Description
Summary:Primary sludge from the sedimentation of wastewater from a pulp and paper mill was used successfully as 25 per cent of the feed material in hardboard production. Laboratory experiments also demonstrated that anaerobic digestion of the wastewater after primary sedimentation and before activated sludge treatment would be beneficial. About 55 per cent removal of COD resulted in 18 h at 33C. This would reduce energy requirements for aeration, provide methane, and reduce surplus biological sludge by 65 per cent. Mass balances are given.
