- Abstract
The aircraft factory maintains and paints the exterior surfaces of the aircraft structures. This work aims to treat the industrial wastewater of the aircraft factory. The concentration of phenol and chemical oxygen demand (COD) in industrial wastewater reached 125 and 11,763 mg/L, respectively. While the allowed limits for discharge on sewerage systems are 1,100 and 0.05 mg/L for COD and, phenol respectively. Fenton oxidation reaction (FOR) in addition to sawdust and date stone was tested for treating the wastewater. The effluent of the FOR was complying with the National Regulatory Standards. Another approach is to apply the pollution prevention concepts to remove the paint with the paint remover layer with the dry leaching. The suggestions were extended to the modification of the liquid waste collection tank to separate the floating matter in wastewater. The concentrations of phenol and COD were reduced from 125 and 11,763 mg/L to 0.04, and 985 mg/L, respectively. While the final concentrations of the phenol and COD were 0 and 572 mg/L in wastewater mixed with industrial wastewater from all the factory's sections. Thus, the industrial wastewater from the aircraft factory has become conforming to the National Regulatory Standards for discharge to the sewerage network.
