If I had to guess, I would say that "triple bleaching" refers to successive applications of oxalic acid, sodium hypochlorite (chlorine bleach), and a peroxide bleach. This isn't something that you're going to want to try with a floor that has already been laid.

Hockthebourgeois is correct, it can greatly affect the durability of the wood. You are almost certain to damage your floors if you attempt this yourself. Please, please don't do this to 90 year old wood floors.

If installing new and you want light colored wood floors go with maple, birch, or ash. Let oak look like oak.
