Abstract

Device in installations for biological purification of wastewater by the active sludge procedure, which consists of a tank, which seen from above has a circular shape, and which is divided by an immersion partition into a ventilation chamber located in the center and in a subsequent clarification chamber that in longitudinal section has a triangular shape and that surrounds it in an annular shape, as well as a high-power centrifuge located in the center of the aeration chamber and provided with a vertical tube that ends slightly above the bottom of the tank, several horizontal path pipes ending with an adjustable height in the area of the water surface in the subsequent clarification chamber, coupled to the vertical tube, characterized in that in the immersion wall in the area immediately below the surface of the One or more circular openings are provided to which spill pipes are attached arranged in the posterior clarification chamber and ending at the bottom of it.
