Narrative:

During arrival into atl (koltt 1) we were given a 'descend via' clearance and cleared for the va runway 9R. We were also following an md-80. The distance (based on TCAS) between us was between 3-3.5 miles. We had been following this aircraft from some point in the arrival and through the turns to base leg and final.on several occasions we encountered mild wake turbulence which I was able to avoid by utilizing the MCP mode of automation. Prior to turning final we encountered a significant wake (about 10-20 degrees of left bank). At this point I went to manual flying which resulted in a slight delay of my turn to final. We were shortly thereafter given a 070 degrees vector to rejoin the localizer. I flew slightly high on final once electronic and visual guidance was available. The remainder of the flight was uneventful.
