The goal was to assess the concentrations of these parameters after four days and compare them with relevant literature examples in the aquaculture industry and in source-separated urine research. Four day experiments were conducted which tested the evolution in concentration of Total Ammonia Nitrogen (NH4 + /NH3), Nitrite (NO2 - ), Nitrate (NO3 - ), Phosphate (PO4 3- ), and Dissolved Oxygen (O2) after an initial nutrient input. The design, building and monitoring of System 1, System 2 and System 3 was documented and described in detail. A case study was conducted in a farm in Askeröd, Sweden, which involved building two aquaponic systems (System 1 and System 2) and a human urine-based aquaponic system (System 3), with different degrees of component complexity and sizes. An overview of the different types of aquaponic systems and current research on the field is also presented. Research on aquaculture wastewater and human urine wastewater is reviewed and its potential application with aquaponic systems is studied. In this thesis the concept of aquaponics and the underlying processes are explained. Aquaponics is a food production system which combines fish farming (aquaculture) with soilless crop farming (hydroponics). The main objective of this thesis is to study the developing fields of aquaponics and its potential for aquaculture wastewater treatment and human urine treatment.
