The environment, as a consequence of industrial and agricultural revolutions, tends to harden with potentially carcinogenic and mutagenic halogen-substituted aromatic compounds. Phenol and its higher molecular homologues are dangerous environmental pollutants. Due to their toxic character, these molecules tend to accumulate in water and soil after being discharged without an adequate treatment....

Introduction: Surfactant or surface active agents are slightly soluble in water and cause foaming in waste treatment plants and also in the surface waters into which the waste effluent is discharged. During aeration of wastewater, these compounds collect on the surface of the water bubbles and create some problems in waste treatment. Methods: In this study, surfactant, turbidity and COD in the...
