Database for total petroleum hydrocarbon in industrial wastewater generated at Sabhan area in Kuwait

A research study was carried out to collect data on the quality and quantity of petroleum and nonpetroleum industrial wastewater from different sources in Kuwait over a period of 1 y as well as developing a database of such characteristics and attributes using geographic information system (GIS) technique. During the field visits, a specially designed field surveys were submitted to the owners of industrial facilities in three industrial areas in Kuwait, namely, Sabhan, Kuwait City, and Shuaiba industrial areas. In this study, wastewater samples were collected and analysed on monthly and biweekly basis from 14 non-petroleum factories of Sabhan industrial areas. This paper was targeting assessment of total petroleum hydrocarbon (TPH) in the raw wastewater for factories of Sabhan industrial area. The field wastewater data indicated presence slightly acid to slightly alkaline (4.9–10.8), reduced to oxidized environment (–410 mv–538 mv) and freshwater to brackish water (120–8,673 μS/cm). The laboratory results revealed that total petroleum hydrocarbon concentrations for wastewater of 14 factories ranged between 0.3 and 19 mg/L. The mean values of total petroleum hydrocarbon concentrations for wastewater of 14 factories were meeting the maximum limit (5 mg/L) set by KEPA for irrigation water purposes except those values of TPH (>5 mg/L) for three factories. The mean value of quantities of wastewater generated from 14 factories was found 55,894 m³/week. The large quantities of raw wastewater generated from these factories can be used safely as irrigation water for landscaping and greenery with respect to total petroleum hydrocarbon concentrations.
