Estimating biofilter size for RAS systems
We can use this equation to calculate the volume of media a trickling filter would need as: 2,300 g TAN/day ÷ 90 g TAN removed/m 3 /day = 25 m 3. If this trickling filter were sized at 2.5 m square, the media height would be 4.0 m. In trickling filter design, there is space both above and below the biofilter media.
