OUR APPROACH
How we design a custom aquaculture circuit
An engineering method, from the first conversation to commissioning — never a standard configuration.
-
Need analysis and biological constraints
Start from the living animal: organic load, tolerance to NH₃/NO₂, target temperature and salinity.
We start from the living animal. The organic load it generates, its tolerance to nitrogen compounds (ammonia NH₃, nitrites NO₂), and the target temperature and salinity set the parameters for the entire circuit. This biological reading drives the sizing of mechanical filtration, biological filtration and protein skimming. Designing without it means oversizing for safety — at the cost of energy and water consumption.
-
Hydraulic sizing
Flow rates, turnover times, head losses — calculated for actual use.
Flow rates, turnover times, drop heights, head losses: the hydraulic circuit is calculated for its actual use. The selection and positioning of MAELSTRÖM (external, counter-current) and NAUTILUS (internal, instant skimming) skimmers, pumps and filtration stages follow directly from this calculation, with a constant goal of energy efficiency and a stable environment.
-
Materials and design
Thermoplastic and FRP materials, drawings validated with the client before fabrication.
Our installations are fabricated in thermoplastic (polypropylene, PVC, HDPE) and composite (FRP) materials, chosen for their compatibility with seawater and sanitary requirements. Technical drawings, filtration schematics and renders are produced in-house, then validated with the client before fabrication begins. Nothing is locked in until the sizing has been shared and understood.
-
Integrated fabrication and installation
Same teams, no subcontracting: a single point of contact from sizing to water-filling.
A distinctive trait of Aquaculture Solutions: design, fabrication, industrial piping, waterproofing, electrical work and commissioning are all handled by the same teams, without industrial subcontracting. The client has a single point of contact from sizing to water-filling, which reduces interfaces, lead times and grey areas of responsibility between trades.
An aquaculture engineering office does not sell a catalogue: it sizes an installation for a given species, biomass and site constraint. At Aquaculture Solutions, every project begins with an analysis of the real need — species reared or stored, target volumes, incoming water quality, building constraints and operating objectives. This step determines whether the answer is a recirculating aquaculture system (RAS), a live storage tank, a hatchery or a shellfish purification system.
PROJECT EXAMPLE
A seawater circuit designed for research, in Alsace
For Domiconus, in Obermorschwiller (Haut-Rhin), we designed and built a complete seawater production circuit for research — several hundred kilometres from the coast. The project captures the core of the engineering office's work: recreating and stabilising a controlled marine environment where it does not exist naturally, integrating water production, filtration and parameter regulation.
Other studies extend this expertise by sector: the complete refurbishment of an AFM (activated sand) filter for the CNRS Biological Station in Roscoff, the custom industrial live storage tanks fitted with real-time monitoring for E.Leclerc in Plérin, or the refurbishment of Océalliance's stacked live tanks in Penmarc'h. Each study starts from the same engineering principles, adapted to the species, volume and site constraints.
