Abstract (en)

[origin: WO2011055092A1] The invention relates to a device and a method for anaerobic treatment of wastewater in a biological reactor (100) involving at least one stabilised bacteria species including the following steps: measuring (150) a concentration, in an area linked to the reactor, of a reaction product inhibiting said at least one bacteria species; extracting (160) a fraction of the contents of the reactor when said concentration exceeds a predefined threshold; separating (300) said fraction into first and second sub-fractions, the first sub-fraction being depleted of said reaction product; and recirculating (310) the first sub-fraction in the reactor.
