【 摘 要 】

The wet market provided fresh foodstuff. Unfortunately, the sullage commonly discharged directly to the drainage without any treatment. Hence, this research was focused on culturing the Scenedesmus sp. and implemented the phycoremediation process to wet market wastewater and to measure the heavy metal removals by Scenedesmus sp. There are two different time collected samples: (1) Sample at 7 a.m. and (2) Sample at 9 a.m.. The five samples were collected for each time sampling from of the Parit Raja Public Market, Batu Pahat wastewater (with additional of five different concentrations of Scenedesmus sp. which are 1.235x106, 1.224x106, 1.220x106, 1.213x106and 1.203x106cell/ml). This experiment was conducted within eight days for culturing Scenedesmus sp. and phycoremediation within another eight days. The analysis was done with changes of DO and pH and heavy metals removal during phycoremediation. Based on the result, the optimum efficiency removals for each heavy metal had achieved (36.62-100%) and the optimum concentration for Sample 7 a.m. and Sample 9 a.m. is Concentration 1 (1.235x106cell/ml) obtained 81.18-100% of heavy metal removals. Concentration of microalgae is statistically correlated well with Fe (p0.05) in influencing high nutrient removal in the wastewater.
