The research investigated wastewater discharges from wet coffee processing plant (WCPP) combined with tap water (TW) treated by using Cyperus-ustulatus plant (P1), Typha-latifolia plant (P2) wetland. The WCPP wastewater was conducted by different combination (100%WW + 0% TW; 75% WW + 25% TW; 50% WW + 50% TW; 75%WW + 25% TW and 0% WW + 100% TW) after being irrigated for 21 days in the constructed wetland with P1, P2and control (without a plant). The highest value of total solids, chemical oxygen demand and biochemical oxygen demand increases were 76%, 95% and, 96%, respectively, removed wastewater treated by T3 (50% WW + 50% TW) with P2 wetland after 21 days irrigated. As a result, the combination of coffee wastewater with constructed wetland treatment methods was a low-cost, affordable, technically viable and eco-friendly treatment option for the wet coffee processing plant wastewater.
