Recirculating Aquaculture System with Mechanical and Biological Filtration

Recirculating Aquaculture System with Mechanical and Biological Filtration

A species- and feed-load-engineered RAS combining culture tanks, solids removal, biofiltration, gas management, disinfection, temperature control and emergency life support.

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. Circulate tank water continuously through solids-removal equipment.
2. Convert ammonia through a commissioned nitrification biofilter.
3. Strip carbon dioxide, restore oxygen and condition temperature and pH.
4. Disinfect the selected side-stream, manage sludge and monitor all critical loops.

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

• Trout and salmonid production
• Seabass and seabream nursery or grow-out
• Sturgeon and specialty finfish
• Shrimp, broodstock and quarantine systems

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

• Species, biomass, feed-load and mortality design basis
• Make-up water, discharge and sludge mass balance
• Biofilter TAN load and biological commissioning plan
• Oxygen, pumping, heating and cooling energy
• Backup power, oxygen autonomy and local service

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

• EU Aquaculture production methods and RAS components
• SRAC preferred aquaculture water-quality ranges
• EU Aquaculture RAS benefits and challenges

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.
