Repla­cing lar­ge amounts of pro­cess water is cost-inten­si­ve and was­tes valuable resour­ces. In a salt­wa­ter aquacul­tu­re, the aim is the­r­e­fo­re to achie­ve the lowest pos­si­ble water exch­an­ge. The SEAWATER cir­cuit con­sists of various mecha­ni­cal fil­ter units as well as our paten­ted bio­fil­ters. The­se remo­ve com­ple­te­ly all feed resi­dues and ani­mal excre­ments from the tank. The ani­mals can grow up in clear water under opti­mal con­di­ti­ons and wit­hout stress. This enables the best pro­duct qua­li­ty. The spe­cial thing about our tech­no­lo­gy is that we com­bi­ne natu­ral and engi­nee­ring sci­en­ces. All com­pon­ents in the sys­tem are pre­cis­e­ly desi­gned for each other in terms of pro­cess tech­no­lo­gy and respect the strict requi­re­ments that the ani­mals place on water treatment.

drBB gelös­ten  Der SEAWATER Cube umfasst neben dem Pro­duk­ti­ons­be­cken meh­re­re phy­si­ka­li­sche und bio­lo­gi­sche Fil­ter­stu­fen, wel­che alle par­ti­ku­lä­ren und gelös­ten Rest­stof­fe aus dem Pro­zess­was­ser rück­stands­los entfernen.


We com­bi­ne seve­ral mecha­ni­cal and bio­lo­gi­cal fil­ters in our cir­cuit. Every drop of water in the basin goes through all fil­ters three times an hour.

Water exchange

By com­bi­ning mecha­ni­cal and bio­lo­gi­cal fil­ter units, 99% of the water in the Cube is clea­ned – so the­re is only a con­sump­ti­on of 500 liters per day.

Circular flow

Using powerful pumps and air­lifts, we gene­ra­te a cir­cu­lar flow in the sys­tem, which pro­vi­des the fish with ide­al con­di­ti­ons to deve­lop their natu­ral swarm­ing behavior.

Salt water

The basis for the SEAWATER is nor­mal tap water. This is sal­ted with a spe­cial mine­ral mix­tu­re that is simi­li­ar to natu­ral water from the sea.


The SEAWATER Cube as a recir­cu­la­ting aquacul­tu­re sys­tem is cha­rac­te­ri­zed by its loca­ti­on inde­pen­dence. The sys­tem runs far away from natu­ral waters and the­r­e­fo­re has no inter­ac­tions with the envi­ron­ment. Nega­ti­ve influen­ces on the seas, for exam­p­le by net cages from fish drop­pings, feed exces­ses and ani­mal car­cas­ses, are com­ple­te­ly avo­ided. In addi­ti­on, meteo­ro­lo­gi­cal events (e.g. El Niño) or indus­tri­al pol­lu­ti­on (micro­pla­s­tics, hea­vy oil, hea­vy metals) do not thre­at the ani­mals. Recir­cu­la­ting sys­tems enable con­trol­led rea­ring and crea­te trans­pa­ren­cy with regard to the ori­gin and the ingre­di­ents of fish products.




The switch cabi­net is the heart of our sys­tem. The pro­gramma­ble logic con­trol­ler („PLC“ for short) is instal­led here, in which the spe­ci­es-spe­ci­fic fish know­ledge is stored. In addi­ti­on, the data from all actua­tors, sen­sors and sub­sys­tems run tog­e­ther in the PLC. Various func­tions are pro­grammed into the soft­ware. Thus, the soft­ware con­trols all pro­ces­ses in the sys­tem ful­ly auto­ma­ti­cal­ly within spe­ci­fied value ran­ges. This redu­ces the workload for the ope­ra­tor and increa­ses pro­duc­tion relia­bi­li­ty signi­fi­cant­ly. The auto­ma­ti­on also saves all recor­ded data in the cloud. This is used for regu­lar ana­ly­sis and opti­miza­ti­on of the pro­duc­tion processes.


Water Qua­li­ty


Deni­tri­fi­ca­ti­on as water fil­tra­ti­on in the absence of oxy­gen remo­ves toxic nitro­gen com­pounds from a par­ti­al­ly clo­sed or clo­sed aquacul­tu­re plant. During this pro­cess, nitra­te (NO3) is bro­ken down from the water in the sys­tem with the help of spe­cial bac­te­ria. The deni­tri­fi­ca­ti­on pro­cess has the fol­lo­wing advan­ta­ges: Sin­ce no toxic nitra­te accu­mu­la­tes in the basin, the water chan­ge rate and thus water con­sump­ti­on can be redu­ced to 1% per day. In addi­ti­on, the fish grow up in an unpol­lu­ted envi­ron­ment and ani­mal wel­fa­re is per­ma­nent­ly gua­ran­teed. The ful­ly auto­ma­ted SEAWATER deni­tri­fi­ca­ti­on redu­ces the dai­ly workload in the plant.
