Abstract:
This 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 of treatments (i.e.
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 wastewate
