Wastewater from rubber processing factory was characterised for its pollution potential. Results of the raw wastewater show that the physicochemical parameters measured were all above regulatory limits for wastewater discharge in Nigeria. These high values for these parameters show that wastewater from rubber processing factory has high pollution potentials, and therefore need to be treated before discharge into the environment. Snail shell however proves effective in the treatment of this wastewater as it shows great improvement in the quality of the wastewater after treatment. Thermodynamic studies of the treatment show that the change in ?G of the parameters in the treated wastewater has negative values except that of pH and dissolved oxygen. The positive values indicate that their treatment was not spontaneous. The values of the change in ?S and ?H were positive for most of the parameters in the wastewater while few were negative.
