The Taman Process: Experiences of Full-Scale Operation at Anjala Paper Mill Available to Purchase

The first full-scale anaerobic waste water treatment plant in the Finnish wood processing industry has been completed at Anjala Paper Mill. This TAMAN process together with the extensive renewal of the water circulation systems as well as solids recovery have made it possible to meet the new environmental requirements coming into force in June 1987. The total BOD₇ reduction due to this investment program is nearly 90 %. The waste water flow through the TAMAN process is 11000 m³/d. The specific water consumption of the debarking plant has been minimized and circulation water is clarified in a separate settler. TAMDEC gravity thickeners make solids retention more effective and the TASSTER screw press ensures that all the mill's sludge is dewatered before fluidized bed incineration.
