The accurate, the city Touggourt is a huge mine of clay minerals, mostly exploited in the traditional pottery industry, ceramic and brick. The purpose of this work is to value these minerals in the field of environmental conservation by using them in wastewater treatment., in the first step, we determined the clay ratio in the soil where found 52%. The study of physical and chemical properties by XRD and FTIR showed that the clay is a mixture of kaolinite and illite also we found the surface area specific 113.76 m3/g, the cation exchange rate is 20 mm/100g. The second step is studies the adsorption of organic and inorganic pollutants in wastewater.
At the ideal conditions Vs= 700 rpm, Tc = 90 min, m= 1.5 g, pH= 8.1, T= 41°C, we got the following results COD = 69.16%, BOD5 =71.59%, P-PO4–3=73.10%, TSS =85.81%.
