Abstract

The invention relates to a method and a device for pretreating water when filtering in an anaerobic biological filter. The water is caused to pass through the treatment chamber 1, where nitrogen, which has recirculated via the pressure pipe 14, is caused to bubble up through water. As it does so, the nitrogen displaces the oxygen which is dissolved in the water. <IMAGE>
