Built Around Your Requirements
We Start With Your Production Requirements, Not an Equipment List
A RAS is more than a collection of tanks and water-treatment equipment. Each treatment process must be sized and integrated around the biological, production and site requirements of the project.
SpeciesWhat species will the system support?
Production TargetWhat production capacity is planned?
Biomass & Stocking DensityWhat biological load must the system handle?
Feed LoadWhat waste and ammonia load must be treated?
Water SourceFreshwater, seawater or brackish water?
Site ConditionsWhat facility and operating conditions must the system work within?
Engineering Step

How We Work
From RAS Design to Project Implementation
A RAS project moves through connected engineering and implementation stages. Project requirements form the basis for the system and equipment needed to support it.
01
02
Design
We develop the treatment process, system configuration and equipment requirements around the needs of the project.
03
Build & Integrate
Core RAS equipment is manufactured and integrated according to the overall system design.
04
Install & Implement
The system moves from engineering and equipment preparation into on-site installation and project implementation.
Integrated RAS System
How the Major RAS Processes Work Together
Each treatment stage performs a different function. The complete system must integrate these processes so water can be continuously treated and returned to the culture tanks.
Simplified process overview. Treatment stages and equipment configuration depend on the requirements of each project.

Land-Based RAS Experimental Center
Our experimental center provides a practical setting for developing RAS equipment and system designs. By observing how water treatment processes work together, our engineers can identify operational challenges and use what they learn to improve future solutions.
Land-Based Internal-Circulation Aquaculture Base
Our aquaculture base keeps system design connected to daily farming. It gives our team a place to observe how feeding, waste removal and routine management affect system operation, helping us design solutions with practical use and maintenance in mind.

RAS Project FAQ
Questions Before Starting a RAS Project
01 Can YUTANK design a complete RAS system for my project?
YUTANK's current capabilities include RAS system planning, engineering design, equipment manufacturing, equipment integration, installation and project implementation. The system configuration is developed around the requirements of the individual project.
02 What information do you need to plan my RAS?
Useful starting information includes the species, target production capacity, expected biomass or stocking conditions, water source, project location, facility conditions and current project stage. You do not need to have every technical parameter finalized before contacting us.
03 Do I need to know what RAS equipment I need before contacting you?
No. We can start with your production and project requirements before defining the appropriate treatment processes and equipment configuration.
04 Can I purchase individual RAS equipment?
Yes. In addition to integrated RAS projects, YUTANK supplies individual RAS equipment for specific water-treatment requirements.
05 Does YUTANK provide RAS installation?
Yes. Installation and project implementation are included within YUTANK's current RAS project capabilities. Detailed international installation arrangements should be confirmed for each project.
06 How do I start discussing a RAS project with YUTANK?
Start with the information you already have: species, production goals, project location, water source, facility conditions and current project stage. A complete equipment list is not required.
