System Overview
The Recirculating Aquaculture System (RAS) is an industrial aquaculture model that enables water recycling through advanced water treatment technologies including physical filtration, biological filtration, oxygenation, and disinfection. This closed-loop system simulates natural ecosystem processes, converting organic waste into harmless substances while maintaining stable water quality for optimal aquatic growth conditions.
System Components
- Physical Filtration Unit: Removes solid particles like uneaten feed and feces using microstrainers or sand filters with precision up to tens of micrometers.
- Biological Filtration Unit: Utilizes microorganisms on ceramic rings or biochemical balls to convert harmful ammonia nitrogen into nitrate.
- Oxygenation Unit: Employs microporous aerators or pure oxygen aeration devices to maintain optimal dissolved oxygen levels.
- Disinfection Unit: Uses UV or ozone technology to eliminate pathogens without harmful residues.
System Advantages
Efficient Resource Utilization
Achieves 90-99% water recycling rates and enables high-density aquaculture with yields up to dozens of kilograms per square meter, optimizing both water and land use.
Precision Environmental Control
Maintains stable water parameters (temperature, pH, dissolved oxygen) and allows customized light/temperature settings for species-specific requirements (e.g., 10-18°C for rainbow trout).
Superior Product Quality
Ensures uniform growth and high safety standards by minimizing disease exposure and harmful substance accumulation in aquatic products.
Environmental Sustainability
Dramatically reduces wastewater discharge and prevents ecological interference compared to traditional open aquaculture methods.
Applications
Urban Aquaculture
Ideal for space-constrained environments like warehouses or building basements, enabling fresh seafood production near restaurants and markets.
High-Value Species Cultivation
Perfect for grouper (22-28°C), rainbow trout, and prawns with precise control of salinity (25-35‰) and other critical parameters.
Seedling Breeding
Enhances Litopenaeus vannamei seedling survival with stable 28-32°C water temperatures and minimal ammonia nitrogen levels.
Research & Education
Provides controlled environments for studying growth hormones and aquaculture principles, with precise data recording capabilities.
