Abstract:
was carried out to investigate wastewater discharge’s technical viability from wet cof fee processing plant (WCPP) treatments with aeration and Cyperus ustulatus plant, Typha latifolia
plant. The WCPP wastewater was conducted at various aeration days (5, 10, 15, 20 and 25 d) after
being irrigated for 21 d in the constructed wetland with Cyperus ustulatus and 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 d aerated with Typha
latifolia plant (P2) wetland. After 25 d of aeration with Cyperus ustulatus plant (P1) treated polluted
water value of biological oxygen demand (97.8%), chemical oxygen demand (96.9%) and total sol ids (88.5%). The Typha latifolia (P2) with 25 d 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.
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
