A METHOD FOR REMOVING AMMONIUM NITROGEN FROM ORGANIC WASTE WATER.
The invention relates to a method for removing ammonium nitrogen from organic waste water, which method comprises the steps of applying waste water with a high content of ammonium to an organic, synthetic ion exchanger,allowing ammonium to adsorb to the ion exchanger, and regenerating the ion exchanger with regenerant solutions of very high molality.
The invention relates to a method for operating a biogas plant, which method comprises the steps of fractionating an organic waste material into a solid and a liquid fraction, leading the solid fraction to a biogas reactor, removing ammonium nitrogen from the liquid fraction, and leading a portion of the liquid fraction, from which nitrogen has been removed, to the biogas reactor.
The invention relates to a method for removing ammonium nitrogen from organic waste water comprising liquid manure, which method comprises the steps of applying waste water with a high content of ammonium to an organic, synthetic ion exchanger and allowing ammonium to adsorb to the ion exchanger.
