Effects of ultrasonic irradiation on raw rubber mill effluent.

Ultrasonic irradiation, an interesting and promising application, is useful as a new technique for degradation of organic compounds. The effects of ultrasonic irradiation in raw rubber wastewater is investigated at different operating conditions, namely, power density, varying pH, and the presence o...
