Abstract

The purpose of this study was to evaluate the viability of treating wastewater through edible plant hydroponics. After the harvest in the hydroponic experiment (32 day study period), plant yield for edible biomass (corresponds to the harvested leaves) in wastewater and hydrosol (control) were 0.131 kg/m2 and 0.104 kg/m2, respectively. Potassium, TDS, and TN showed decreasing trends in hydrosol and wastewater during the experiment. Nitrification was observed in the wastewater unit with a significant increase (92.5%) in nitrate mass. Nitrite and ammonium mass in wastewater decreased with time, while hydrosol had negligible amounts of nitrite and ammonium during the study period. Calcium and magnesium masses decreased in the control and increased in wastewater. Wastewater showed a decrease in the mass of TOC (19.7%), while the hydrosol had negligible mass with respect to TOC.
