摘要：

The paper presents the results obtained at laboratory, pilot and demonstrative scale with granular activated carbon adsorption as a mean to obtain effluent suitable as water supply for textile finishing industries, that require very stringent limits in terms of COD and colour removal. Laboratory scale tests evidenced that the specific carbon adsorption capacity, both for COD and colour, is highest for a sand-filtered + clariflocculated effluent and lowest for the sand-filtered + ozonated secondary effluent. Pilot and demonstrative scale tests were performed on three filters (0.3, 0.3 and 20 m(3) of GAC each) fed with the full scale ozonated secondary effluent.
