Diffusers send oxygen into the tank to promote continuous microorganism growth, and a mesh sieve in the tank helps keep the media carriers from flowing away with the wastewater. MBBR media carriers have a density similar to that of water, so they mix well with the wastewater to promote consistent waste digestion.
The medium is used in the reactor to provide aeration and agitation. This mechanical movement of the media is the key to its superior nitrification ability (breakdown of ammonia into nitrite and then eventually nitrate). As the media moves through the reactor, it hits the reactor walls and other media, shedding excess biofilm and keeping the media clean so the nitrifying bacteria can work at peak efficiency. Since the ceramic doesn't move, the biofilm covering the media becomes clogged with "sludge," which is dead nitrifying bacteria and fish waste. In addition, the water in the tank does not flow easily through the ceramic media, so the efficiency is much lower than that of MBBR media
