The present invention relates to a hydrofoil impeller for agglomerators in which agglomerator impeller blades are hydrofoils in a vertical agglomerator, which is frequently used in agglomeration basins of waterworks or sewage treatment plants, and a cylindrical tube or cone. Focusing on the shape of a specific part on the surface of the large pipe, the impeller blade is composed of a wing piece made by cutting and processing a required part on a specific part of the surface of a cylindrical tube or a conical tube. It is fixed to the vane at a predetermined elevation of the wing tip, so that the impeller wing's inner and exit angles and the outer mouth and exit angles, as well as the camber and the wing's position, provide the impeller for the agglomerator precisely.
