Abstract
It has been stated that the use of complex titanium-containing agents can significantly increase the efficiency of wastewater treatment and achieve a reduction in residual concentrations of heavy metal compounds down to standard values. For further separation of coagulated sludge from purified water, it is proposed to use filtration methods with ceramic tubular filters. A significant increase in the filtration rate of titanium-containing coagulation sludge has been confirmed, leading to an increase in the productivity of treatment equipment by 20–30 %. It is recommended for purification of acid-base and chromium-containing wastewater to combine the process of coagulation of impurities by treating the wastewater with a complex titanium-containing coagulant, followed by filtering the resulting sludge using special ceramic tubular filters.
