Composite RAS Water Treatment Tanks for Land-Based Aquaculture

HighComp’s composite GRP water treatment tanks are engineered for reliable performance in land-based aquaculture and recirculating aquaculture systems (RAS), utilizing advanced composite GRP materials optimized for demanding environments.

Designed for biological and mechanical filtration, degassing and process integration, our tanks deliver corrosion-free durability, modular installation and long-term operational stability.

From standalone process tanks to fully integrated RAS infrastructure, each solution is tailored to match system design and site requirements.

Designed for RAS and Process Integration

HighComp water treatment tanks are suitable for:

Biological Filtration (Biofilters)
Optimized structural configurations for media load, water distribution and integration with all RAS suppliers.

Mechanical Filtration & Clarification
Process tanks designed to support solids removal and flow control.

Degassing (CO₂ / N₂)
Tanks engineered for efficient gas removal and stable water quality conditions.

Each tank is configured to integrate seamlessly with pumps, piping, filtration systems and overall facility layout.

Engineered for Process Performance and Reliability

Water treatment tanks operate under continuous hydraulic loads and demanding chemical environments, requiring precise structural dimensioning and composite engineering analysis.

HighComp GRP tanks deliver:

  • Corrosion-free composite construction with 50+ year design life
  • High structural integrity under sustained water and media loads
  • Smooth internal surfaces supporting hygiene and simplified maintenance
  • Flexible geometry and capacity adapted to process flow requirements

The result is stable process performance with predictable lifecycle cost.

From Engineering to Commissioning

1. Engineering & Design

Every project begins with detailed engineering aligned with process requirements and integrated into our broader EPCI aquaculture delivery model.

We collaborate with RAS technology providers and project stakeholders to ensure:

  • Load and media calculations
  • Flow distribution and structural optimization
  • Integration with civil works and piping systems
  • Compliance with local regulations and standards

Early engineering involvement reduces interface risk between structural and process systems.

2. Fabrication

Water treatment tanks are manufactured in controlled facilities as large prefabricated modules.

This approach ensures:

  • Consistent material quality
  • Dimensional precision
  • Reduced number of on-site joints
  • Improved structural alignment

Prefabrication minimizes variability and supports efficient installation.

3. Shipment

Modules are prepared for transport by truck or vessel depending on project location.

Prefabricated sections reduce transport complexity while maintaining structural integrity. Coordinated logistics planning aligns delivery with site readiness and installation sequencing.

4. Installation

Because tanks are produced in large modules, on-site assembly is streamlined.

Fewer structural connections result in:

  1. Faster installation
  2. Reduced margin for error
  3. Lower exposure to weather-related delays
  4. Efficient alignment with piping and process systems

Structured installation planning supports predictable commissioning timelines.

5. Inspection & Quality Assurance

Quality assurance is integrated throughout engineering, fabrication and installation.

In addition to operating under ISO-certified management systems (ISO 9001, ISO 14001, ISO 45001), each delivered facility undergoes project-specific inspection and documentation procedures.
