UV Disinfection Systems for Aquaculture — Buyer's Guide
UV disinfection reduces pathogen loads without residuals. Effective sizing depends on UV transmittance (UVT) of your actual water and validated target dose per pathogen — not brochure numbers.
FishMatch Group is supplier-neutral. This page is educational content for buyers — not legal advice, not a supplier ranking.
How do you disinfect water on a fish or shrimp farm?
Most farms disinfect intake and recirculated water with UV, sometimes with ozone in RAS, after mechanical filtration has removed solids. UV is sized on flow, water clarity (UVT) and the dose needed for the target pathogens. Water disinfection is one part of biosecurity, alongside screened stock, equipment disinfection and controlled access.
Send a uv disinfection systems requestWhat determines UV and disinfection system size
Flow rate
UV and ozone are sized on the water flow passing through them, so the system must handle peak flow, not average flow.
Water clarity (UV transmittance)
Cloudy water blocks UV. Good mechanical filtration before UV lets a smaller unit reach the required dose; poor filtration means a much larger unit.
Required dose
Killing bacteria needs a lower dose than killing parasites or some viruses. Ask suppliers for the validated dose at end of lamp life, not with new lamps.
Typical applications
- Intake water disinfection
- RAS side-stream disinfection
- Effluent for permit compliance
Project sizes
- Small: $10K–$100K
- Commercial: $100K–$2M
Selection criteria
- Validated dose delivery at design UVT and flow
- Medium- vs low-pressure lamp selection
- Wiper / CIP for scaling water
- Redundancy and alarms
Questions buyers should ask
- Independently validated dose curve for my UVT?
- Lamp lifetime and replacement cost?
- How is dose failure alarmed?
Common procurement mistakes
- Sizing on nominal dose without UVT measurement
- Missing lamp cleaning mechanism in scaling water
RFQ recommendations
- Publish target log-reduction and design UVT

Short answer
How do you find and compare UV Systems suppliers?
You publish one structured requirement instead of contacting vendors one by one. FishMatch Group turns your UV Systems brief into a technical RFQ, runs it against qualified international manufacturers, integrators and EPC contractors, and returns normalised quotations you can compare on scope, lead time and total cost of ownership. Supplier identities stay confidential until both sides are qualified and agree to proceed.
- Coverage:
- Manufacturers, integrators and EPC contractors matched to each project
- Typical turnaround:
- Depends on scope and site data; no turnaround is guaranteed
- Confidentiality:
- Buyer and supplier identities stay private until both sides agree
- 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.
Supplier selection criteria
How should a buyer compare aquaculture suppliers?
Compare on evidence, not on presentation: delivered projects at a similar scale and climate, engineering support during design, lead time commitments, spare-part and service availability in your region, certification and testing documentation, payment and warranty terms, and willingness to quote against your specification rather than substituting a catalogue package.
What are the warning signs in a supplier quotation?
Treat these as review triggers: no itemised scope, guaranteed biological or financial performance, no named delivery terms or lead time, no spare-parts or service statement, unclear responsibility for installation and commissioning, and equipment sizing that does not reference your water temperature, oxygen demand or biomass targets.
How does FishMatch handle supplier selection?
FishMatch is an independent sourcing service, not a manufacturer or reseller. The buyer submits one structured project request; our team reviews it first and only then contacts suitable suppliers on the buyer's behalf, presenting their responses through FishMatch in a comparable format. Buyers do not contact suppliers directly and nothing is sent automatically. The final choice stays with the buyer.
