Abstract
The existing research, demonstration, and commercial recirculating aquaculture systems almost exclusively use fixed film biofilters for nitrification. The main advantage of this type of process is that the biofilm can maintain a relatively long cell detention time that accommodates the low growth rate of nitrifying bacteria. Due to the nature of the diffusion controlled process that occurs in a biofilter, the nitrification rate of a fixed film filter is directly related to ammonia concentration in the system. Based on biofilm theory, this paper presents a mathematical model for ammonia removal in a recirculating system, considering mass transfer through a biofilm, feeding rate, and volume and water exchange rates of the system.
