Ammonia and nitrite are toxic to fish, but nitrate is relatively harmless and is the preferred form of nitrogen forRecirculating Aquaculture Tank Production SystemsRecirculating aquaculture produc-tion systems may offer an alterna-tive to pond aquaculture technolo-gy. Through water treatment and reuse, recirculating systems use a fraction of the water required by ponds to produce similar yields. Because recirculating systems usu-ally use tanks for aquaculture pro-duction, substantially less land is required.

Recirculating Aquaculture Tank Production Systems

Water treatment components must be designed to eliminate the adverse effects of these waste products. In recirculating tank systems, proper water quality is maintained by pumping tank water through special filtration and aeration or oxygenation equipment. Each component must be designed to work in conjunc-tion with other components of the system.Recirculating Aquaculture Technologies SpringerLinkIn aquaculture, different solutions have been designed to maximize water use including highly intensive recirculating systems that incorporate water filtration systems such as drum filters, biological filters, protein skimmers and oxygen injection systems (Hulata and Simon 2011). Despite a strong conviction by pioneers in the industry about the Aquaculture Recirculating Water Treatment Sand Filter Tank Recirculating Sand Filters (RSF) Barnstable County Aquaculture Recirculating Water Treatment Sand Filter Tank Reduction in Biological Oxygen Demand (BOD) consistently exceeds 90% after treatment by the sand filter, and ranges from 97-98% efficiency when the water temperatures exceed 10 C (Figure 11). Septic tank BODs ranged from 151-344 mg/l with an average of 223 mg/l. Treatment through the sand filter reduced this to 2.3-18.0 mg/l and averaged 8.8 mg/l.

Due to the slow flow rate, a thin slimy layer of biomass forms on top of the sand. This layer contributes to the purification of the water, acting as a bio-filter (see 8.4.3), but when it becomes too thick it is mechanically removed to restore Aquaculture Recirculating Water Treatment Sand Filter Tank
