RAS Equipment
RAS equipment packages for commercial fish farms, hatcheries and intensive aquaculture facilities.
Complete Components of a Commercial Recirculating Aquaculture System
A commercial RAS is an integrated water treatment system designed to maintain stable water quality through continuous water circulation and treatment.
Unlike traditional aquaculture systems, RAS requires multiple equipment modules to manage. Each component performs a specific treatment function while working together as one complete recirculating aquaculture system.
A successful recirculating aquaculture system requires more than individual equipment. It requires a complete combination of culture systems, filtration, biological treatment, gas management, oxygen control, and disinfection technologies working together.
From equipment selection and customization to manufacturing and project support, YUTANK works with customers on RAS systems configured around species, production targets and site conditions.
Seven core equipment modules — configured to your species, biomass and water-quality targets, engineered and built in-house by YUTANK.
Culture Environment
Culture Environment for Intensive Fish Production
Aquaculture tanks provide the controlled environment where fish are raised within a recirculating aquaculture system. YUTANK designs and supplies aquaculture tanks suitable for different species, stocking densities, and production requirements.
Applications:
Mechanical Filtration
Mechanical Filtration Equipment for RAS
Drum filters are used for continuous removal of suspended solids from circulating water. By removing solid waste before biological treatment, drum filters help improve:
Applications:
Organic Removal
Organic Waste Removal for Improved Water Quality
Protein skimmers remove dissolved organic matter from aquaculture water through foam fractionation technology. They are especially suitable for systems requiring:
Applications:
Gas Control
Gas Balance Management in RAS
Degassing towers remove excessive dissolved gases, especially carbon dioxide produced through fish respiration and biological processes. Proper gas management helps maintain:
Applications:
Biological Filtration
Biological Filtration for Ammonia Control
MBBR biofilters provide biological treatment through moving media carriers that support nitrifying bacteria growth. The system helps maintain:
Applications:
Disinfection
UV Water Disinfection for RAS Biosecurity and Pathogen Control
UV sterilizers reduce microorganisms in circulating water, supporting biosecurity and stable water quality in RAS. They support:
Applications:
Oxygenation
Dissolved Oxygen Management for High-Density Aquaculture
Oxygenation systems provide stable oxygen supply through PSA Oxygen Generators, Oxygen Cones and Air Suspension Blowers. They support:
Applications:
A commercial RAS operates through a continuous water treatment cycle: Aquaculture Tank → Mechanical Filtration → Organic Removal → Biological Filtration → Degassing → Oxygenation → UV Disinfection → Return Water.
Removes suspended solids generated from feed waste and fish metabolism.
