Abstract
A procedure and its corresponding device for chemical purification of wastewater by precipitation, especially chemical precipitation of phosphates and production of other flocculation processes, characterized in that the wastewater to be treated and the precipitant are directed to an area located at the top of a bucket and in which they are intimately mixed, the mixture is then directed downward through a flocculation zone until it reaches a sedimentation zone in which the flocculation sludge is deposited and the water devoid of of this mud is directed upwards to a zone of pure water that a partition arranged in the bucket separates from the mixing and flocculation zones.
