Abstract

Phycoremediation using microalgae has high potential for reducing nutrient load in public market wastewater (PMWW). However, the reduction efficiency depends on the initial concentrations of microalgae and PMWW. In the present study, the reduction of total nitrogen (TN), total phosphorus (TP), and total organic carbon (TOC) in PMWW using Scenedesmus sp., was investigated as a function of different PMWW concentrations. Scenedesmus sp. was inoculated with 106 cell/mL into 500 ml of PMWW and incubated outdoors under full sunlight for 19 days. The results revealed that higher microalgae growth was recorded in PMWW than in Bold’s basal medium (BBM). The maximum reduction values of nutrients were 91.51% for TN, 92.67% for TP, and 90.2% for TOC were achieved by 50% of PMWW. The findings indicated that phycoremediation with Scenedesmus sp. can successfully reduce the nutrient load of PMWW.
