Abstract:

The aim of the study was to investigate the effectiveness of decolourization of various types of textile wastewater by coagulation with the use of chitosan while ensuring high process efficiency. The effects of decolourization depended on the composition and ionic nature of compounds present in the wastewater. Additional use of ferrous sulfate next to chitosan in the coagulation processes increased the level of wastewater decolourization to about 99%.
