Membrane operations with the intrinsic characteristics of efficiency high selectivity and permeability for the transport of specific components compatibility between different membrane operations in integrated systems low energetic requirements good stability under operating conditions and environment compatibility easy scale-up and large operational flexibility represent an interesting answer for the rationalization of chemical and industrial productions Drioli Giorno 2010 . 5. Conclusion Today we can say that the theoretical means models and technological tools are available to address the wastewater management in the context of sustainable development starting by seeing it as a resource not to lose provided it is recovered in time. Year 2010 recent environmental disasters are proof that we must reconsider how the industries that use water as process fluid or generate wastewater must proceed. A plant must be regarded as a system subjected to analysis of the exergy balance. For a long time in Canada and worldwide the paper mills were established near rivers that carried the trunks of trees and supplied the mills large consumers of water and energy. But a simple balance shows and experience has shown it before the timber itself contains more water than is needed for the process and unused parts have sufficient heating value to operate the plant and even provide energy to spare. Some plants have shown that circuit closure was possible and co-generation is commonplace although there is still room for improvement. The storage of hazardous materials shall be subject to security criteria and restricted to minimum volumes. In the past and even now the custom is to subtract of the costs of production the costs of wastewater treatment considered to be prohibitive. Releases to the environment moves to areas of lesser geopolitical regulations hidden storage and number of irresponsible .
