Optimization of BPMED for the recovery of ammonia and citric acid from ammonium citrate scrubber effluents by response surface methodology

The excessive nitrogen in waterbodies, often caused by the discharge of ammonia-rich wastewaters, leads to eutrophication, disrupting aquatic ecosystems. Wastewater treatment plants play an important role in the removal and recovery of nitrogen from wastewater streams, thereby preventing pollution. Air stripping in combination with acid...

Effect of spacer thickness on the overall energy consumption of BPMED using ammonium sulfate solution

Removal of ammonium from simulated ammonium salt solutions was done using bipolar membrane electrodialysis (BPMED), without the use of chemicals. The effect of spacer thickness and open area on the overall energy consumption of BPMED to transport ammonium from the diluate was assessed in batch experiments. The electrochemical energy consumption...
