Preliminary study on greywater treatment using water hyacinth

摘要: Greywater constitutes a major portion of wastewater generated from domestic units. treatment through natural system provides sustainable method management. The objective this study was to evaluate the potential water hyacinth as phytoremediation aquatic microphytes for greywater based on optimum growth and harvesting frequency. operated in continuous mode 30 days. physicochemical properties treated physical characteristics were determined. physiochemical parameters influent greywater: temperature (23.1–24.9 °C), pH (6.94–7.94), total dissolved solids (192–648 mg/L), turbidity (9.8–49.9 NTU), chemical oxygen demand (51.2–179.2 mg/L), ammonium–nitrogen (2.8–6.16 mg/L), phosphate–phosphorous (0.45–1.168 mg/L). results showed an average removal ammonium–nitrogen, phosphate–phosphorous, 63.26 ± 10.47%, 61.96 ± 12.11%, 51.91 ± 5.32%, respectively. A 75% increase biomass observed during which may be attributed dense roots, hyperaccumulative properties, rapid rate hyacinth. interval 15–20 days recommended efficient performance. However, feasible methods need developed removing only matured mother plants, leaving baby system. Water found plant treatment, providing consistent quality water.
