RAS and flow-through hatchery engineering in Chile
RAS and flow-through hatcheries: intakes, water treatment, recirculation and discharge.
What we do
We design the hydraulic infrastructure of hatcheries and processing plants: freshwater and seawater intakes and pumping, supply mains and distribution to rooms and tanks.
Water treatment with drum filters, UV reactors, degassers, reverse osmosis and iron/manganese removal; recirculation (RAS), incubation and fry rooms, chilling systems, lime and oxygen networks.
Effluent discharges, outfalls and sludge treatment.
When you need it
- For new facilities and expansions.
- When an existing facility does not deliver the expected flow or water quality.
- To prepare an environmental impact declaration (DIA) or regularise works before the health authority and the DGA.
Software and standards
EPANET, HEC-RAS, OpenFOAM (CFD), Revit MEP and in-house spreadsheets. Chilean water standards, RIDAA, D.S. 90 and D.S. 46, and equipment suppliers’ criteria (Billund, Atlantium, Hydrotech, among others).
Typical deliverables
- Water balance and flows per room
- Hydraulic report with pump duty points
- BIM model of internal and external networks
- Construction drawings and specifications
- Support during commissioning and handover
What we need from you
Site layout, biomass and exchange or recirculation rates, selected equipment, topographic survey, water source and available water rights.
Timelines
They range from a one-off network check to full hatchery engineering, and are set per stage in the proposal.
Frequently asked questions
Do you work with the RAS technology supplier?
Yes. We coordinate with the recirculation system designer and deliver everything outside their scope: intakes, external networks, discharges, utilities and civil works.
Can you review an existing facility?
Yes. We survey the network, model current operation and propose improvements to pumping, discharge or distribution.
Do you deliver BIM models?
Yes. Hatchery projects are developed in Revit and coordinated with the other disciplines.
