Study of Coagulant Development and the Characteristics for the Treatment of Tire Remanufacturing Wastewater


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.
