Treatment of Wastewater from Dye Industry
The characteristics of a coagulation process for the removal of colour from the organic dye industry wastewaters by inorganic coagulant or polymeric flocculant has been studied. Flocculation/precipitation was carried out using three coagulation agents to to wastewater samples: FeCl3 6H2O, Levafloc R and Colfloc 3915. The optimum pH range for decolourization with polymeric flocculants was found to be between 6 and 7 while with inorganic coagilant it was between 2, 5 and 4. Acceptable efficiency of wastewater decolourization, low total organic carbon (TOC)and chemical oxygen demand (COD) were obtained with 0, 1 M solution of Fe(III) as an inorganic flocculant. The addition of 1 % of volume fraction of liquid Levafloc R and Colfloc 3915 removed the colour almost completely.
