چکیده

The presented article is attempted to use the nanoclay filter to provide the natural restrictor to prevent the spread of industrial effluents transmission channels related to Kaveh Soda company in Maragheh, northwest of Iran. For this purpose, a laboratory model has been designed to evaluate the performance ability of nanoclay filters to reduce soil permeability. In the experiment used 0%, 3%, 6% and 9% nanocaly contents specimens to create the filter columns which are performed by permeability test. In this test, the inlet fluid was the factory industrial effluent instead of water. According to the results, it can specified to the permeability coefficient was 3.18×10-4 cm/s (0% nanoclays) which decreased to 7.71×10-7 (9% nanoclays). This indicates the ability of the nano-filter to significantly reduce the permeability coefficient.
