How about a resin exchange column? You could schedule your tank dump/treatment when the silver drops to the ppm range.

You can use successfully Electro-Catalytic Precipitation by oxidative process, where the metals in solution, no matter what metal salt it is, goes in solid oxides and then will be mechanically filtered and recovered by metallurgical technologies.
