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.

Can flocculants be used in wastewater treatment?

The potential application of conventional flocculants, bio-flocculants and grafted flocculants in wastewater treatment has been verified and well investigated.

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.

Why are polymeric flocculants used in industrial effluent treatment?

Polymeric flocculants, synthetic as well as natural have become very popular in industrial effluent treatment due to their natural inertness to pH changes, high efficiency with low dosage, and easy handling (Singh et al., 2000).

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.

How effective is coagulant & flocculant?

Results showed that the most effective impact of coagulant and flocculant was the treated wastewater in Jar 5 using only 16 mg/L of PAC and 0.04 mg/L of PAM were used as coagulant and flocculant, respectively, resulting the value of the turbidity, pH, COD, BOD, and TSS was 2.00 NTU, pH 6.22, 2.00 mg/L, 5.22 mg/L, and 2.00 mg/L, respectively.
