Evaluation of Wastewater Characteristics in the Urban Area of Sulaimanyah Governorate in Kurdistan-Iraq

Authors: Abdulfattah Ahmad Amin

Abstract:  The population of Iraqi Kurdistan region is increasing rapidly. This has increased pressure on water supply and waste water management in the region. The Sulaimanyah city and other cities of Iraqi Kurdistan region are facing serious challenges in this regard. The present paper aims to study the characteristics of waste water in Sulaimanyah city, its harmful effects on environment and how to deal with these problems in order to safeguard the city from environmental pollution. All important parameters such as biological oxygen demand, chemical oxygen demand, total suspended solid, turbidity and phosphorus of waste water study were found higher than standard value. Only pH value was found in a standard range. Two types of samples of waste water were collected (stagnant and running) from three different places in Sulaimanyah. The values of different parameters for these samples are: pH range was 7.57-7.06, conductivity range is 190- 813 μЅ/cm, turbidity range was 37-250 mg/L, dissolved oxygen (DO) range is 3.25-6.5 mg/L, biological oxygen demand (BOD5.) range was 18-58 mg/L, chemical oxygen demand (COD) range was 10-110 ppm, phosphorous range was 3.48 -6.26 ppm and total suspended solid (TSS) 84-284 mg/L. Such type of water is not suitable for vegetation and other agricultural purposes.

Keywords: Wastewater, BOD5, COD, Conductivity, TSS, Ph.
