Forest Industry Wastewaters IV Selected Proceedings of the 4th IAWQ Symposium on Forest Industry Wastewaters, held in Tampere, Finland, 8-11 June, 1993

About this book

Research on water pollution control in the pulp and paper industry seems to be at a turning point. New production technologies developed in recent years are leading to greater economy in water use and the avoidance of the chemicals (such as chlorine) that cause the most troublesome effluents. However additional problems must now be tackled, eg. corrosion and the accumulation of compounds that impair product quality. Increasingly the need for innovation in external treatment is being replaced by a new focus on in-plant control and residues management that demands close collaboration between treatment process experts and specialists in pulp and paper making. This was the focus of the 4th Tampere symposium, at which two hundred experts from 24 countries considered the state of water pollution control in the pulp and paper industry. The papers selected for this volume cover: effluent-free production; effluents and biotransformations; environmental impact assessments; removal of chlorinated organics; enhanced biodegradation and removal of non-biodegradable residues; analysis, development and application of aerobic processes; nutrient control; and special processes.
