Aquaculture Oxygen Generation and Nanobubble System

Aquaculture Oxygen Generation and Nanobubble System

An on-site PSA or VPSA oxygen package with a selected cone, low-head oxygenator, diffuser or nanobubble contact system.

AgriTech.tr prepares this entry as a supplier-neutral technical sourcing scope so buyers can define a comparable request before suitable suppliers are researched and confirmed during sourcing. It does not reproduce a single vendor catalogue. Depending on the project, the potential scope may include local equipment and services or imported specialist components where technically necessary; the actual supplier and origin are confirmed during the quotation process.

Technical sourcing scope

The values below are not guaranteed single-model performance. They are typical, configurable procurement envelopes used to place competing quotations on the same engineering basis. Capacity, recipe, climate, water analysis, feedstock properties, target quality, utilities, and destination-country requirements are frozen in the final project schedule.

Process and integration sequence

1. Compress and condition ambient air for molecular separation.
2. Generate oxygen and verify flow, pressure and purity continuously.
3. Transfer oxygen into water through the selected contact technology.
4. Control from DO demand and switch to emergency supply upon critical faults.

The line or system boundary is documented through a responsibility matrix covering reception and infeed, process equipment, automation, safety, product discharge, utility interfaces, and data records. For brownfield integration, electrical single lines, piping and instrumentation, floor/loading data, drainage, ventilation, water quality, compressed air, steam, refrigeration, and network interfaces are reviewed before order.

Suitable applications

• Recirculating aquaculture systems
• Fish hatcheries and nurseries
• High-density ponds and tanks
• Live-fish holding and emergency oxygen

Engineering, compliance, and acceptance

• Quotations are compared against the same feed or product specification, inlet condition, shift pattern, net capacity, and target output quality.
• Food-contact materials, machine safety, electrical panels, pressure equipment, refrigerants, emissions, occupational safety, and hygienic design are specified for the destination and the actual process risk.
• Factory and site acceptance tests define the measurement method, sample size, tolerances, run duration, rejection criteria, and correction period in writing.
• The procurement dossier requests a revision-controlled technical schedule, equipment and motor lists, material specifications, utility consumption, critical spares, preventive maintenance, manuals, and operator training.
• Capacity, yield, energy, water, product-loss, quality, or biological-performance statements are not treated as guarantees without the actual design inputs and an agreed acceptance test.

How to compare quotations

• Oxygen output and purity across turndown
• Corrected transfer efficiency at site salinity and temperature
• Specific power in kg dissolved O₂/kWh
• Compressor redundancy, noise and maintenance
• Emergency oxygen autonomy and service response

Buyers should request at least three comparable quotations, references for similar installations in Türkiye, CE/conformity documentation, warranty boundaries, critical-spares lead times, and after-sales response commitments. This makes lifecycle cost, operability, and local service capacity visible alongside the purchase price.

Technical references

• FAO aeration and oxygenation in aquaculture
• FAO intensive-aquaculture life-support technology
• SRAC aquaculture water-quality ranges

The references support process principles and design boundaries; they do not certify a particular supplier’s performance. Final acceptance is based on the selected supplier’s written offer, project engineering, site review, and FAT/SAT protocol.
