Request matched quotesShort answer
How much does a plant utilities & effluent treatment cost?
- Water use:
- 3–8 m³ per tonne raw material (fish), 5–12 m³ (peeled shrimp)
- Effluent load:
- COD 2,000–8,000 mg/L untreated seafood processing wastewater
- Budget share:
- Utilities + effluent typically 20–35% of total equipment CAPEX
- Water reuse:
- 20–40% reduction achievable with segregation and reuse design
Throughput and indicative CAPEX bands
Indicative equipment supply only (EXW/FOB). Building, civil works, duties and local installation are additional.
| Scale | Throughput | Indicative CAPEX | Typical scope |
|---|---|---|---|
| Screening only | up to 100 m³/day | USD 20k–70k | Rotary/drum screens and solids handling; often the legal minimum. |
| Screening + DAF | 100–500 m³/day | USD 90k–350k | Removes fats, oil and suspended solids to municipal discharge limits. |
| Biological | 500–2,000 m³/day | USD 400k–1.5M | MBBR/SBR for direct discharge or reuse; needed for strict permits. |
| CIP & utilities | Plant-wide | USD 60k–400k | CIP skids, chill water, compressed air, steam and hot-water systems. |
What a complete scope must cover
Chill water
Chillers and ring mains keeping product below 4 °C throughout the line.
CIP & hygiene
Central or satellite CIP, foam stations, boot washers and hygiene zoning.
Steam & hot water
Boilers for cooking, sterilisation and cleaning; heat recovery cuts OPEX materially.
Effluent treatment
Screening, fat and oil removal via DAF, and biological polishing where required.
Solids handling
Screened solids routed to by-product recovery rather than landfill wherever possible.
Machine, line, turnkey plant or EPC scope?
Compare offers at the same responsibility level. A low machine price is not comparable with a line that includes controls, utilities, installation and performance acceptance.
| Scope | Typically includes | Buyer retains | Use when |
|---|---|---|---|
| Single machine | One defined operation and controls | Interfaces, utilities, installation and line balance | The factory and upstream/downstream process already exist |
| Complete line | Connected process equipment, controls and throughput duty | Building, major utilities, cold store and permits unless stated | One product flow needs a measurable output guarantee |
| Turnkey plant | Line, utilities, installation, commissioning and training as contracted | Land, approvals, raw material and items expressly excluded | The buyer wants fewer package interfaces |
| EPC scope | Engineering, procurement and construction coordination under an agreed contract | Owner decisions, financing, permits and operational inputs | Civil works and multiple technical packages must be integrated |
Selection criteria
- •Local discharge limits obtained in writing before tendering
- •Segregated drains so clean and heavily loaded streams do not mix
- •Sludge and screened solids route — recovery beats disposal
- •Heat recovery from refrigeration to hot water
Costly mistakes
- •Tendering the line first and utilities later, then paying premium change-orders
- •Designing to average flow instead of peak wash-down flow
- •Assuming a municipal connection will be granted without pre-treatment
Put this in your RFQ
- •Attach measured or estimated flows, COD, FOG and the written discharge limit
- •Require guaranteed outlet quality with a performance test
- •Include sludge handling, odour and operating cost per m³ in the comparison

Request plant utilities & effluent treatment quotes
Send the species, product format, peak throughput, labour plan, automation target, hygiene standard, utilities, installation boundary and cold-chain interface. FishMatch reviews the brief and seeks matched responses; timing depends on scope and supplier interest, and identities stay confidential until you approve contact.

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.
