ABSTRACT:
The invention serves for conditioning and sterilization of sludges originating from sewage treatment plants, and from water preparing plants, respectively, in such a manner, that both the homogenization and the mixing with coagulating agent of the sludge as well as the flotation separation of solid phase are carried out by ultrasonic treatment, while the microorganisms, among them also the pathogene ones, are decomposed. The conditioning agent added in the final phase of the ultrasonic treatment of a few minutes is metallic salt in case of biological sludges, and polyeletrolyte in case of sludges containing chemicals.
