Also any water distillation will not remove some volital organics.
On the other hand, there are several types of deionized water
processes. Reverse osmoses being one. However, as usual, a varriety of
filter membrains are availiable depending on the cost. The reverse
osmosis membrains designed for sea water desalination result in the
purest water availiable. SCHRAMMR@WLSVAX.WVNET.EDU (even rain water has alot of junk in it.) The
less expensive reverse osmosis units commonly purchased for the home, or
for ground water filtering, or in machines at stores do not have as fine
of a membrane letting more stuff stay in the water.
So, what will work for photographic processes ? Try and see what
works. But, do not discount "deionized", because it can work or not
depending on its quality.
