Aquaculture Water Treatment Plant

Aquaculture water treatment plant — intake, process and effluent treatment blueprint

Water is the single hardest asset in aquaculture. FishMatch structures water treatment plants across intake, process, RAS filtration and effluent — with the engineering, sizing and financing needed to meet EU, USEPA and local environmental standards.

Engineering

Intake: screens, sand filters, activated carbon, softening, RO (if needed)
Disinfection: UV, ozone, chlorination (broken down before use)
RAS filtration: drum, MBBR, degasser, oxygen, denitrification reactors
Effluent: solids capture, biological treatment, constructed wetlands, MRV
Full instrumentation: DO, pH, ORP, TAN, NO₂, NO₃, PO₄, turbidity

Project Budget

Line item	Low	High
Intake & pre-treatment	$0.3M	$2M
Process filtration (RAS or pond)	$0.5M	$4M
Effluent treatment & discharge	$0.5M	$3M
Instrumentation & SCADA	$0.2M	$0.8M
Engineering, permits, contingency	$0.3M	$1.5M

Total CAPEX: US$ 1.8M – US$ 11M depending on flow and treatment level

Water Requirements

Flow

50 m³/day (small hatchery) to 20,000 m³/day (large RAS or processing)

Recovery

95–99.5% on RAS; > 80% water reuse on processing

Power Requirements

Installed load

50–800 kW depending on flow

Solar

Attractive for pumping and aeration loads

Supplier Matching

FishMatch briefs 3–5 audited suppliers per package, benchmarks quotes on CAPEX / OPEX / lead time, and coordinates ECA + DFI financing across the shortlist.

ROI

Compliance value

Enables EU / US / GCC export access

Water saved

95–99.5% recirculation vs flow-through

Payback (integrated with RAS)

Built into farm economics; standalone payback via water tariff + compliance

Indicative benchmarks. Actual returns depend on species, market, offtake, financing structure and operator track record.
