Introduction of a Novel Method for Treating of Drilling Waste Water

Mahmood Atefatdoost and Farshad Farahbod*

The performance assessment of Nano ferric oxide and mixtures of it (10 and 15 gr/lit) which contain mineral coagulants (5, 10, 15 and 20 mg/lit) as auxiliary coagulants in pretreatment of drilling waste water is considered, in this pilot scale experimental work. Major parameters in coagulation and flocculation such as total hardness, turbidity, amount of poly cyclic aromatic hydrocarbon, total petroleum hydrocarbon, transmittance, initial and final pH, zeta potential and resident time are affected in two pretreatment reactors. Results show, the minimum amount of turbidity of 4.5 NTU is obtained in the best conditions.
