Design & engineering

From the first drawing to a running farm.

Many RAS problems are built in on day one: undersized biofilters, poor flow, a financing gap or a crew left alone after handover. We engineer them out — from the first drawing to a running farm.

Where projects go wrong

Fix it on paper, not in the water.

Problem

Undersized water treatment

Biofilters, oxygenation and degassing sized by rule of thumb fall short as the biomass grows.

With Suderra

We size flow, biofiltration, oxygenation and degassing to your species and density — and validate the design in CFD.

Problem

A site that underperforms

Water quality swings, losses and rising costs at an existing facility, with no clear cause.

With Suderra

An independent audit of water balance, biosecurity and risk, with a prioritized roadmap.

Problem

Financing that stalls the project

A good project waits while the capital is arranged.

With Suderra

We help you secure Eksfin-backed financing — 90% for projects under €2M, 60–70% above.

Problem

A crew left alone after handover

New systems struggle when the people running them never learned how.

With Suderra

We support construction and commissioning, and train your team to run the system with confidence.

End to end

We design it, audit it, and sense it.

From the first drawing to live operation, Suderra stays in the loop — we design, help you audit, finance, build and run, and keep the water honest with sensors and AI.

    Sense & decide

    Suderra Edge reads your existing sensors continuously and AI turns the data into decisions you approve.

Engineering scope

Sized to your species, your site and your scale.

Flow & hydraulics

Water velocity and bottom-drain design, validated in CFD simulation and in the field.

Biofiltration

3–4 biofilter stages, sized to your species and stocking density.

Oxygenation & degassing

Oxygenation and CO₂ degassing sized to your species and stocking density.

Water balance
