Solar homogeneous catalysis to the removal of organic matter from slaughterhouse effluents undergone to a prior biological process

This study shows the effectiveness of the wastewater treatment from a municipal slaughterhouse that has undergone a previous biological treatment applying a sequence of stages, reaching a 75% of elimination of the chemical oxygen demand (COD) using sedimentation in combination with coagulation–flocc...
