Method and device for clarification of liquids, particularly water, laden with materials in suspension.

摘要

Procedure flotation clarification of water laden with suspended matter, characterized in that the clarification treatment takes place in two successive steps implemented in a single installation: - a step of static flocculation downdraft, at which a stage integrates primary separation of the heavier particles, the zone in which the primary separation step of the heavier particles situated under the zone in which the step of static flocculation is performed and comprising an evacuation of the heavier particles is carried out being being the settling velocities of the heavier particles retained during this stage static / primary, less than or equal to the settling velocities of the floatable particles separation flocculation and - one flotation step ensures the removal of light particles which settling velocity is below the threshold cutoff f lotador.
