Treatment of highly concentrated dye solution by coagulation/flocculation-sand filtration and nanofiltration

Treatment of highly concentrated C.I. Acid Black 210 dye solution using direct coagulation/flocculation–sand filtration (without sedimentation) and nanofiltration has been investigated in this paper. It was found that none of the treatments were able to fully decolourise the dye solution, but nanofi...
