The invention relates to a method and a device (1) for the treatment and conditioning of liquid waste (2), as well as to a hardened briquette obtained by this method, according to which the first waste emulsion (14) is created in an on-line tank (5, 6), which filled with a flow rate Q (m3 / h), which allows the waste to be introduced into tight contact with air (13) injected into the first area (8) of the tank, which has a small volume of less than 0.05 m3, with a flow rate Q '(Nm3 / h), with Q '> 5Q, to obtain the first emulsion (14), which is then transferred to the second zone (16) of the tank, which extends to a predetermined first length L1, and then discharged through a structural element that creates a pressure drop (18) into a chamber (19) extending over a predetermined second length L2. At least one flocculant (22) is injected to obtain a second coagulated emulsion (23), which is at least partially degassed. Then, the suspended material of the second emulsion thus obtained (23) is filtered off or decanted. |
