Phenols Removal from Wastewater - Samco Tech
Phenols Removal from Wastewater - Samco Tech

Phenols Removal from Wastewater. When refineries purify crude oil to be used in products, such as gasoline and diesel fuel, the raw crude oil has many contaminants that need to be removed such as ammonia and phenols. During the washing cycle, these phenols are removed from the crude oil and become attached to the water.
