In this study, the reduction of organic pollutants from wastewater was investigated. Ultrasonic radiation was approved as the usage method. Effective parameters such as the period of ultrasonic radiation (10-35min), ultrasonic power (40-200watt) and initial organic material concentration (123-150 mg/l) were tested to determine their effects on organic material removal percentage and turbidity regress. It has been found that a time interval of 30 minutes of continuous exposition of dissolved organic material to the field of ultrasound come to 76% removal at initial organic material concentration of 123 mg/l. Significant temperature change occurred which was about (20-33) rise in 35 minutes. However, this temperature change had no significant influence on efficiency of the treatment .Also it was found that the turbidity deceases with time from 98 to 34 at 35 min of exposure to Ultrasonic irradiation.
