| Abstract | Sludge containing aluminium hydroxide generated in the C₅ resin processing, was currently disposed by landfill. In this research, this sludge was used as the raw material for synthesizing poly(aluminium chloride) or PAC. PACs with different OH/Al molar ratios (n= 0-3) and poly(aluminium silicate chloride) or PASiC. PASiC with different Si/Al molar ratios (n= 5-20) were prepared by acid hydrolysis method. The dried sludge contained Al₂O₃ 43.95 % (w/w) or aluminium content 23.26 % (w/w). The products were characterized by x-ray diffraction spectroscopy, fourier transform infrared spectroscopy, and aluminium species distribution using the ferron technique. The performance of synthesized coagulants was investigated by jar test with water sample from rayong river and was monitored with turbidity, pH and time of coagulation. The PAC with OH/Al molar ratios (2.5:1) exhibited to be the best of all PACs and gave similar results of comercial PAC and the PASiC with Si/Al molar ratios (1:20) gave high performance more than comercial PAC. |
