Sludge minimization technologies--an overview

Various sludge disintegration technologies for sludge minimization are discussed, including mechanical methods (focusing on stirred ball-mill, high-pressure homogenizer, ultrasonic disintegrator), chemical methods (focusing on the use of ozone), physical methods (focusing on thermal and thermal/chemical hydrolysis) and biological methods (focusing on enzymatic processes).

Disintegration of sewage sludges and influence on ...

01/01/1998· The excess sludge was disintegrated by a stirred ball mill (Netzsch, LME 4), a high-pressure homogenizer (APY-Gaulin, LAB 60), an ultrasonic homogenizer (B. Braun, Labsonic L) and a shear-gap homogenizer (lKA, Ultra Turrax T25). The excess sludge was treated with different operational parameters. The duration of grinding, the agitator speed and the size of the grinding beads of the stirred ball mill …

Mechanical disintegration of sewage sludge.

An optimum of the bead diameter and the stress intensity in stirred ball mills could be detected. A comparison of the results of different methods of sludge disintegration shows that the investigated ultrasonic homogenizers are inferior to a high pressure homogenizer and a stirred ball mill in terms of energy consumption.

Methods to describe the degree of cell-disruption were developed and the release of organic components into the sludge water was measured. The best results were optained using a stirred ball mill and a high-pressure homogenizer. The influence of disintegration rate and digestion time on the performance of the anaerobic process and the dewatering characteristics were investigated. The degradation is …
