The complete triple-barrier seawater pilot — coagulation, dissolved air flotation, ultrafiltration, cartridge guard and reverse osmosis — engineered into one containerised train that takes raw intake water through to drinking-quality permeate. It is the single most convincing thing you can put in front of a financier, a regulator or an EPC tender: a working desalination plant in miniature, on your seawater, producing your numbers.
Each barrier removes what the next cannot tolerate. DAF floats off algae, TEP and oil during a bloom. Ultrafiltration delivers a guaranteed SDI₃ and a sharp particle cut to the membranes. Reverse osmosis then proves permeate quality, flux and fouling rate on water that has actually been pre-treated the way the full plant will treat it. Running the three together — on live seawater, with every stream instrumented — is the only way to see how the barriers interact across a full season, and the only data an RO membrane warranty should ever be written against.

Strainer, VFD feed pump and inlet flow meter set the train throughput on live seawater.
FeCl₃/PACl dosing, rapid mix and tapered flocculation prepare the water for flotation.
High-rate flotation floats algae, TEP and oil to a skimmed surface layer. The bloom-resilient first barrier.
4–6 bar air saturation on an 8–15% recycle generates the micro-bubble cloud.
Hollow-fibre UF takes DAF-clarified water to a guaranteed SDI₃ with automatic backwash and CEB.
5 µm guard with ΔP logging — the final safety net before the membranes.
SWRO array proves permeate TDS, normalised flux and fouling rate on the pre-treated water.
Optional ERD on the reject stream demonstrates specific-energy figures representative of the full plant.
One PLC/HMI runs all three barriers and logs every stream — flows, pressures, turbidity, SDI₃, TMP, flux, TDS — with remote access.
Per-barrier sampling, jar test, turbidimeter, SDI₃ and conductivity for on-site analysis.
Marine-grade MCC, VFDs, single power inlet and generator interface for off-grid intakes.
Establishes the coagulant dose, recycle ratio and surface loading that hold float quality through a bloom — and the clarified turbidity handed to UF.
DAF EquipmentProves the SDI₃, sustainable flux, TMP rise and backwash/CEB strategy that deliver RO-grade feed without premature membrane replacement.
UF Pre-treatmentConfirms permeate TDS, normalised flux decline and specific energy — the figures that underwrite the membrane warranty and the business case.
RO Protection| Stream | Logged parameters | Decision it informs |
|---|---|---|
| Raw intake | Turbidity, temperature, conductivity, algae count, oil | Design basis & seasonal envelope |
| Post-DAF | Turbidity, residual coagulant, float quality | Coagulant dose & DAF loading limit |
| Post-UF | SDI₃, turbidity, flux, TMP, backwash frequency | UF flux & CEB strategy |
| RO permeate | TDS, conductivity, normalised flux, boron (opt.) | Product quality & membrane selection |
| RO reject | Pressure, recovery, specific energy | Recovery & energy design |
The DAF–UF–RO pilot is the strongest evidence you can hand a board, a lender or a regulator. Tell us the intake and the decision you need to make, and we will build the train that makes it.
