Industrial district WWTP effluent had the prospective to be recycled with its large quantity. This research finds the feasibility of industrial WWTP effluent recyclability with adsorption. Adsorption studies done with batch with contact time and adsorbent mass variation, and continous studies with HLR variation. Freundlich isotherm model is the best fit model with Kf 0,0057, n 0,61, and R2 0,97. Pseudo-second order is the best fit for adsorption kinetics, with Ks 0,02668, qe 2.34, and R2 0,91. Breakthrough curve and its parameters also studied. YoonNelson and Thomas model could describe the adsorption well with R2 value >0,92 for every variation. Water recycle from adsorption effluent is feasible with TSS, COD, amonia, and color concentration at breakthrough is 50, 7.96, 0,002, and 13 mg/L respectively, and met the quality standard for class II PP No. 22 tahun 2021. Scale-up design for industrial scale also calculated, with carbon required is 4.83 kg GAC/m3 .
