Here in the Netherlands several methods exist.
There's an expensive technic with a kind of gas chamber etc where books in
batches are deacified.
That is used by archives to preserve the enormous amount of books with bad
paper of the last 250 years
with Alum sizing etc.
Another disaster are some of the writing inks with an iron in it. The
chemistry changes and the paper next to the writing is completely destroyed,
no remedy for it I believe.
