The aim of this research was to show the better use of internal resources and increased capability of utilizing and optimizing minerals. Also, in this research we tried to present a new way of petrochemical wastewater treatment. In this sample of bentonite, after the production process in microwave through digestion method with Nano Precision, a long chain of detergents was processed and optimized with an organic material (dimethyl octadecyl ammonium chloride). In the beginning of tests, a statistical method was drawn by MINITAB software and Taguchi method. Sampling was made in different times and testing started by a standard method. Among measuring factors, 5 factors of turbidity, TSS, TDS, pH, and COD were evaluated and their changes were investigated in different times based on the amount and type of materials. The effluent COD and BOD are very important. The petrochemical wastewater was measured and it was90ppm(COD) and 3 ppm(BOD). Also, the highestlevel of turbidity for material A (modified bentonite) was 1.2 NTU with 10mg/L of sludge. Considering that the country needed a better wastewater treatment through environment protection, modification of bentonite's structure, and nano application process in this industry along with various available methods, we aimed to take a step towards the development of the country.
