Title
Treatment of Domestic Wastewater Using Mg-Sericite Flocculant
최희정 Hee Jeong Choi
Abstract
The aim of this study was to investigate the nutrient removal using Mg-Sericite flocculant in the domestic wastewater. Mg-Sericite flocculant removed successfully 98-100% of the nutrient in the domestic wastewater at the following optimal parameters: turbidity, TSS and COD by Mg-Sericite dosage 10 mg/L, TP and PO4-P by Mg-Sericite dosage 20 mg/L and NO3-N and TN by 25 mg/L and 30 mg/L Mg-Sericite dosage, respectively. These results indicated that a biopolymer, Mg-Sericite, can be a promising flocculant due to its high efficiency and low dose requirements. In addition, Mg-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.
