Maximizing ammonium and phosphate recovery from food wastewater and incinerated sewage sludge ash by optimal Mg dose with RSM

Nitrogen (N) and phosphorus (P) removal and recovery as struvite from various waste streams have drawn much attentions for environmentally friendly and economically competitive fertilizer production. In this study, integrated approach of using food wastewater (FW) and incinerated sewage sludge ash (ISSA) as the alternative N and P sources and optimum Mg dosage were investigated for the first time to achieve maximal nutrient recovery as struvite...
