Abstract (en)
[origin: WO2012175489A1] The invention relates to a process for treating wastewater containing organic matter within a reactor accommodating biomass granules and provided with aeration means. According to the invention, such a process includes a plurality of consecutive cycles, each of which include: an anaerobic step of feeding wastewater into said reactor, during which said water is mixed with said granules so as to form a fluidized bed; an anaerobic step of stirring the contents of said reactor; a step of aerating the contents of said reactor; a settling step; and a step of discharging treated water free of organic matter.
