Effect of Ultrasound Technology on Organic Pollutants, Electrical Conductivity and pH of Industrial Wastewater from a Tanning Plant in Mosul City

Section: Research Article

Abstract

     Research has included using ultrasound technology to treat industrial wastewater, which is the final output of the tanning plant in the tannery area before it is discharged into the Tigris River with Mosul City in January 2024. Analyzed chemical oxygen demand (COD), electrical conductivity (EC), and pH for samples. The results of the analyses showed the height that the chemical oxygen demand (1027 mg/L) and electrical conductivity (13014µS.cm-1) are beyond the maximum allowable limits. While the pH was within the standard level before exposure to ultrasound. The results showed a decrease in chemical oxygen demand when exposed to ultrasound, while exposing the sample for the same time increased the (EC), as well as the increased pH values. The efficiency of removing organic pollutants increases with increasing time, starting with (19.08%) at a time of two minutes, and ending at (32.22%) at a time of ten minutes.
