Article Preview

This study was conducted to test the performance of various combinations of coagulants for effective wastewater treatment of the tire recycling industry. From the Jar-test results, two kinds of coagulants, namely AlSi-1 and PASi-1, were found to be effective in decreasing BOD and CODCr values from the polluted wastewater among various combinations of coagulants. In comparison to Al-based or Si-based singular salts, the Si-Al combined salts (PASi-1) exhibited a higher removal efficiency of 90% turbidity, 93% SS, 70∼85% BOD5 and 85∼91% CODCr at 15± 2°C, pH7.5∼9.5 and 2.0mM of coagulant dosage. At 30±2°C of tire recycling effluents, the combination effect was clearly shown in the removal of CODCr over a wider range of pH. The reaction mechanisms of AlSi-1 and PASi-1 were also schematically studied.
