The pulp and paper industry generates large volumes of highly heterogeneous waste waters containing compounds from wood or other raw materials, process chemicals and compounds formed during processing.
The waste water streams from pulp and paper vary greatly in concentration and composition. The waste water from mechanical pulping (TMP) and secondary fiber pulping as well as the condensates from chemical and semi-chemical pulping are typically non-toxic to methanogenic degradation and contain easily degradable organic compounds.
Amongst various anaerobic systems, the UASB and EGSB processes are the most applied anaerobic reactor systems in the pulp and paper industry.
The Upflow Anaerobic Sludge Blanket (HydroThane STP® UASB) process and the External Circulation Sludge Bed (HydroThane STP® ECSB) process from HydroThane are worldwide proven processes for the treatment of this type waste water.
