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 et faster start/stop than traditional evaporators. The skid integrates pre-filtration, high-pressure pumping, RO membranes 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

• Controls: 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.
