Beschreibung

This book covers bleach plant effluents, that most polluting effluent from the pulp and paper industry. Disappearance of benthic invertebrates, a high incidence of fish diseases, and mutagenic effects on the aquatic fauna are some of the consequences of the disposal of bleach effluents into surface waters. This book describes environmental impact of bleach plant effluents, environmental regulations, and measures to reduce the pollution load by internal process modification and external treatment of bleach plant effluents.

Covers emerging technologies in waste water treatment

Gives detailed practical information

Cites real-world mill experiences
