Abstract

Source separated toilet water contains a high concentration of nutrients, which can be recovered to produce fertilizer products. To safely recover and reuse these nutrients, pathogens present in concentrated black water (BW; toilet fraction of domestic wastewater) should be removed. In this study, results showed that thermophilic (55 °C) and hyper-thermophilic (70 °C) conditions increase the removal of (antibiotic-resistant) pathogen indicator organisms, compared to mesophilic conditions. Furthermore, the potential of BW as source for safe nutrient recovery has been demonstrated.
