Abstract

The aims of this work were to characterization of industrial wastewaters such as dairy and steel manufacturing wastewaters, possible treatment processes, and reusing the treated wastewater for irrigation purpose was discussed. Fresh wastewater samples were collected from Yörüksüt Dairy Factory and Erbil Steel Company and analyzed for 21 water quality parameters. Chemical oxygen demand (COD), color, total suspended solids (TSS) etc. were exceeded the standards for disposal of wastewater. Thus, treatment processes are essential prior disposal of wastewater to the environment or using for irrigation purpose. Based on the characteristics of the wastewaters, the treatment processes such as primary, secondary and tertiary were discussed. In addition, the quality of raw wastewater samples and proposed treated industrial wastewaters were compared with the guidelines for the irrigation purpose.
