Abstract | Two raw untreated tanning effluents were initially tested for the removal of COD, BOD, TOC, total and specific phenols, oil and grease, and total chromium, using the following six individual powdered activated carbons (PAC): ICI-HDC, ICI-HDH, Nuchar SA-15, Amoco PX-21, Norit FQA, and Westates WO-841. The first three carbons were subsequently tested for the above parameters on eight additional effluents, representing a total of six tanning subcategories. The carbon dose range investigated was 0.3 to 10 g/l. Final comparisons between the carbons were performed in terms of their removal efficiencies and ultimate capacities, using Freundlich adsorption isotherms. |
