Sep 12 2015
Prof Dheyaa Wajid Abbood, from EWERC, presents "Improvement of Wastewater Pretreatment for Refinery Using Different Types of Coagulants"
The refinery wastewater discharged from the Durah Oil company is evaluated to be 60 m3/hr, that consumes a large quantity of water. It causes high water pollution to Tigris river and the agricultural lands in Baghdad, the capital city of Iraq. The basic aim of this investigation is to modify the feasible and efficient method for treating oily wastewater. Measurements of wastewater such as turbidity, pH, and total dissolved solids, TDS, chemical oxygen demand, COD, total hardness, TH and oil quantity were achieved during period four months. Two coagulants were used in this experiments including Alum and mixture of Bentonite and Kaolin, the optimum alum dosages are (20, 40 and 80 ppm) and clay dosage is (2.5, 5, and 9 g/l) are required to treat wastewater for initial oil concentration (20, 40, and 136 ppm) respectively.
This talk will take place Thursday 19th November, 10-10.30am, Room 5.
