Polyaluminium chloride (PAC) was used as coagulant with cationic and anionic polymers as coagulant aids. The results were subsequently compared with the study in which PAC was used alone for the treatment. Jar test apparatus was used to conduct research work.

How is a polyaluminium ferric chloride flocculant prepared?

A highly efficient polyaluminium ferric chloride (PAFC) flocculant was prepared by adjusting the pH of a leaching solution, the molar ratio of Al to Fe, and the polymerisation temperature. The effects of synthesis and flocculation conditions on the flocculation performance of aged landfill leachate were investigated.

Can red mud be used to synthesise polyaluminium ferric chloride (PAFC) flocculant?

Red mud was used to synthesise polyaluminium ferric chloride (PAFC) flocculant. The COD and TOC of PAFC to landfill leachate were 72.2% and 82.6%, respectively. PAFC have advantages over commercial PAFC in settlement velocity and TOC removal efficiency. In this study, red mud was used as a raw material to extract Al and Fe using hydrochloric acid.

What is the optimum polymerisation temperature for PAFC flocculants?

The results confirmed that PAFC flocculant prepared at a polymerisation pH of 2.5, Al/Fe molar ratio of 8, and polymerisation temperature of 70 °C had the optimum effect. The effect of PAFC and commercial polyaluminium ferric chloride flocculants used under different flocculation conditions were compared.

Can a PAFC flocculant be used for wastewater treatment?

Based on these results, it can be concluded that a PAFC flocculant has significant potential for use in the pre-treatment and purification of wastewater. Table 1. Comparison of the effects of different flocculants for wastewater treatment.

Does polyaluminum chloride coagulate with hydrolyzed coagulants?

Coagulation with hydrolyzing coagulants has been studied thoroughly, but the coagulation behavior of pre-hydrolyzed coagulants such as polyaluminum chloride (PACl), especially the coagulation mechanisms at various coagulant dosages and pH values of raw water, has not been systemically investigated and not been well understood , .

Does PAFC flocculation affect the performance of cpafc on landfill leachate?

The supernatant obtained via PAFC flocculation treatment was lower than the concentration of Al (0.2 mg/L) and Fe (0.3 mg/L) set out in the Chinese drinking water sanitation standard GB5749-2006. The flocculation indexes measured confirmed that the flocculation performance of PAFC on landfill leachate could reach the effect of CPAFC.
