Pulp and paper mill effluent management.

This is a review of the literature published in 2018 related to the prevention of water pollution by or recovery of beneficial materials from wastewater produced in the pulp and paper industry. This review includes the following main sections: cleaner production, biological treatment, and physico-chemical treatment. PRACTITIONER POINTS: Converting pulp and paper treatment sludges to value-added materials can be efficient cleaner production technique. Modeling and dynamic simulation techniques of biological treatment along with optimization methods can improve the effluent quality out of a paper mill. Hybrid treatment systems can have a synergistic effect on the treatment of pulp and paper effluents.
