Abstract

Improvements in the construction of aeration and ventilation devices for the biological purification of waste water, of the type provided with a paddle wheel that rotates around a perpendicular axis, partially protruding from the water level and with paddles arranged in approximately radial position and that it draws the circulating water through a conductive tube and ejects it by centrifugal force radially above the funnel of the conductive tube, characterized in that the width of the angle arms of the pallets flexed in the form of a gutter, seen from the hub, first increases and then decreases again until the end of the blade, the ends of the blades being inclined against the direction of rotation of the blade wheel and raised relative to the horizontal.
