Abstract

The research was carried out to investigate wastewater discharge's technical viability from wet coffee processing plant (WCPP) treatments with aeration and Typha- latifolia plant. The WCPP wastewater was conducted at various aeration days (5, 10, 15, 20 and 25 days) after being irrigated for 21 days in the constructed wetland with Typha-latifolia plant and without a plant. The highest value of total solids, chemical oxygen demand and biochemical oxygen demand increasing were 87.8%, 97.4% and, 98.1 %, respectively, in 25 days aerated with Typha-latifolia plant wetland. After 25 days of aeration with Typha- latifolia plant  treated polluted water value of BOD₅ (93.2%), COD (91.7%) and TS (84.1%). The Typha-latifolia with 25 days aerated WCPWW reduced 94.2% and 98.1% of NO₃-N and PO₄³, respectively. As a result, the aeration days were increased with the removal efficiency of pollutants discharged from wet coffee processing plant increased with a constructed wetland. It shows that aeration with constructed wetland treatment method was a low-cost, affordable, technically viable and eco-friendly treatment option for the wet coffee processing plant wastewater.
