PROCESS AND DEVICE FOR TREATMENT OF AN ORGANIC EFFLUENT. The present invention relates to a process and a device for treating an organic effluent (2, 31). The effluent is fed in continuous flow at a flow rate q(m3/h), via a first compartment (5) maintained at a first determined pressure (P1) and/or directly through a first restriction (7), a second compartment or container (10, 33, 55) maintained at a determined second average pressure (P2; P'; P1", P2'') by injecting air (1l, 3l, 54) into this second compartment at a flow rate Q (Nm3/h), to obtain an emulsion (13, 57) in this second compartment, a pressure drop (1) is created, determined in the emulsion eventually modified by a second and/or a third restriction or a valve (61 ) supplying a third compartment (22, 39, 62) maintained at a predetermined third pressure (P3; P'', P1'') in the zone (79) 20 located immediately downstream of that second or third restriction and/or valve (61) and a flocculant (24, 45, 78) is injected into this area of the third compartment, then this emulsion is degassed at atmospheric pressure and the emulsion is recovered, thus gasified in a filtering or decanting device. |
