RESEARCH OF THE EFFICIENCY OF THE DNIPRO RIVER WATER PURIFICATION USING WOOD MEMBRANES

The high efficiency of the tubular wood membranes (developed at A.V. Dumansky Institute of Colloid Chemistry and Water Chemistry of the National Academy of Sciences of Ukraine) in the process of Dnipro river water purification from suspended substances and Fe compounds as well as its disinfection to levels lower than exsisting norms for drinking water were shown. The possibility of reducing the content of Mn compounds and the color in the process of the river water treatment as well as the possibility of conditioning (post-treatment) of tap water were revealed. It was established that in the case of treatment of the river water using a wood memrane in the presence of a low dose of Al2(SO4)3, the specific productivity of the membrane was 3 times higher than the value of the same parameter in the case of treatment without the addition of coagulant.
