Nanofiltration as a post-treatmento to membrane bioreactor effluent for dairy wastewater reuse

摘要

Among the food industry, the dairy industry is considered the most polluting one because of its high water consumption and generation of wastewater, which in turn constitutes the major source of pollution of this type of activity (VOURCH et al. 2008). These effluents are characterized by having high concentration of organic matter, grease, suspended solids and nutrients, and can cause major environmental problems when disposed of improperly (CAMMAROTA and FREIRE, 2006).
