ABSTRACT:
The present invention relates to a continuous filtration device in a liquid path, characterized in that it comprises, in combination:a modular ultrasonic treatment unit (12) which is in the form of a tubular metal body (11) with a cylindrical internal surface (13) and of circular cross section, open at both its feed end (10) and its discharge end (15), the external surface of the said tubular metal body having, in the vicinity of the nodal zone, a collar (17) which is coaxial with the said tube and which projects radially, this collar being equipped at its periphery with an ultrasonic converter (19) which projects radially and whose frequency is equal to the vibration frequency of the said collar (17) and to the longitudinal vibration frequency of the said tubular metal body (11), anda filtering cylindrical element (14) having a minimum filtration area of about 50 cm2and preferably about 80 cm2with a mesh opening less than about 20 μm, which is arranged inside the tubular metal body (11) and coaxially with the latter between its feed end (10) and discharge end (15),the nominal ultrasonic power density dissipated inside the tubular metal body being greater than about 2 watts per cm2of filtering area.
