Abstract

Optimum parameters of the electrofl otation process removing of AL(OH)3 particles with direct dye adsorbed on its surface have been determined: current density - 10÷20 mAcm-2; the liquid layer height – 40÷50 cm; the process duration - 400÷500sek. That regime has been tested and confi rmed with the results obtained at the dry-cleaning and clothes dyeing factory. It has been shown that the degree of AL(OH)3 removing is about 95÷98%.
