Treatment of Secondary Sludge for Energy Recovery

  title={Treatment of Secondary Sludge for Energy Recovery},
  author={Charles Chunbao Xu and Jody Lancaster},
Primary and secondary sludges are produced as a result of primary and secondary wastewater treatment in municipal wastewater plant or pulp and paper mills. Sludge disposal has become a worldwide problem for many reasons including rapidly shrinking landfill space, increased environmental awareness, more stringent environmental standards governing the disposal of sludge, and dewatering challenges. Unlike the primary sludge, the secondary sludge as byproduct of the biological treatment is far more… 
Feasibility Study of Anaerobic Codigestion of Municipal Organic Waste in Moderately Pressurized Digesters: A Case for the Russian Federation
Anaerobic digestion (AD) is a promising option to obtain renewable energy in the form of biogas and reduce the anthropogenic impact on the environment. In recent years there has been increasing

Exploitation of Algal-Bacterial Consortia in Combined Biohydrogen Generation and Wastewater Treatment
The combined wastewater treatment and biohydrogen evolution approach applied green microalgae-based photoheterotrophic degradation using dark fermentation wastewater effluent as substrate showed that condition-dependent mutualistic relationships between the microbial and Chlorella algae populations had direct impact on the biodegradation efficiency and also on algal bioHydrogen production.


A new treatment of sewage sludge by direct thermochemical liquefaction
As one economical solution to the sludge disposal problem, the thermo-chemical conversion of sewage sludge to heavy oil was studied. In order to investigate optimum starting materials and catalyst

Decreased sludge production strategy for domestic wastewater treatment
Experiments with various imposed wasting rates showed that viability and sludge production yield decreased when sludge age increased and this work gives a new outlook on the AS process and leads to the development of processes with control and reduction ofSludge production.
