Effluent discharge from textile industries to neighbouring water bodies and wastewater treatment systems is currently causing significant health concerns to environmental regulatory agencies. This study records lab scale experiments to test efficiency of cement kiln dust (CKD) and CKD + Coal filters in removing a colour, turbidity, and organic substances (BOD and COD) and heavy metals from textile wastewater. The results showed that the negligible difference between the CKD filter at hydraulic loading 0.5 and 1.0 m(3)/m(2)h in the removal efficiency COD and colour and increasing of seed germination for treated of textile industrial effluents. The higher efficiency of CKD + Coal than CKD filters for COD and colour removal of textile wastewater at hydraulic loading of 1.0 m(3)/m(2)h. CKD + Coal filter could remove about 97% of colour, 76% of turbidity, 84% of COD, 77% of BOD and 94% of PO4-3 from raw textile wastewater and it's increased in seed germination of cress (Lepidium sativum) to 100%. The experimental results confirmed that CKD + Coal filter can be adopted as a decolorization and heavy metals of textile industrial effluents. Crown Copyright (C) 2010 Published by Elsevier B.V.
