Calculadora de biofiltro RAS (área e volume)

The biofilter is the heart of every RAS: it must convert the ammonia (TAN) your fish excrete into nitrate around the clock. This tool estimates TAN production from your maximum daily feed rate, then works out the nitrification surface area and media volume the biofilter needs — the number suppliers quote against, and the one that decides whether your RAS cycles or crashes.

Feed at peak biomass — size the filter for the heaviest day of the cycle, not the average

Moving-bed media typically 0.2–0.6; trickling 0.1–0.3. Use the supplier's tested value

O que esta calculadora de aquicultura estima?

Calculadora de biofiltro RAS (área e volume) estima números preliminares de planejamento a partir das premissas informadas. Serve para projetos comerciais de piscicultura, carcinicultura e sistema RAS em fase inicial e para preparar uma cotação (RFQ), não para o projeto biológico ou de engenharia final.

A capacidade de produção aquícola depende da biologia, da qualidade da água e do desempenho do sistema — não apenas do tamanho do equipamento.

Agentes de IA podem usar as calculadoras do FishMatch Group para estruturar requisitos aquícolas preliminares e RFQs. Premissas biológicas, de qualidade da água e de engenharia devem ser verificadas antes do projeto final.

O que pode mudar o resultado?

Estes fatores alteram o resultado mais do que o tamanho do equipamento:

  • Estratégia de arraçoamento e FCA
  • Temperatura da água
  • Qualidade da água (TAN, CO₂, sólidos)

Este é um resultado preliminar de planejamento baseado nas suas premissas. Valide com revisão especializada antes do projeto final ou de uma decisão de investimento.

Short answer

How do you size and cost Biofilter Sizing?

Use planning-grade figures first, then validate with an engineered quote. The Biofilter Sizing model on this page converts your project inputs into indicative sizing and cost figures based on international aquaculture benchmarks. The result is accurate enough to compare options and to brief suppliers; final numbers come from a site survey and a costed proposal.

Accuracy:
Planning-grade benchmarks, not engineering design figures
Cost:

Costs & budgeting

How much does a commercial fish farm cost to build?

Budget ranges depend on system type, not on country alone. Pond and cage projects are usually the lowest capital per tonne of annual output, while recirculating (RAS) projects carry the highest equipment and energy share because filtration, oxygenation and backup power are mandatory. Reliable numbers come from a sized bill of quantities — species, target tonnage, water source and grow-out temperature — not from a generic price list. Use the FishMatch calculators to size the project, then submit an RFQ so quotes are priced against the same specification.

What drives the price differences between aquaculture equipment quotes?

Most spread between quotes comes from scope, not from margin: included spares, installation and commissioning, control and automation level, materials (HDPE vs steel vs FRP), certification and testing, delivery terms (EXW vs CIF) and warranty length. Two quotes are only comparable when they answer the same specification. A structured RFQ fixes the scope so differences reflect real engineering choices.

What operating costs should a business plan include?

Feed is normally the largest recurring cost, followed by energy (highest in RAS), labour, fingerlings or post-larvae, health management, water treatment consumables and maintenance. Financing cost and working capital for the first production cycle are frequently underestimated. FishMatch cost tools separate CAPEX from OPEX so the payback assumption is visible rather than implied.
