One sorta "reuse" mode is to use rinse water from one process step in a prior
step.

To give a specific example, when a clean line has two cleaners, say an
alkaline first step, and an acid or microetch second step, it is easy to take
the rinse waters from the final step, and pumping them back for reuse in the
rinses between the alkaline clean and acid clean.

This is a pretty easy step, and you do not have to sweat the quality of the
water.
