Produced water from polymer flooding(polymer produced water) was difficult to be treated by conventional two-stage settling process. A new type of double-cone air sparged hydrocyclone (DcASH) was designed to treat produced water from polymer flooding. The experimental results showed that DcASH had a high capacity, and it was a very promising device for treatment of produced water from polymer flooding.
