In agriculture, the human urine could have been used as a natural fertilizer, although there are some problems with direct utilization, such presence of micropollutants in urine, odour and storage large volume urine. Therefore, nutrients, nitrogen, can be recovered from Continuous flow laboratory membrane reactor was built to investigate nitrogen recovery wastewater Membrane gas separation method has not investigated for ammonia yet. Nitrogen acid using Zeus Aeos™ ePTFE gas-permeable hydrophobic membrane. Acid flux, operating pH, hydraulic retention time effective surface were experimentally determined. The aim this work verify experiments professional flowsheet environment, rigorously modelled ChemCAD optimized by dynamic programming optimization method: separation. Such published environment objective function process is harvesting efficiency. Eighty-five percentage efficiency reached 60 area/reactor ratio, at 35 °C feed temperature 350 L/m2h 8 h' time. It stated that based on physical phenomena without any biological factors. focus treatment plant removal instead recovery. determined system capable wastewater, it reduce content too.
