Synergistic cooperation between wastewater-born algae and activated sludge for wastewater treatment: Influence of algae and sludge inoculation ratios

► Cultivate algal-bacterial system with microorganisms from wastewater plant. ► Enhance biomass settleability with activated sludge. ► Enhance wastewater treatment efficiency at proper algae/sludge inoculum ratios. ► Identify the microbial consortium in cultures with different inoculum ratios.
