Comparative Phycoremediation Performance of Three Microalgae Species in Two Different Magnitude of Pollutants in Wastewater from Farmhouse

The cultivation of microalgae using urban wastewater as a nutrient substrate represents promising bio-refinery concept that can serve multiple purposes; indeed, it allows for the generation biomass, which be used various applications while meanwhile removing nutrients from wastewater. In this study, potential collected at two different time periods in farmhouse microalgal growth was assessed. Wastewater samples were treated on laboratory scale, inoculating reactors with common species, Chlorella vulgaris (CV) and Scenedesmus quadricauda (SQ), an autochthonous strain Klebsormidium sp. K39 (Kleb), directly isolated effluents same system. main aim study to compare microalgae’s performances terms re-mediation biomass productivity. first case involved effluent lower pollutant level, showed removal efficiencies range 57–63% total nitrogen, 65–92% phosphorous, 94–95% COD, 100% E. coli. second involving higher remediation three strains ranged 93 96% 62 74% 96 97% At end experimental trials, waters values pollutants suitable irrigation use, accordance environmental national legislation, established specific thresholds purposes.
