Abstract

The invention relates to a process for removing phosphorus and nitrogen from waste water. Waste water from a conventional sedimentation step is subjected to the action of anaerobic bacteria in an anaerobic reactor, with phosphorus being released in the form of phosphate ions and nitrogen being released in the form of ammonium ions, after which the water from the anaerobic reactor is treated with magnesium ions and phosphate ions in a precipitation step in order to precipitate out both the ammonium ions and the phosphate ions in the form of struvite. <IMAGE>
