نویسندگان

چکیده

One of the traditional arts in Indonesia is Jumputan fabric which produced by using tie and dye technic. The wastewater contains organic compounds can decrease oxygen content water. An economic applicable process to handle adsorption. research was conducted find out effect flowrate adsorption performance onto activated carbon a continuous fixed-bed column based on breakthrough curve parameter. made from betel nuts (Cyrtostachys lakka) with size particle 60 mesh. dimension 2 inches inside diameter cm height column. bed 10 cm. feed pumped top variation 10, 20 30 ml/min. absorbance analyzed UV-Vis spectrophotometer. models were Thomas, Yoon-Nelson, Adam-Bohart. result this removal efficiency decreased increase flowrate, 61.4%; 56.9%; 47.6% for 20, ml/min respectively. Feed showed negative saturation time, higher faster it reaches point adsorbent. breakpoints 180, 260, 420 minutes at 30, flowrate. model data indicated that Thomas Yoon-Nelson are fitted well experimental results. show largest regression smallest error value each 0.99 0.0035
