Slow distillation will be my answer then. I'll just set up a still as part of 
the system to purify part of the water each day.
What to do with the salts that result, I don't know. Maybe they can be melted 
down in the furnace to reclaim the metal?

I don't intend on going anywhere near those figures! At least not anywhere in 
the near future! Maybe if I get rich and start a real utility, but for my own 
stuff, it's just not needed or practical. I'd have to use to much expensive 
equipment to handle such temps and pressures in my boiler. While the furnace 
will handle much higher temps in order to melt metals, the boiler won't use a 
fifth of the furnace's output, I hope. This will allow me to use the rest of 
the furnace's power for other purposes.
I don't think Jack Daniels and Johnny Walker are relatives, but they both are 
in the same business!  ;-)
