Recycling of Industrial Wastewater by its Immobilization in Geopolymer Cement

Abstract:

Article Preview

In this work, wastewater from Teva Pharmaceutical Industries Ltd., which comprises several organic and inorganic compounds, was solidified in a geopolymer matrix. The addition of wastewater to the polymerization mixture of fly ash based geopolymers yielded a high compressive strength of 50-75 MPa that is similar to that of wastewater-free geopolymer. The leaching of organic compounds from the matrix was examined and it was found to be negligible, about 0.2%wt, and comparable to the amount that leached from a geopolymer matrix made without wastewater. The results indicate that the immersion temperature and the time of immersion have negligible influences on carbon leaching.
