Tanneries generate large amounts of wastewaters that are characterized by high concentrations of organic matter, suspended solids, and sulfates. Then, reducing of water consumption and minimizing the pollution of the effluents are of paramount importance. In this chapter, firstly, a characterization of the effluents of a typical tannery producing leather from bovine hides is carried out. Afterward, the reuse of different residual floats is discussed by studying the environmental benefit and the possible effects on the final product quality. Finally, the implementation of membrane technologies is evaluated. For that, the use of membrane for the treatment of particular effluents from tanneries is reviewed, and after that, some practical experiences are discussed. |
