Petrochemical wastewater contains harmful organic and inorganic pollutants, posing risks to soil, water, and human health.
This study aims to recover valuable aromatics (like benzene and toluene) and water from this wastewater while removing toxic heavy metals through a specific treatment process using sodium bicarbonate.
The effectiveness of the process was confirmed through Aspen Hysys simulation and lab experiments, achieving over 99.5% removal of heavy metals, highlighting the potential for recycling and sustainability in petrochemical industries.
