Selective Transport of NH₃ by Silica-Based Ceramic Pervaporation Membrane

Nitrogen (N) removal is one of the key tasks for every wastewater treatment plant under the growing pressure of environmental protection. Prevailing applied N treatment technologies are mostly energy-intensive. This dilemma triggers a rethinking of the way to approach N management. “N2kWh-From pollutant to power” is a project that aims at...

Electrodialysis with bipolar membranes for ammonia recovery in wastewater: An innovative concept for the treatment of ammonia residual streams

Municipal and industrial wastewater contains a significant amount of dissolved nitrogen. This is the results of the organic protein degradation and of the large employment of nitrogen (<i>N</i>), usually in the form of ammonia (<i>NH</i>₃), in the industry. Currently, nitrogen is removed in wastewater treatment plant (WWTP) by means...
