We supply facilities equipped with flowthrough, hybrid and RAS technologies. Our advice on the best technical solution in each case is therefore entirely impartial. Often, the best solution will be a combination of several technologies – based on the available water resources.
Our flexible solution with full water flowthrough. For facilities with stable access to raw water of a suitable temperature. Artec Aqua Flowthrough System™ provides the best cost/benefit performance at sites that enjoy favourable and stable conditions, and where the temperature of the raw water does not fall below 8°C in winter.
Flowthrough technology has been fundamental for the onshore aquaculture industry since its inception. Artec Aqua Flowthrough System™ replicates most closely the biological conditions found in nature, and is the most biosecure system. The facilities operate equally well with fresh water or seawater.
The best of both worlds. Recirculation of up to 65% of the water volume. For hatcheries with sufficient access to fresh water, as well as for post-smolt and ongrowing facilities without access to raw water of a suitable temperature, and where controlled water temperature is desired. An Artec Aqua Hybrid System™ is the most cost-effective solution where the raw water needs to be heated.
From a technical point of view, an Artec Aqua Hybrid System™ is much the same as an Artec Aqua Flowthrough System™. The only difference is the CO2 aerator.
The main component in an Artec Aqua Hybrid System™ is the DeGasso CO2 device that we have developed ourselves.
RAS with optimal water quality. For facilities where the available water volume is limited or where emission requirements preclude the use of other technologies.
The tank farm in an Artec Aqua RAS™ facility is almost identical to that of a flowthrough or hybrid system. Only the facilities’ technical rooms differ materially from each other.
The heart of the RAS module is the biofilter. We have developed our own Multistep MB biofilter, which is based on a moving-bed reactor for effective conversion of ammonia.
