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. The
Typha-latifolia with 25 days aerated WCPWW reduced 94.2% and 98.1% of NO3-N and PO4
3
, 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 with Typha-latifolia. 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
