Калькулятор расхода воды и кислорода УЗВ (RAS) — предварительная оценка
Проектный расход — большее из двух: расход, переносящий кислород (потребность ÷ допустимое падение O₂), и расход по обороту бассейнов. Потребность считается как корм × кг O₂ на кг корма; предложенное 0,25 — опубликованное плановое значение, его можно изменить.
Предварительная оценка. Результаты не являются проектом, коммерческим предложением или прогнозом и должны быть проверены квалифицированным инженером до решения о закупке или финансировании.
Заполните все поля, чтобы увидеть результат. Значения не подставляются: используйте собственные проектные данные или цифры поставщиков.
Методика и формулы
Все данные — ваши. В инструменте нет встроенных значений урожайности, выживаемости, кормового коэффициента, цен, энергии или ставок финансирования.
- Потребность O₂ (кг/сут) = корм (кг/сут) × кг O₂ на кг корма
- Расход по кислороду (м³/ч) = потребность O₂ (кг/ч) × 1 000 ÷ (O₂ вход − O₂ выход) [мг/л = г/м³]
- Расход по обороту (м³/ч) = объём (м³) × оборотов в час
- TAN (кг/сут) = корм × доля протеина × 0,092 (Timmons, Ebeling 2010)

Short answer
What is the fastest way to get quotes for RAS Flow Oxygen?
Submit one structured request for RAS Flow Oxygen. FishMatch Group translates it into a technical RFQ, runs a confidential sourcing round with project-matched international suppliers, and returns comparable quotations. No fee is charged to the buyer, and your identity and project details stay private until you choose to proceed.
- How it works:
- One structured request, human-reviewed before any supplier outreach
- Typical turnaround:
- Depends on scope and site data; no turnaround is guaranteed
- Confidentiality:
- Supplier names are never exposed during evaluation
- Cost to buyers:
- No fee charged to the buyer

How does FishMatch Group source suppliers for this requirement?
You submit one structured request. We translate it into a technical RFQ, run it against qualified manufacturers and integrators in the relevant categories, and return normalised quotations you can compare side by side on scope, lead time and total cost of ownership.
Do buyers see supplier names during the sourcing process?
No. Supplier identities stay confidential during discovery and evaluation. You receive anonymised, comparable technical and commercial packages, and introductions happen only after both sides are qualified and agree to proceed.
Before you request quotes
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.
