tThe chromium (Cr) used in the manufacture of leather from hides has well-known adverseeffects when inappropriately disposed in the environment. The tanneries use large quanti-ties of water for processing hides. The recovery of Cr from the wastewater produced in thetanning step is an environmentally friendly and economically viable alternative avoiding thedisposal of large amount of Cr-containing sludge in industrial hazardous waste landfills. Thiswork aims at studying the removal of the Cr from the tanning wastewater through chemicalprecipitation (CP) and electrocoagulation (EC) techniques and its reuse in tanning process. Inthe CP experiments, efficient Cr removal from wastewater samples was achieved, with up to99.74% removal efficiencies. In the EC experiments, three different electrode materials, Al,Cu, and Fe were tested. The highest removal efficiency of 97.76% was obtained with Al elec-trodes by conducting electrolysis at 3.0 V for 110 min. This was followed by Fe electrodes andCu electrodes, which showed removal efficiencies of 90.27% (at 2.5 V) and 69.91% (at 2.0 V),respectively, for an electrolysis of 100 min. The recovered Cr was reused as a tanning agentin leather processing, where good crossing of Cr was reached in leathers tanned with theliquors prepared from the sludge, and the pH and ash content values were measured. Whilethe hides tanned with the Cr-containing liquor recovered by CP and by EC with Cu electrodesshowed good hydrothermal stability and Cr content above 2.5% Cr2O3, the hides tanned withCr-containing liquors recovered by chemical precipitation and by EC conducted with Fe andCu electrodes showed contents of Cr according to technical specifications. However, the Crsamples obtained with the iron electrode showed a dark coloration due to oxidation of theiron. It can be concluded that the tanning process with Cr recovered by CP and by EC withCu electrodes showed the best results.
