A Suggestion on Nutrient Removal/Recovery from Source Separated Human Urine Using Clinoptilolite Combined with Anaerobic Processing

Abstract

Source separated human urine is a renewable alternative source of fertilizers. Plant nutrients therein may be concentrated upon clinoptilolite to be made available to plants in due course. The remaining liquid phase is a saline solution containing appreciable amounts of organics which may be converted into biogas to be used as energy while it is treated anaerobically. The preliminary results reveal that in addition to high levels of nutrient recovery and considerable organics removal, the remaining liquid waste may possibly be treated using anaerobic processes and that the outcomes can be improved especially after determining the best choices for process variables.
