So 2% is lost how often? Every day? Every week? Every month? I don't understand what 98% reclaimed means.

To quote the article that this post links to:

“Let’s say you collect 100 pounds of water on the station. You lose two pounds of that and the other 98 percent just keeps going around and around. Keeping that running is a pretty awesome achievement.”

This means that for any sample of liquid waste, 98% of that quantity will be converted back into water, while the remaining 2% will be discarded.

This does not answer the question. You lose two pounds of it, sure. How do you lose them?
