theoretical calculation method to identify Al
