Product Beschrijving

Shipboard Reverse Osmosis for Reliable Freshwater at Sea

Designed for engine-room conditions, the STARK Marine RO converts seawater into potable water with lower energy use en faster start/stop than traditional evaporators. The skid integrates pre-filtration, high-pressure pumping, RO-membranen and remineralization, with online conductivity and ΔP monitoring to keep OPEX predictable.

Why choose Marine RO over evaporators

  • Lower energy & heat load in the engine room

  • Compact footprint and modular expansion (parallel skids)

  • Simpler maintenance with standard filters and CIP ports

  • Better water quality control with continuous TDS monitoring

Marine-grade construction

  • Materials: 316L or duplex 2205/2507 options, A4 fasteners

  • Controles: PLC + HMI, auto-flush, alarms, optional VFD

  • Protection: IP54/IP55 electricals, anti-vibration mounts, corrosion-resistant coating

  • Docs: GA drawings, nozzle plan, P&ID, IOM, FAT/SAT templates for class compliance

Operations & OPEX

Auto-flush and lay-up routines minimize fouling during port stays or off-season. Typical specific energy: 3.5–5.5 kWh/m³ (temperature and recovery dependent). Consumables (cartridge filters, antiscalant) are standard marine supplies; membranes are compatible with major brands.

Note: Capacities and energy values vary with seawater temperature, TDS and recovery setpoint. Contact us for sizing based on crew number and route.

FAQ

De levensduur van een omgekeerd osmose systeem hangt af van de waterkwaliteit en het onderhoud. Het membraan gaat meestal 2-3 jaar mee, terwijl het systeem zelf meer dan 10 jaar kan meegaan als het goed onderhouden wordt.
