Anyone can bolt a flotation cell into a container. Building a seawater DAF pilot that runs reliably for months on a corrosive, biologically active feed — and produces data you can stake a plant on — is an engineering discipline. This is how Reynolds & Bauhm designs, fabricates, wires, programs and factory-tests every rig, and why each one arrives as a known-good unit.
When you hire or buy a pilot, you are really buying confidence that the people behind it can deliver the full plant too. So we build the pilot the way we build production equipment: designed from first principles, fabricated in materials chosen for seawater service, wired and programmed in-house, and proven on clean water before it ships. The same engineering capability described in our bespoke design services and bespoke manufacturing goes into every pilot.
P&ID, mass balance, 3D container/skid layout and instrument schedule — modelled and clash-checked in 3D before any steel is cut.
SS316, super-duplex and HDPE fabrication for chloride service, coded welding and the container fit-out — our core DAF manufacturing capability.
Pre-piped process skids, marine-grade cabling, IP55 panels and single-point service connections for plug-and-play on site.
PLC programming, HMI screens, data historian and remote access written in-house — see bespoke automation.
Witnessed factory acceptance test on clean water, full QA dossier, as-built drawings and O&M documentation.
Seawater is unforgiving — material selection is not optional
| Component | Material | Why |
|---|---|---|
| DAF cell & floc tanks | SS316L / super-duplex | Chloride pitting resistance at the flotation interface |
| High-pressure saturator | Super-duplex / coated | Pressure + chloride + dissolved oxygen |
| Chemical wetted parts | PVDF / PTFE / HDPE | Ferric, acid and caustic compatibility |
| Pumps & valves | Duplex / SS316 / non-metallic | Seawater duty, no galvanic traps |
| Panels & enclosures | 316 / GRP, IP55 | Salt-laden marine atmosphere |
| Fasteners & supports | A4-80 / SS316 | Avoid crevice & galvanic corrosion |
Every circuit pressure-tested; saturator and high-pressure lines certified.
Pumps, mixers, skimmer, dosing and saturator run on clean water; performance verified.
Every instrument, interlock, alarm and remote-access function proven on the HMI.
You (or your representative) witness the FAT — in person or by video — before dispatch.
As-builts, material certs, calibration records, O&M manual and spares list.
Secured for transport and shipped as a single tested unit — ready for fast deployment.

Send your influent analysis and our engineers assess your process and recommend a tailored treatment solution — free, confidential and no obligation.
Select the regulatory standard for your country — it sets which parameters we need for a compliance-aware process assessment.
Required parameters for the chosen standard are flagged on the sample form. You can still submit a partial set and we will advise what else to test.
Your sample is stored against your company so we can track the project. Provide a company name or email as a minimum.
