Protein skimmers in recirculation systems

Protein skimmers in recirculation systems

Effec­ti­ve water tre­at­ment in aquacul­tu­re can­not be done without the work of bac­te­ria, becau­se in spe­cial­ly built bio­fil­ters they often con­vert toxic excre­ments of the fish into ani­mal and envi­ron­ment­al­ly friend­ly sub­s­tan­ces. Howe­ver, if bac­te­ria are pre­sent in lar­ger num­bers in the bea­ring tank, they can cau­se unde­s­i­ra­ble side effects. The­re­fo­re, in clo­sed recir­cu­la­ti­on sys­tems, a pro­te­in skim­mer is used in addi­ti­on to bio­lo­gi­cal filters.

Microplastics

Microplastics

Micro­plastics are ever­y­whe­re – in the sea, in the air, in cos­me­tic pro­ducts. The small plastic par­ti­cles have beco­me an inte­gral part of our envi­ron­ment. Accord­ing to sci­en­tists and rese­ar­chers, the­re are vir­tual­ly no more plastic-free are­as on earth. Micro­plastics are ubi­qui­tous, espe­cial­ly in the food sec­tor. Pack­a­ging and plastic bags often end up across the rivers in the oce­ans, whe­re they are con­su­med by fish and other mari­ne ani­mals as sup­po­sed food. Ulti­mate­ly, micro­plastics have also beco­me part of our diet. In the new blog post we shed light on the topic of micro­plastics and its effects in detail and give hel­pful tips for easy reduction.

Urban Farming as the most environmentally friendly method of food production

Urban Farming as the most environmentally friendly method of food production

Living in the city and at the same time shop­ping for regio­nal, fresh pro­ducts wit­hin wal­king distance: That sounds like an ide­al that would have a las­ting posi­ti­ve effect on our envi­ron­ment. This type of food sup­ply is still lar­ge­ly a long way off, but the­re are alrea­dy some exci­ting and rea­listic con­cepts. „Urban far­ming“ is the gene­ric term for the pri­ma­ry food pro­duc­tion in urban are­as or the neigh­bo­ring regi­on, in simp­le terms it means agri­cul­tu­re in the city. In the new blog post, we high­ligh­ted both chal­len­ges and oppor­tu­nities for the imple­men­ta­ti­on of spe­ci­fic urban far­ming projects.

First step in water treatment: The drum filter

First step in water treatment: The drum filter

Almost ever­yo­ne has done this at least once in their own four walls: For examp­le, you use a sie­ve and water and sim­ply rin­se the dirt away, lea­ving only the clean salad at the end. This is a type of mecha­ni­cal clea­ning that almost ever­yo­ne uses regu­lar­ly. In order to achie­ve a simi­lar effect in a recir­cu­la­ting aquacul­tu­re sys­tem (RAS), a com­pa­ra­ble fil­ter opti­on is used in a figu­ra­ti­ve sen­se: the drum fil­ter, a cylind­ri­cal drum cove­r­ed with a fine-mesh fil­ter net. Learn more about this smart fil­ter tech­no­lo­gy in our blog post!

Automation of fish farming systems

Automation of fish farming systems

The topic of auto­ma­ti­on is beco­m­ing more and more important, espe­cial­ly in today’s world. Espe­cial­ly in indus­try, whe­re high pro­duc­ti­vi­ty is always the goal and pro­ces­ses are incre­a­singly digi­ta­li­zed (Indus­try 4.0), many dif­fe­rent app­li­ca­ti­ons of auto­ma­ti­on can be found. In our blog­post we exp­lain in detail, how pro­gramm­a­ble logic con­trol­lers can be used in recir­cu­la­ti­on sys­tems and how pro­ces­ses and workload can be optimized.

Sedimentation in detail

Sedimentation in detail

Sedi­men­ta­ti­on is part of the water fil­tra­ti­on in our cir­cu­la­ti­on sys­tem. But what exact­ly is it respon­si­ble for and how does it work? In the blog post we go into more detail about the com­po­nent and exp­lain how water loss in recir­cu­la­ti­on sys­tems can be mini­mi­zed through smart recovery.

Fish farming on land versus fish farming in the sea

Fish farming on land versus fish farming in the sea

„Why are fish so indif­fe­rent to us?“ – This is the ques­ti­on asked by repor­ter Han­nes Jae­ni­cke in the ZDF docu­men­ta­ry “Im Ein­satz für den Lachs”. The docu­men­ta­ti­on shows the fatal con­se­quen­ces of fac­to­ry far­ming in so-cal­­led sal­mon farms in net cages for the natu­ral wild sal­mon stocks and the eco­sys­tem. In our blog post we show that aquacul­tu­re also works in an envi­ron­ment­al­ly friend­ly way.
