pH: 8.5

COD: < 30 ppm

TSS: < 10 ppm

BOD: < 10 ppm

 AES Solution:

In order to properly handle the wastewater, two stages of aeration are used to drop the COD/ BOD, so it can reach low levels. Each Aeration tank has it is own clarifier and sludge recycling system.

The plant is equipped with equalization tank, sludge digesting facility, and manual and automatic inlet screens.

 Conclusion and Results:

Despite [...]

Project Briefing:

AES Arabia was awarded a contract by the Spanish EPC contractor TecnicasReunidas to supply a wastewater treatment plant for Petrokemya Acrylonitrile Butadiene Styrene polymer (ABS) Project located in Al-Jubail Industrial City, Kingdom of Saudi Arabia. The petrochemical plant is the largest ABS emulsion producing plant in the world with 140,000 Metric tons per year. The raw materials used in the plant are Styrene (SM), Ethyl Benzene (EB), Butadiene (BD), Acrylonitrile (ACN), and Methyl Methacrylate (MMA). The ABS emulsion product shall be of Molding/ Extrusion/ Pipe commercial grades.
