Organic compounds in industrial wastewater, slurry or digestate water hold huge energy potential. For example, the sludge water of a wastewater treatment plant or the slurry of biogas plants contain large amounts of nitrogen and carbon compounds.
Until now, this nitrogen and carbon load has had to be converted, i.e. purified, at great expense. In wastewater plasmalysis, these so-called pollutants, such as ammonium (NH4), are split into hydrogen and nitrogen.
Graforce membrane technology separates the gases and stores them in gas containers. The hydrogen can then be transported or used directly in the wastewater treatment plant in hydrogen CHP units for CO2-free power and heat generation.
What remains is purified water, which is returned to the water cycle, and nitrogen, which can be used as an industrial gas.
Operators of wastewater treatment or biogas plants thus benefit in two ways.
