Not sure what exact device you are asking about. There are sulfur and carbon based denitrators to reduce nitrate. They work, but so do many other methods.

I review nitrate reduction methods here:

Might be talking about Natureef system that uses methanol to grow bacteria to "clean" your water. Some claim that they hardly ever do water changes.

Some people like them quite a lot, but they are not very popular relative to other methods, like organic carbon dosing.

I discuss them in the article.
