Oxígeno disuelto — el KPI que nunca deja de importar
Especies de agua fría OD ≥ 8 mg/L; RAS templado 5–7 mg/L; camarón 4–5 mg/L.

Calidad de agua, oxígeno y filtración
El manejo de calidad de agua es el mayor determinante operativo de productividad acuícola — oxígeno disuelto (OD), amonio (TAN), CO₂, pH y TSS controlan la biología de cada tanque o estanque sembrado.
Filtración mecánica: tambor, disco o bead?
Los tambores dominan por encima de 100 m³/h con mallas de 60–90 µm.
Biofiltración: dimensionar la capacidad nitrificante
MBBR con 500–800 m²/m³ es el estándar RAS.
Stripping de CO₂ y control de pH
Torres empacadas o cascadas reducen CO₂ de 15+ a < 8 mg/L.
Desinfección: UV, ozono o ambos
UV mata patógenos sin residuo. Ozono oxida orgánicos. Los RAS bancables combinan ambos.

Buyer-first · Supplier-neutral
One RFQ. Multiple project-matched suppliers. Zero cost to buyers.
Short answer
What do buyers need to know about Water Quality Oxygen Filtration?
Water Quality Oxygen Filtration affects both project cost and project risk, so it belongs in the specification stage rather than the purchasing stage. This page sets out what commercial buyers assess, what typically drives cost and lead time, and which questions to put to suppliers before signing. You can turn any of it into a confidential RFQ in a few minutes.
- Who it is for:
- Investors, operators and project developers specifying commercial systems
- Cost drivers:
- Capacity, water source, energy price, permitting and logistics
- Next step:
- Turn the requirement into a confidential RFQ
- Cost to buyers:
- No fee charged to the buyer

Equipment scope
What equipment does a commercial aquaculture project actually need?
A grow-out project typically needs holding infrastructure (tanks, ponds or cages), water movement (pumps, piping, valves), aeration or oxygenation, water treatment appropriate to the system, feeding equipment, grading and handling gear, monitoring and alarms, and backup power. RAS adds mechanical filtration, biofiltration, degassing, disinfection and tighter process control. Hatchery and processing scopes are specified separately.
Which equipment should be specified before requesting quotes?
Specify the items whose sizing changes everything downstream: design biomass and stocking density, water exchange or recirculation rate, oxygen demand at peak temperature, and installed pumping head. With those four fixed, suppliers can quote aeration, filtration, pumps and power on the same basis. FishMatch calculators produce these figures and attach them to the RFQ.
Can equipment be sourced in stages?
Yes, and phased procurement is common. The usual sequence is water supply and holding infrastructure, then aeration and treatment, then automation and monitoring, then processing and cold chain. Staging works when interfaces and capacity headroom are defined at the start; otherwise later phases force replacement rather than addition.
