This study was conducted with synthetic wastewater from urea and ammonia (representing nitrogen fertilizer production wastewater) and additional carbon source of methane (CH4). Methane and air were supplied to microbial liquid phase using a bubble air stone aerator located at the bottom of a bioreactor with methane gas flowrate ranges from 1 to 2 L/h, air flowrate ranges from 3 to 6 L/h. |
