Abstract (en)
[origin: WO2020114979A1] Water treatment method for simultaneous abatement of carbon, nitrogen and phosphorus, implemented in a sequencing batch moving bed biofilm reactor (SBMBBR) comprising supports suitable for the development of a biofilm. The method comprises sequences of successive treatments, each treatment sequence comprising: an initial phase of anaerobic treatment, said initial phase of anaerobic treatment being followed by at least one aerobic/anoxic cycle consisting of: an aerobic treatment phase so as to obtain an ammonium ion concentration that does not pass below a threshold concentration of ammonium ions; and, a phase in which the biofilm is placed, at least locally, under anoxic conditions, this phase being concomitant with or posterior to said aerobic treatment phase; the threshold concentration of ammonium ions being calculated to allow the development of anammox microorganisms during the phase in which the biofilm is placed, at least locally, under anoxic conditions.
