An important part of our activity is research on decoupled aquaponics systems. They make it possible to cultivate fish and plants under optimal conditions and to process the water in further stages.
With regard to aquaponics research, we were able to follow the emergence of an interesting scientific work that deals for the first time with the system design of a decoupled aquaponic facility (DAPS).
„Navigating towards Decoupled Aquaponic Systems: A System Dynamics Design Approach“deals with the question of what a possible system design of a decoupled aquaponic facility could look like.
Decoupled aquaponic facilities are characterized by the fact that they are operated with 2 or more decoupled circuits. In addition, there is the anaerobic stage via UASB / EGSB bioreactors, which was also included in the proposal for the plant design. This design has several advantages:
- The individual circuits create the optimal conditions for each culture
- Better adaptation of the water parameters to the different fish and plant cultures
- Anaerobic stage in the nutrient treatment via UASB / EGSB, for additional mineralization of the process water
- Concentration of the nutrients in the water to achieve a high nutrient density
- It is possible to supplement the aquaponic solution with additional plant nutrients
The work is available here free of charge and in full.
