Can polyaluminum chloride be used in water treatment?

In this study, synthesis and speciation of polyaluminum chloride (PAC) for application in water treatment was investigated using a colorimetric speciation method. It was possible to produce stable preparations of PAC solutions in which a relatively stable cationic polymer predominated.

Can polyaluminum chloride coagulant be used to treat petroleum wastewater?

This work investigates the potential synthesis of cost-effective polyaluminum chloride (PACl) coagulant from waste household aluminum foil and utilization for treating petroleum wastewater (PWW), especially dissolved organic compounds (DOC, like octanol–water mixture) and nonsettleable suspended (NSS-kaolin) mineral particles.

Does polyaluminum chloride remove colloidal matter from dam water?

In the present work, a new composite coagulant of the inorganic–organic type, prepared by polyaluminum chloride (PAC) premixed with sodium alginate (SA), was tested to remove colloidal matters from dam water.

Are polyelectrolytes grafted into Pac and aluminum forms distribution effective?

However, the selection of polyelectrolytes grafted into PAC and aluminum forms distribution in the coagulant composite is under continuous evaluation and update. This study evaluated the effectiveness of new composite coagulants based on polyaluminum chloride (PAC) and sodium alginate (SA) to remove the colloidal matter from dam water.

Why is polyaluminum chloride used as a catalyst?

Polyaluminum chloride (PAC) was used as a catalyst for the first time to synthesize bis (indolyl) methane compounds. PAC catalyst has the advantages of high efficiency, green, mild and recyclable. Al O polynuclear cations in PAC may have a synergistic catalytic effect.

Which polyvalent ions enhance the performance of polyaluminum chloride in water treatment?

Polyvalent anions including sulfate and phosphate are known to enhance the performance of polyaluminum chloride in water treatment. The ions can be incorporated into the products of the present invention either before, during, or after the process of raising the basicity.
