Abstract
In this study an algabased simultaneous process of treating swine wastewater SWW and producing biodiesel was explored Chlorella vulgaris UTEX265 was employed as a model species and a SWWbased medium was prepared by dilution with tap water Chlorella vulgaris grew well in the SWWbased medium and at optimum dilution ratios it exceeded the conventional culture medium in terms of biomass concentration and productivity In eightfold diluted SWW which supported the maximum growth biomass productivity was 0247 g L−1 day−1 while the productivity was merely 0165 g L−1 day−1 in standard trisacetatephosphorous TAP algal medium In addition fatty acid methyl ester FAME productivity was greater in the SWWbased medium 0067 versus 0058 g L−1 day−1 This enhanced productivity resulted in more than 95 removal of both nitrogen and phosphorous All these show that C vulgaris cultivation is indeed possible in a nutrientrich wastewater with appropriate dilution and in so doing the wastewater can effectively be treated
