Paper: OIL FIELD WATER RECYCLING

Flow back and produced waters in the oil field are heavily laden with contaminates including insoluble iron sulfides,
poisonous hydrogen sulfide, residual gels, friction reducers, and other chemicals. In this paper we will look at chlorine dioxide (ClO2) as one possible solution to these problems. As a powerful, yet selective oxidizer, ClO2 has the ability to break up the residual gels and friction reducers while removing the insoluble iron sulfide and killing the hydrogen sulfide. As an additional plus, ClO2 is an EPA approved biocide that kills the bacteria which are the root cause of many of the problems with water reuse.
