An Experimental Study of Phytoremediation of Greywater Using Water Hyacinth (Eichhornia crassipes)
Subject area: Science,Engineering and Technology · Area of research: Agricultural Engineering
Abstract
This study investigates the potential of water hyacinth (Eichhornia crassipes) in the phytoremediation of greywater. Greywater samples were treated using water hyacinth in a controlled environment over a 5-day period. The physicochemical parameters considered were pH, electrical conductivity (EC), total dissolved solids TDS, and salinity. Three replicates of ten (10) liters of greywater in a plastic trough, each containing roughly 150 g of water hyacinth, were observed every day for five days. The electrical conductivity (EC), pH, total dissolved solids (TDS), and salinity treatment parameters were measured in the experiment. The treatment means were then computed. The results indicated that after three days of the study, the majority of the water parameters had decreased to their maximum. A 57% decrease in both EC and TDS and a 15% decrease in salinity were recorded. Also, a phytoremediation rates of +0.15 g/day for EC, +0.097g/day for TDS and +5.5 x 10 -5 g/day for salinity were observed. After three days, the water hyacinth began to exhibit symptoms of nutritional deficiency and later, re-introduction of absorbed pollutant. At 95 percent confidence level for EC and TDS, an Anova indicates that there was no significant difference between the control and water hyacinth treatment means. This implies that water hyacinth should be removed and another one re-introduction of new plants for phytoremediation of greywater is to be achieved.
