1. Throw it & use new fluid

2. Purify & reuse

I am by no means an expert in this area. I speak only from experience with compressor fluids. 

I imagine that it depends on what it is contaminated with.  Solids can generally be removed, though not completely.  Analysis of the solids removed often can give information on wear of the system. Water is much harder to get out.  If it has been degraded by heat, it is much less likely that it can be used for the same purpose.

But the fluid will have specifications that must be met. Where there are many turbines, it may be economically viable to gather used fluids from many systems and treat it in bulk, instead of one turbine at a time, and reuse. But it would have to piloted to determine if it provides any advantage to just changing it out with new fluid.
