A kinetic model for anaerobic digestion of biological sludge
Abstract. The results of this study indicate that hydrolysis of the dead, particulate biomass—primarily consisting of protein—is the slowest step, and therefore kinetically controls the overall process of anaerobic digestion of biological sludge. A kinetic model was developed which could accurately describe digester performance and predict effluent quality.
Lime Slakers Ball Mill Slaker by Chemco Systems
Chemco supplied vertical ball mill slakers (The Union Process CLS Attritor) produce quality hydrated lime from commercial grade quicklime. Slakers are used to convert Calcium Oxide to Calcium Hydroxide for use in neutralization and pH control. Grinding action of the media eliminates the need for grit disposal.

Microbial growth reduction in sewage sludge by stirred ...
of a ball mill and a cutter mill. Of the two methods employed, it was found that ball milling yielded better disintegration results, perhaps due to the sequential process: breaking up microbial cell walls, releasing intracellular carbon compounds and nutrients for further anaerobic digestion. Mueller19 investigated
