What we source
FishMatch Group sources biological filtration systems for RAS and intensive aquaculture — MBBR reactors, fixed-bed towers, denitrification reactors and integrated biological water-treatment packages.
- MBBR moving-bed reactors
- Fixed-bed biofilters
- Denitrification units
- Trickling towers
- Kaldnes / K1 / K3 media
Private by design.
You'll never see supplier names. We run a sealed-bid process and present anonymized proposals — you choose the winner, we handle the introduction and the contract.
Markets we source biological filtration for
Sourcing runs the same way in every market: one structured specification, matched suppliers with real export experience for that destination, and anonymized bids priced on the same scope. Country pages below carry the local logistics, certification and installation detail.
Biological Filtration: equipment guides and planning tools
Product-type guides explain what each item does, published specification ranges and what to put in a request. Size the project with the calculators, then send one reviewed RFQ.
- RAS biofilters
Moving-bed, fixed-bed and sand filters that turn ammonia into nitrate.
Biofilter types compared
The biofilter converts ammonia from feed into nitrate. Size it from your peak daily feed, not from tank volume, and ask each supplier for the design nitrification rate and the temperature it assumes.
| Option | Typical fit | Ask the supplier to state | Watch-outs |
|---|---|---|---|
| Moving bed (MBBR) | Most commercial fish and shrimp RAS | Media type and fill, design feed load, aeration needed to move the media | Media screens and blower backup; media loss at start-up |
| Fixed / submerged bed | Smaller or stable loads, some hatcheries | Media surface area, cleaning method, solids tolerance | Clogs if upstream solids removal is weak |
| Trickling filter | Systems that also need degassing and CO2 stripping | Media height, hydraulic loading, CO2 removal claimed | Larger footprint; pumping height adds energy |
| Fluidised sand / granular | Compact systems with steady feeding | Sand size, fluidisation flow, pump redundancy | Sand loss or bed collapse if a pump stops |

Short answer
How do you source Biological Filtration for a commercial aquaculture project?
Start from the process requirement — biomass, flow, water quality target and site constraints — not from a product catalogue. FishMatch Group converts that requirement into a specification for Biological Filtration, sources it from matched manufacturers and integrators across Europe, Asia and the Americas, and returns like-for-like quotations with lead times, energy consumption and lifetime running cost stated in the same format.
- What we compare:
- Scope, capacity, energy use, lead time and total cost of ownership
- Typical turnaround:
- Depends on scope and site data; no turnaround is guaranteed
- Delivery terms:
- Quotations normalised to EXW / FOB / CIF so prices are like-for-like
- Cost to buyers:
- No fee charged to the buyer
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.
