Aquaponic Sludge Mineralisation & Desalination Loop – EAS2017

Two weeks ago, we have attended the Aquaculture Europe 2017 conference in Dubrovnik. I (Boris) presented our latest findings with respect to sludge mineralisation in aquaponic systems. It is a challenge to treat fish sludge within aquaponic systems to reduce the quantity of waste. Even more important is the objective to recover the valuable nutrients that are trapped in the sludge. Nutrient recovery by sludge mineralisation constitutes a great opportunity to complement the hydroponic nutrient solution in a sustainable manner.  Read more

COST Aquaponics Conference and further Plans

Yes – we are still alive, and no – we did not forget about posting on Developonics. We are currently just busy with publishing our research as well as already planing new aquaponics related projects. What else have we done? In March, Simon has been presenting the model on decoupled aquaponic systems that he developed at the COST Aquaponics Conference “Research Matters”. Unlike in one-loop recirculating aquaponics systems, decoupled two- or three-loop systems (i.e. comprising of a RAS & hydroponic system, or RAS, hydroponic, and remineralization system respectively) follow the principle of a one-way nutrient flow. This makes it possible to ensure optimal conditions for both fish and plants; i.e. the fish are held in optimal RAS conditions, and the hydroponic water can be supplemented with macro- and micronutrients to ensure an optimal nutrient solution.
