【 摘 要 】

Produced water, which is a mixture of organic and inorganic compounds, is a major wastestream generated in oil and gas industries. Its negative impacts on the receiving water bodies have become aworrisome environmental issue. The effluent quality of a crude Oil processing and exporting installation located inthe coastal area of the Niger Delta was studied for six months to ascertain the efficiency of the company’sproduced water treatment processes. Physicochemical parameters were monitored at the inlet and outlet of theproduced water treatment plant. Parameters examined were Temperature, pH, Oil and Grease, Total DissolvedSolids TDS, Total Suspended Solids TSS, Biological Oxygen Demand BOD5. The average temperature of theproduced water was reduced from 42.0°C to 25.9°C. The average pH of the samples, which was mostly alkalineprior to treatment, improved from 6.3 to 6.7. The Oil and Grease was reduced from 645.3mg/l to 8.2mg/l. Theaverage concentration of the TDS was reduced from 3836.2mg/l to 965.8mg/l, while the average TSS was reducedfrom 72.5mg/l to 31.0mg/l. The average Biological Oxygen Demand was reduced from 986.0mg/l to 92.0mg/l.The produced water treatment facility had capability of bringing the final effluent to dischargeable limit.
