Denitrification is a process to remove nitrates not create them. In this case bio-balls are used in a low flow and low oxygen environment which can in theory reduce nitrates provided the conditions are right.

Nitrification is the process which creates nitrate from ammonia. In this case bio-balls are used in a higher flow with high oxygen environment such as a wet-dry system. This is the type of system to avoid as it's too efficient at creating nitrates and can end up creating a build up of nitrates which is hard to deal with in typical salt setups.
