| Abstract | The phytoremediation of residential and surimi wastewater by water hyacinth, Eichhornia crassipes (Mart.) Solms, was investigated at a wastewater concentration of 1050% (v/v). The pH, biological oxygen demand (BOD), chemical oxygen demand (COD), total suspended solids (TSS), total kjeldahl nitrogen (TKN), and total phosphorus (TP) levels of each wastewater before and after phytoremediation were determined on day 0, 3, 6, 9, 12, and 15. The relative growth rate (dry weight) of the plant biomass increased from day 015 and depended on the wastewater concentration. The maximum growth of water hyacinth grown in 50% (v/v) residential or surimi wastewater over 15 day was 42.4 ? 1.5% and 41.7 ? 1.9%, respectively. After treatment with water hyacinth, most of the wastewater parameters were significantly decreased in according with a logarithm model (R2 greater than 0.84) at every tested concentration of both residential and surimi wastewater. The greatest removal efficiency of BOD, COD, TSS, TKN, and TP in 10% (v/v) residential wastewater was 90.1 ? 3.7%, 85.1 ? 4.2%, 85.5 ? 2.9%, 61.4 ? 1.9%, and 85.3 + 2.9%, respectively, while for 10% (v/v) surimi wastewater was 90.6 ? 4.7%, 83.7 ? 3.9%, 87.5 ? 4.1%, 62.3 ? 2.8%, and 82.1 ? 2.3%, respectively. Thus, phytoremediation with water hyacinth is an effective and alternative method for treatment of contaminants in wastewater. |
