        The malodor as the sense pollutions is rising to surface with a new environmental matter. Especially, malodor"s appeal is increasing steadily from a residential area of the industrial complex. The odor characteristic and odor active compounds of industries should be identified to solve this problem. The dye company was selected as a sample among the industries. Air samples of the dye company were sampled with polyester aluminum bag and it was analyzed by GC/FID/O and GC/MS. The feature of the complex odor was ironing, sour and burnt smell. The odor active compounds of individual odor which contribute these smell were mainly 2-ethyl-hexanal, octanal, 2-ethyl-1-hexanol and nonanal. This study will help odor problem of industries to solve effectively.

        The aim of this study was to investigate the nutrient removal using Mg-Sericite flocculant in the dyeing wastewater. Mg-Sericite flocculant was removed successfully > 98% of the Color, SS. COD and BOD in the dyeing wastewater at the following optimal Mg-Sericite dosage: 100 mg/L for Colour and SS, 300 mg/L for BOD and COD. The removal of TN and TP was obtained 92.00% with 50 mg/L and 87.80% with 100 mg/L Mg-Sericite dosage, respectively. These results was indicated that the amount of 0.79~1.31, 0.22~0.37, 0.5 and 0.16 mg/L Mg-Sericite was necessary for 1 mg/L removal BOD, COD, TN and TP, respectively. The biopolymer, Mg-Sericite, can be a promising flocculants 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. This flocculation method is helpful to lower the wastewater treatment cost.
