SEAWATER CIRCUIT
ReplaÂcing larÂge amounts of proÂcess water is cost-intenÂsiÂve and wasÂtes valuable resourÂces. In a saltÂwaÂter aquaculÂtuÂre, the aim is theÂrÂeÂfoÂre to achieÂve the lowest posÂsiÂble water exchÂanÂge. The SEAWATER cirÂcuit conÂsists of various mechaÂniÂcal filÂter units as well as our patenÂted bioÂfilÂters. TheÂse remoÂve comÂpleÂteÂly all feed resiÂdues and aniÂmal excreÂments from the tank. The aniÂmals can grow up in clear water under optiÂmal conÂdiÂtiÂons and witÂhout stress. This enables the best proÂduct quaÂliÂty. The speÂcial thing about our techÂnoÂloÂgy is that we comÂbiÂne natuÂral and engiÂneeÂring sciÂenÂces. All comÂponÂents in the sysÂtem are preÂcisÂeÂly desiÂgned for each other in terms of proÂcess techÂnoÂloÂgy and respect the strict requiÂreÂments that the aniÂmals place on water treatment.
Filters
We comÂbiÂne seveÂral mechaÂniÂcal and bioÂloÂgiÂcal filÂters in our cirÂcuit. Every drop of water in the basin goes through all filÂters three times an hour.
Water exchange
By comÂbiÂning mechaÂniÂcal and bioÂloÂgiÂcal filÂter units, 99% of the water in the Cube is cleaÂned – so theÂre is only a conÂsumpÂtiÂon of 500 liters per day.
Circular flow
Using powerful pumps and airÂlifts, we geneÂraÂte a cirÂcuÂlar flow in the sysÂtem, which proÂviÂdes the fish with ideÂal conÂdiÂtiÂons to deveÂlop their natuÂral swarmÂing behavior.
Salt water
The basis for the SEAWATER is norÂmal tap water. This is salÂted with a speÂcial mineÂral mixÂtuÂre that is simiÂliÂar to natuÂral water from the sea.
SEA FISH FAR AWAY FROM THE SEA
The SEAWATER Cube as a recirÂcuÂlaÂting aquaculÂtuÂre sysÂtem is chaÂracÂteÂriÂzed by its locaÂtiÂon indeÂpenÂdence. The sysÂtem runs far away from natuÂral waters and theÂrÂeÂfoÂre has no interÂacÂtions with the enviÂronÂment. NegaÂtiÂve influenÂces on the seas, for examÂpÂle by net cages from fish dropÂpings, feed excesÂses and aniÂmal carÂcasÂses, are comÂpleÂteÂly avoÂided. In addiÂtiÂon, meteoÂroÂloÂgiÂcal events (e.g. El Niño) or indusÂtriÂal polÂluÂtiÂon (microÂplaÂsÂtics, heaÂvy oil, heaÂvy metals) do not threÂat the aniÂmals. RecirÂcuÂlaÂting sysÂtems enable conÂtrolÂled reaÂring and creaÂte transÂpaÂrenÂcy with regard to the oriÂgin and the ingreÂdiÂents of fish products.
INTELLIGENT SELF-REGULATION
The switch cabiÂnet is the heart of our sysÂtem. The proÂgrammaÂble logic conÂtrolÂler („PLC“ for short) is instalÂled here, in which the speÂciÂes-speÂciÂfic fish knowÂledge is stored. In addiÂtiÂon, the data from all actuaÂtors, senÂsors and subÂsysÂtems run togÂeÂther in the PLC. Various funcÂtions are proÂgrammed into the softÂware. Thus, the softÂware conÂtrols all proÂcesÂses in the sysÂtem fulÂly autoÂmaÂtiÂcalÂly within speÂciÂfied value ranÂges. This reduÂces the workload for the opeÂraÂtor and increaÂses proÂducÂtion reliaÂbiÂliÂty signiÂfiÂcantÂly. The autoÂmaÂtiÂon also saves all recorÂded data in the cloud. This is used for reguÂlar anaÂlyÂsis and optiÂmizaÂtiÂon of the proÂducÂtion processes.
DENITRIFICATION AS WATER FILTRATION
DeniÂtriÂfiÂcaÂtiÂon as water filÂtraÂtiÂon in the absence of oxyÂgen remoÂves toxic nitroÂgen comÂpounds from a parÂtiÂalÂly cloÂsed or cloÂsed aquaculÂtuÂre plant. During this proÂcess, nitraÂte (NO3) is broÂken down from the water in the sysÂtem with the help of speÂcial bacÂteÂria. The deniÂtriÂfiÂcaÂtiÂon proÂcess has the folÂloÂwing advanÂtaÂges: SinÂce no toxic nitraÂte accuÂmuÂlaÂtes in the basin, the water chanÂge rate and thus water conÂsumpÂtiÂon can be reduÂced to 1% per day. In addiÂtiÂon, the fish grow up in an unpolÂluÂted enviÂronÂment and aniÂmal welÂfaÂre is perÂmaÂnentÂly guaÂranÂteed. The fulÂly autoÂmaÂted SEAWATER deniÂtriÂfiÂcaÂtiÂon reduÂces the daiÂly workload in the plant.
