| Abstract | Experiments with laboratory- scale reactors fed with vegetable oil wastewater were conducted to investigate the treatment potential of water hyacinth system. Oil and COD loading and hydraulic retention times were varied to determine the maximum and appropriate oil and COD loadings for the design of the water hyacinth systems. Hydraulic loading and water hyacinth density were also varied to determine their effects on treatment efficiencies. The results showed the maximum oil and COD loadings to be 140 kg/ha-d and 1256 kg/ha-d, respectively; at the point, water hyacinth could not tolerate. The oil and COD removal efficiencies were 92.7-97.98 and 84.4-98.8%, respectively, with oil loadings varied at 26-1-4 kg/ha-d and COD loadings varied at 90-932 kg/ha-d, and water hyacinth density was 15 kg per square meter. Oil removal efficiency with lower than that (same oil loading of 32 kg/ha-d) with the higher hydraulic loading (162 m3 / ha-d). Water hyacinth densities at 15 and 26 kg per square meter produced about the same effluent quality. |
