Marine recirculating aquaculture systems need to move water, capture solids, support nitrification, add oxygen, and strip carbon dioxide. Pairing a low-head PolyGeyser bead filter with an airlift pump can combine those jobs into a compact, low-water-loss treatment...
In low-TAN marine hatchery, broodstock, and fingerling systems, peak biofilter capacity is not always the most important design question. A simple linear model, calibrated only in the low-ammonia range, can be a more stable and practical way to estimate ammonia...
Floating bead filters can simplify recirculating aquaculture system design by combining two jobs – solids clarification and biological nitrification – in one expandable granular media filter. Estimated read time: 10 minutes | Audience: aquaculture...
