The invention concerns a method and an apparatus for removal of ammonium from a polluted media, which avoid the disadvantages related to the chemical-physical properties of MAP, with the aim to improve the technical and economical operational parameters and to produce a reusable and environmental friendly produced nitrogen fertiliser. The invention concerns a method and a apparatus where all chemical processes and mechanical steps are carried out in one single container with the different steps split in time phases, whereby the chemical products are prevented from transportation between compartments and contact with pumps and pipes. Only liquids without precipitates are in contact with these elements. The apparatus includes a process container, an elevator unit and a flexible membrane which together enables all chemical processes, separation, mixing and gas extraction to be carried out in the same compartment. The application is mainly for ammonium containing water from Leachate, reject water, food industry and agriculture.
