Abstract
Tannery wastewaters are exceedingly complex and characterized by high contents of organic, inorganic
and nitrogenous compounds, chromium, sulfides, suspended solids and dissolved substances. Treatment
of tannery wastewater was carried out by using activated carbon modified metal chlorides approaches.
Effluent from an existing tannery was used as the test medium. The characteristics of the influent and
effluent after the chemical treatment were determined. Modified activated carbon mixed with clarified
tannery effluent then the various constituents of the effluent were re-investigated. The results indicated
a very good deduction of physico-chemical parameters and heavy metals such as chromium were
gradually reduced with the introduction of 100-500 mg/L of activated carbon metal chlorides, including
CaCl2, which were 41% (EC), 76% (BOD), 47% (COD) (72%) (TDS), 87% (total hardness), 45%
(chlorides), 63% (sulphate), 58% (nitrates), 70% (Cr), 32% (surfactants).
