The present research work focuses on Adsorption performance of Low-Cost Adsorbent Natural Clay. The adsorption of effluents on clay samples was examined. The samples of industrial wastewater were taken for this purpose including Chemical Manufacturing Industry, Textile Industries (Dyeing and Finishing), Dairy industry and Paper mill. Clay samples were taken from local areas of Gujarat, (Mostly from the area of Suredranagar). Chemical Analysis of all clay samples was taken to study their mineral composition. Effluent samples were treated with clay by shaking process. Different parameters of industrial effluents were analyzed and studied before and after the clay treatment and the difference between them was recorded In the present study Natural Clay was used as Low Cost Adsorbent for the removal of pollutants & impurities from industrial wastewater samples collected from six different industries. After review & verifying data & results it was concluded that Natural Clay can be used as an efficient & effective Low Cost Adsorbent for the adsorption of contaminants in the industrial wastewater. The color of the industrial wastewater samples can be colorless or lightened after adsorption which clearly means the colored or visible pollutant or compounds are adsorbed on Natural Clay adsorbent. Other parameters like, pH, Conductivity, Total Dissolved Solids (TDS), Chloride Ions, Hardness, Acidity & COD were determined before & after clay treatment. The results revealed that the Natural Clay could be used as an Adsorbent for the treatment of industrial wastewater as it is very cheap and has no hazardous side-effects. It effectively removes the pollutant & contaminants from industrial effluent.

Key Words – Natuaral Clay as adsorbent, Adsorption, industrial wastewater.
