The aim of this study was to investigate the car wash wastewater using corncob. Corncob was removed successfully the organic and anorgnic matters in the car wash wastewater at the following optimal parameters: 10 g/L of corncob, 150 rpm of mixing rate and from 6 to 7 of pH. The removal efficiency of turbidity, TDS (Total Dissolved Solid), and ABS (AlkylBenzene Sulfonates) were very high, more than 96%. However COD (Chemical Oxygen Demand), TN (Total Nitrogen) and TP (Total Phosphorus) was found to be 63-65%, 83-87% and 83-84%, respectively, and was relatively low removal efficiency compared turbidity, TDS and ABS. In particular, COD and TP exceeded the wastewater discharge standard and it is considered that post-treatment is necessary for stable treatment of car wash wastewater. Despite the low COD removal, treating car wash wastewater using corncob is very attractive. Because corncob can be treated with abandoned agricultural by-products to treat wastewater, and environmentally friendly because they are not using chemicals. Especially, turbidity, TDS and ABS have high removal efficiency, so that it is possible to reduce the processing cost of wastewater treatment if they are used as pre-treatment.
