Abstract
Membrane technologies, often hybridized with conventional operations, have been consolidated as techniques for separation, purification, and concentration of polysaccharides, phenolic compounds, and other bioactive compounds from wastewaters and by-products generated in the wine industry, as well as in other agro-industrial activities. However, in order to enable an efficient application of such technologies, some questions are crucial and must be properly approached in terms of the selection of membranes with appropriate characteristics and the optimization of operating conditions and fluid dynamics. Thereby, in this chapter is presented the role of membrane separation processes conducted by pressure gradients and its integration with conventional operations of extraction, separation, and purification of polysaccharides and phenolic compounds from winery wastewaters and from the extracts of by-products of the wine industry, focusing mainly on lees extracts.
