Dosing carbohydrates produces protein, biomass. A part of this protein will be removed by a skimmer ( max +- 30%,
http://www.baharini.eu/baharini/doku...iwitafschuimer ) most of it will be consumed by other organisms and become part of the food chain. Consumption is formation of biomass and ammonia. This ammonia will be nitrified to nitrate. Nitrification does consume alkalinity. To remove the nitrate produced carbohydrates must be dosed. A cycle is introduced from NO3 to NO3 , this cycle includes nitrification consuming alk.
At a high C:N ratio ( biopellets reactor?) no nitrate is formed as ammonia will be assimilated to produce protein. The assimilation of ammonia NH4 consumes alkalinity but only +- half of alk consumption if the same amount of ammonia was nitrified. At the downsite the very high biomass production which is +- 40 x the amount produced during nitrification of the same amount of ammonia. The cycle introduced this way is from NH4 to NH4. including the formation of a lot of biomass.
What to do with the produced biomass?
Carbon dosing is common practice in aquaculture systems. In these systems the biomass will be harvested after a period of time.
