The aim of this study was to investigate the nutrient removal using methyl esterified sericite (ME-Sericite) flocculant in the domestic wastewater. ME-Sericite flocculant was removed successfully ＞ 98% of the Clolur, SS. COD and BOD in the wastewater at the following optimal ME-Sericite dosage: 100 mg/L for Colour and SS, 200 mg/L for BOD and COD. The removal of TN and TP was obtained 95.00% with 50 mg/L and 94.80% with 100 mg/L ME-Sericite dosage, respectively. These results was indicated that the amount of 0.79-1.01, 0.22-0.31, 0.32 and 0.15 mg/L ME-Sericite was necessary for 1 mg/L removal BOD, COD, TN and TP, respectively. The biopolymer, ME-Sericite, can be a promising flocculants due to its high efficiency and low dose requirements. In addition, ME-Sericite does not contaminate treated wastewater, which can be recycled to reduce not only the cost and the demand for water but also the extra operational costs for reusing wastewater. |
