High technology of methane digestion of wastewater sludge with biomass recycling

Summary

The technology of methane digestion of wastewater sludge with biomass recycling developed at Mosvodokanal MPUE is presented. The technology advantages ensure reducing the dry weight of sludge compared to the traditional digestion due to deeper decomposition of ash-free matter, and saving the sludge transportation, dewatering and utilization costs. Introduction of the technology at large-scale facilities will provide for eliminating the problem of hydraulic overloading.

Key words

sludge , biogas , activated sludge , biomass recycling , methane digestion , thickening , specific resistance to filtration
