based on what you mentioned, i think its based on ur first hypothesis, you are saying that this denitrator can almost do away the 30% water change, but this is on assumption that no more new nitrates form, but in real life, the tank is constantly producing ammonia, nitrites and nitrates in the process, i feel that for a denitrator to work successfully, the rate of removal has to be faster than the rate of formation. |

Brother you are correct for the initial portion of development of bacteria colonies. however i think all of us meant that the denitrator's digesters will adjust itself with the bioload produced. The initial feeding was to help kick start the denitrator. without sufficient feed, excess bacteria will starve and die off. hence removal rate will equal rate of formation unless you feed denitrator with cultures once in a while which is good as you will ensure that bb are there with the law of competitive inhibition.

So you are saying that there will never be a scenario whereby formation rate exceeds removal rate? even with limitations like denitrator volume/size?

But like any engineering math there is always a constant of removing nitrate which can be derived from other equation by another equation. But i think the total surface area will equate to the max BB. Number of BB relates to removal rate. The BB count also must depend on the survial rate of the BB in a given time and feed. time n feed relate to amount of nitrate produced by the tank population which realtes to the amount of water and population in the tank. Hope that i didnt confused any1. kekek |

I pretty much figured out how to make the denitrator but how do I connect it to an overhead filter?
If the denitrator outlet could somehow be connected to the pump suction , the output can be filtered before entering the tank. The denitrator inlet connected at filter outlet, with the excess water overflowing into the tank. This way the clogging of the denitrator can be reduced significantly. Can anyone figure out how? |
