Title: SYSTEM AND METHOD FOR PURIFYING AN AQUEOUS FLOW CONTAINING URINE, AMMONIA AND/OR ORGANIC SUBSTANCE AND METHOD FOR PRODUCING HEAT AND NITROGEN GAS UNDER PRESSURE
Abstract:
The present invention relates to a system and method for purifying and/or treating an ammonium-rich organic waste and/or waste water flow. The invention also relates to a method for producing a nitrogen gas. The system according to the invention comprises: a closable pressure vessel provided with an inlet for supplying a flow to be purified and/or treated, wherein the pressure vessel is configured to perform an anaerobic conversion of the flow to be purified and/or treated to, among others, nitrogen gas, at least one outlet for discharging products from the pressure vessel, a control system for controlling the process on the basis of the relation between produced nitrogen and required oxygen, and energy generating means for regulating and/or generating usable energy with at least a part of the formed nitrogen gas.
