Two commercial coagulants such as alum Al2(SO4)3·18H2O and polyaluminium chloride (PAC) were also utilized in this study in order to compare the coagulation efficiency with the natural coagulants. The EDX analysis of the raw semiconductor wastewater showed that it contained silica dioxide (SiO2) with a concentration of 90%. It appeared that the natural coagulants employed in the study have similar coagulation characteristics with the commercial coagulants. However, the natural coagulants possess better metal adsorption capability than the commercial coagulants. A 3 level factorial experimental design was used in the Response Surface Methodology (RSM) analysis and indicated that starches are capable to remove TS from the semiconductor wastewater and the removal performance were almost similar to alum and higher than PAC.
