  • Separation device
    Patent number: 4028256
    Abstract: A device for separating floating or precipitating components from a liquid comprising a number of substantially parallel inclined passages between superposed partitions, and provided with additional mutually parallel guiding baffles at least at one extremity of this assembly for guiding the liquid and/or separated components towards the effective part of these passages without restricting the cross-section of the assembly.
