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 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
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
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
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 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
„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.
