Method for the disintegration sewage sludge

Abstract

There is a method for which a sewage sludge is permitted to flow from a first connecting region 21 to a treatment device, which works with rotation and stresses the sewage sludge with severing parts, and from the treatment device to a second connecting region 1. It is desirable to improve the continuity to the operation and to attain a decisive increase in the disintegration. This is achieved by using a rapidly rotating pipe-head formation, which has a head 6 with radial openings 10 and radial wings 4, for the mechanical disintegration of biogenic sewage sludge. The edges of the openings exert a shear effect, while the wings exert an impact effect and the combination of these two actions, in conjunction with the rapid rotation, brings about the improvement in the disintegration.
