Chromium (III) salts used in tanning processes result in highly pollutant wastewater. Effluents from tanneries require comprehensive treatment due to the presence of dyes and other pollutants . The leather industry, a significant water consumer, uses dyes that are difficult to treat conventionally due to their complex structures and low biodegradability .
