Assessment of biological treatability and advanced treatment of industrial wastewater (petrochemical sector)

Objective

Optimization of COD and nitrogen removal from complex wastewater.

Approach

• chemical and physical characterization of incoming and outgoing wastewater;
• assessment of wastewater biodegradability through respirometric tests;
• assessment of advanced treatments (adsorption-PAC, GAC, zeolites) and advanced oxidation (ozone) on the removal of organic contaminants.

Results

The wastewater is biologically treatable, but requires pre-treatment to reduce COD and nitrogen.
Advanced combined treatments are more effective for the simultaneous removal of organic contaminants.
