As to your question on typical removal for a setup, I would it depends largely with respect to your bio-load and what is the reasonable level of nitrate you would want it to be.
3. Deniball is not a must. It is just convenient and provides constant supply of carbon source.

If I have a tank that is 1000litre of water, that produces 2g of nitrate per day. What type/design of denitrator is needed to bring the nitrate to 0? Which mean I need a denitrator to reduce 20ppm of nitrate in 1000litre of water in 1 day.
