The aim of this work was to study algal floway (AFW) to treat urban wastewater and to evaluate biomass productivity, lipid contents and biodiesel production. The results indicated the seasonal average algae productivity of 34.83 g dry weight m2 d−1 with a nutrient removal rate of 2.52 g m2 d−1N and 1.25 g m2 d−1P while the lipid content ranged between 14 and 22% of dry cell weight with the highest lipid productivity of 9.29 g m−2 d−1 during summer. Biodiesel quality was superior during summer with high centane number and cold filter plugging point values. High eicosapentaenoic acid content was found during winter growth cycles. AFW algae community was dominated by pennate diatoms during all growing seasons. This study is one of its kinds in Indian wastewaters and it provides fundamental information for further optimization and use of AFW to treat domestic wastewater and to produce algae biofuel feedstock.

通过藻类流动法在城市废水中通过藻类培养生产生物柴油
这项工作的目的是研究藻类流动(AFW),以处理城市废水并评估生物量生产力,脂质含量和生物柴油生产。结果表明,季节平均藻类生产力为34.83 g干重m 2 d -1,养分去除率为2.52 g m 2 d -1 N和1.25 g m 2 d -1 P,脂质含量为14%至22%。干细胞重量,最高脂质生产率为9.29 gm -2 d -1在夏天。在夏季,生物柴油的质量较高,具有较高的庚烷值和冷滤器堵塞点值。在冬季生长周期中发现高二十碳五烯酸含量。在所有生长季节中,AFW藻类群落均以羽状硅藻为主。这项研究是印度废水中的此类研究之一,它为进一步优化和使用AFW处理生活废水和生产藻类生物燃料原料提供了基础信息。
