Algae-based sustainable approach for simultaneous removal of micropollutants, and bacteria from urban wastewater and its real-time reuse for aquaculture

摘要: Abstract Freshwater consumption by humans has reached its peak, magnifying a dearth to freshwater availability across the world. The rising demand for led an interest in using purified wastewater reuse. In this study, novel microalgal strain Pseudochlorella pringsheimii — Ind-Jiht-1 was assessed pilot-scale phyco-mitigation of various pollutants raw urban wastewater, including heavy metals as well antibiotics resistant bacteria. results appeared promising; technology achieved 83.2% reduction COD, 66.7% alkalinity and 69.6% hardness. Moreover, almost complete reductions total bacterial coliforms could be achieved. Three isolates viz., IS-2, IS-9 IS-10, which were obtained even after 14-days microalgal-treatment wastewater. IS-2 most dominating species able thrive treatment. treated used cultivate sucker fishes. Bodyweight fishes measured evaluating their growth rates. average survival rates fish 0% 84%, respectively. Results confirm that algae-based not only reduces micropollutants bacteria from but also offers platform reuse water low-cost cultivation.
