Closed-Loop Blue Bioeconomy & Advanced Water Treatment
Theme 3 addresses the vital environmental imperative of sustainable, resource-efficient, and zero-waste aquaculture production. With escalating freshwater scarcity and strict environmental discharge regulations, closed-loop technologies like Recirculating Aquaculture Systems (RAS), moving bed biofilm reactors (MBBR), and integrated aquaponics are essential to modern food security.
This session welcomes interdisciplinary research on cutting-edge nitrification/denitrification biofiltration, solid-liquid separation, advanced oxidation processes (AOPs), microalgal wastewater bioremediation, and valorization of fish fecal sludge into biogas, biochar, and organic soil amendments.
Key Topic Areas for Submission
Next-Gen RAS Engineering
Hydrodynamic design of culture tanks, energy-efficient degassing, oxygenation systems, ozone disinfection, and low-footprint RAS architectures.
Advanced Biofiltration & Microbial Dynamics
Nitrifying moving bed biofilm reactors (MBBR), fixed-bed biofilters, microbial community ecology, and anaerobic ammonium oxidation (anammox) systems.
Effluent Treatment & Water Reuse
Membrane bioreactors (MBR), electro-coagulation, microfiltration, constructed wetlands, and UV advanced oxidation for total water recycling.
Integrated Aquaponics & IMTA
Decoupled aquaponics systems, nutrient stoichiometry balance, hydroponic crop optimization, and Integrated Multi-Trophic Aquaculture (IMTA).
Sludge Valorization & Nutrient Extraction
Dewatering, anaerobic digestion of aquatic solid waste for biogas generation, phosphorus recovery, and conversion of fish sludge to biofertilizers.
Circular Blue Bioeconomy Models
Life Cycle Assessment (LCA) of aquaculture systems, carbon footprint accounting, energy efficiency optimization, and circular industrial symbiosis.
