Wine effluents: treatment issues and initial assessment of the design and functioning of the biological processes.

Abstract

A wide range of processes is now applicable to the treatment of winery effluents and a specific methodology should be applied to choose the solution the most adapted according to the constraints (characteristics of effluents, quality required for treated waters, environment, storage capacity). The specificity of biological treatment applied to winery effluents is reminded as well as the possible performances. A wide development is given to the partial batch processes adapted to the small units of wine making, especially to the various systems associating aerated storage and various techniques of additional finishing treatment.
