Pharmaceutical Industry Wastewater Treatment by Electrocoagulation and Miceliar Ultrafiltration

The objective of this paper consists in pursuit the efficiency of electrocoagulation and micellar ultra filtration in terms of color removing, respectively, organic load, found in the final quality of the effluent, which must be within the limits imposed by the regulations NTPA 001 or NTPA 002, considering the company's options regarding recycling or reuse of water. In this work paper were determined: the electrocoagulation and micellar ultrafiltration performance evaluation was analyzed in terms of the main operational parameters influence: pH, current density, working pressure, surfactant nature and concentration, the anode nature and composite membrane nature; the best results for electrocoagulation were obtained in the following experimental conditions: pH = 5, i = 13.94 mA/cm(2), anode material: iron. In this combination was possible to obtain color/organic matter efficiencies of about 99%. The best performances for micellar ultrafiltration were obtained with: membranes based on 12% polysulfone and 2% polyaniline in dimethylformamide, surfactant:SPAN 80 at 104 Mat a pressure of at least 4 atm and pH = 9.2
