RAS Equipment Manufacturers — Buyer's Knowledge Page
RAS equipment manufacturers deliver integrated water reuse systems for commercial fish production. RAS is a process plant, not a piece of equipment — the wrong scope split between owner, EPC and vendor is the single biggest source of budget overrun and biological failure. This page helps commercial buyers scope, specify and tender RAS without locking in a single brand.

Typische Anwendungen
- Land-based salmon, trout, tilapia, sea bass, sea bream, barramundi, yellowtail
- Post-smolt & smolt production for open-net operators
- Broodstock and hatchery water reuse loops
- Nursery and grow-out combined units for shrimp
Projektgrößen
- Pilot & R&D: 10–50 t/year
- Small commercial: 100–500 t/year
- Mid commercial: 500–2,000 t/year
- Mega RAS: 2,000–20,000+ t/year
Auswahlkriterien
- Documented mass-balance calculation (O₂ / TAN / CO₂ / sludge)
- Reference plants of similar species, life-stage and capacity
- Guaranteed KPIs: DO ≥ 6 mg/L, TAN ≤ 1 mg/L, CO₂ ≤ 15 mg/L, availability ≥ 98.5%
- Specific energy target (kWh/kg produced) with penalty clauses
- Local service network and response time SLA
- Bankable warranty terms (biology, process, mechanical, electrical)
Fragen, die Käufer stellen sollten
- What is the mass balance per stage at peak biomass?
- What is your specific energy consumption (kWh/kg) for a comparable reference?
- What is the make-up water demand (L/kg produced) at target salinity?
- How do you handle CO₂ stripping — packed towers, cascade, forced draft?
- What is the biofilter media specific surface area and hydraulic residence time?
- How is redundancy structured for oxygen supply, pumps and blowers?
- What is your commissioning and biological start-up protocol?
- Which items are excluded from the base scope (civil, HVAC, backup power)?
Häufige Beschaffungsfehler
- Buying on price without a mass-balance basis of design
- Naming brands in Employer's Requirements (loses tender leverage)
- Ignoring make-up water quality analysis before tender
- Under-sizing backup power for oxygen and circulation
- Missing sludge, brine and effluent permit envelope
RFQ-Empfehlungen
- Publish an Employer's Requirements document (outcomes, not brands)
- Include species, life-stage, ramp-up curve and water analysis
- Require bid comparison in a common format (CAPEX + 10-year OPEX)
- Ask for warranty and performance-guarantee wording upfront
