Abstract

The invention relates to an effluent filtration device, in particular for effluents containing a fatty fraction, wherein said device includes at least a housing (2) in which at least one filtration sieve (3a, 3b) is provided and through which the effluent flows by gravity, said sieve separating the two chambers (8a, 8b) of the housing. The device is characterised in that it comprises a circulation means (15, 17) for directing towards the upper chamber (8a, 8b) above the sieve (3a, 3b) the effluents from a lower chamber (8c) underneath the sieve, the device further comprising effluent heating means (13, 14).
