Hot Climate RAS Project Story
Client Challenge
A commercial aquaculture project in the Middle East faced extreme ambient heat, high evaporation rates, and limited freshwater availability. Traditional flow-through or pond systems could not meet biosecurity and water efficiency targets.
Recommended System Logic
TurnkeyRAS delivered a chilled RAS concept with optimized insulation strategy, evaporation recovery planning, redundant oxygenation, and climate-specific automation alarms. Mechanical filtration and biofiltration were sized for peak summer loading.
Key Modules
Mechanical Filtration
High-capacity drum and micro-screen filtration for reliable solids removal in commercial RAS loops.
Biofiltration
Moving bed and fixed film biofilters engineered for ammonia and nitrite control under commercial feed loading.
Oxygenation
High-efficiency oxygen cones, diffusers, and injection systems for commercial stocking densities.
Degassing
CO2 stripping columns and degassing loops to maintain safe carbon dioxide levels in intensive culture.
Automation & Monitoring
PLC/SCADA panels, sensor networks, and alarm logic for reliable commercial RAS operation.
Engineering Notes
- •Thermal load modeling included building envelope and tank surface area
- •Redundant oxygen supply specified for summer peak biomass
- •Automation included high-temperature and low-DO escalation alarms
Outcome / Expected Value
- •Stable water quality targets maintained under summer peak loads
- •Reduced freshwater makeup vs. semi-open alternatives
- •Predictable batch management with integrated monitoring
