Post-secondary treated WW was considered towards nutrient recovery for all scenarios except Scenario-II (MFC). The activated sludge process uptakes 62.3% of N and 37.4% of P, respectively. Sludge cake processing, post to anaerobic digestion has 15.4% N and 19.2% P. Thus, leaving behind 22.3% N and 43.4% P in the effluent (Figure ). This N and P after activated sludge process was considered for nutrient recovery using chemical precipitation, ion-exchange, and micro-algae systems. On the other hand, MFC works as a single-pot system to treat raw WW and recover nutrients at the same time (recovery rate = 80%) (Figure ). From MFC, N & P were recovered as nutrient-rich solution, which can be used as a raw material for fertilizer production. Scenarios III -V recovers N & P in the form of struvite, fertilizer crude, and microalgae biomass, respectively. Based on the type of nutrient recovery systems, the recovery rate of N & P varied between 11.3 -17.8% and 35.4 -36.4%, respectively (Figure ). This mass balance information of different nutrient recovery systems was used as LCI.
