Treatment of Zagros Petrochemical’s Wastewater; Coagulation and Flocculation Method

Zagros Petrochemical Company, as one of the largest methanol companies in Iran, faces a problem ofhigh levels of turbidity, sulfate and ammonia pollutants in its wastewater. This research investigated thecoagulation and flocculation process and compared the efficiency of six different coagulants. The results showedthat polyaluminum chloride and polyelectrolyte coagulants reduce the pollutants, and when combined with limeat pH of ۱۲, significantly decrease turbidity and ammonia levels.
