Abstract

Abstract:

This paper suggests a new method of treating sewage in oil production, discusses several factors influencing dissolved—gas flotation. Experiments show that dissolved—gas flotatin gs a better method for treating sewage than coagulation. This treatment can decrease the amount of oil, SS and increase MF significantly, Further treatment by filtration gives clear water with MF>20,SS<3.4 mg/l, oil<3.0 mg/l. So the treated water can be reinjected into the formation and it causes less permeability decrease than that treated by the present method.

Key words: Sewage treatment, Dissolved-gasflotation, Filtration, Formation damage
