The filtration device (10) according to the invention comprises a series of filtration cartridges (16-21) which are advantageously housed inside of a suitable container and which have different characteristics in accordance with both the type and the dimension of the element which are normally present in the waste liquids of either an odontotechnical or an odontological dentist's surgery, as well as a membrane self-priming pump suitable for being activated in an either automatic or semi-automatic way starting from an either manual or pedal command. According to the invention, said device (10) is placed downstream of the discharge hole (13) through which the liquid is evacuated, and of a possible decantation tank in which a suitable additive enhances precipitation of heavy particles. According to an advantageous feature of the invention, a membrane self-priming pump (15) is activated either in an automatic or in a semi-automatic way when the discharge hole is opened. <MATH>
