CO2-driven algae-bacteria granulation for biological nutrient removal from different treated sewage effluents: role of inoculum source and effluent type.
Residual nitrogen and phosphorus in treated sewage effluent (TSE) remain a critical barrier to safe water reuse in water-stressed regions. Algae-bacteria granular sludge offers a promising polishing technology, yet no prior study has demonstrated its feasibility using CO2 as the sole externally supplied inorganic carbo...
