Offshore Containerised DAF + Seawater RO

Two 20ft containers, DNV 2.7-1 lift-certified, built for offshore platforms, marine vessels and coastal sites where space, weight and salt corrosion are unforgiving. One container pre-treats seawater — removing oil and solids by dissolved air flotation; the second produces potable water by seawater reverse osmosis.

Marine-grade coatings, sealed IP66 electrical enclosures and vibration-resistant mounting throughout — the same proven DAF+RO process, hardened for the offshore environment and certified for offshore lifting.

DAF Pre-Treatment + Seawater RO

Two independent, liftable 20ft containers that work as one train

  DAF Container (20ft)

Pre-treats raw seawater — removing oil and solids with a compact lamella DAF cell ahead of the membranes. ~3 m³/h, ~5.5 kW total. Protects the RO from fouling and the intake’s oil and particulate load.

  RO Container (20ft)

Seawater reverse osmosis producing ~1.5 m³/h of potable permeate from 2×8040 SWRO elements at 60 bar. Compact-scale duty (no energy-recovery device), ~11 kW high-pressure pump.

Independent operation: each container has its own controls and can run alone — useful when deck space or lifting schedules mean they arrive and install separately.

Built for Salt, Motion and Lifting

DNV 2.7-1 Lifting

Certified frames and lifting points for offshore crane handling.

Salt-Spray Resistance

Marine-grade paint and anti-corrosion coating on all exterior steel.

IP66 Enclosures

Sealed electrical enclosures rated for washdown and salt ingress.

Vibration-Resistant

Mounting designed for deck motion and transport shock.
