Marine Sea Water Desalination Unit

Marine Sea Water Desalination Unit | 60 m³/Day Reverse Osmosis System for Ships & Offshore Platforms

Advanced Reverse Osmosis Desalination System for Marine Freshwater Production

Our Marine Sea Water Desalination Unit is engineered to convert seawater into high-quality drinking water that meets WHO standards, making it ideal for vessels and offshore installations operating in saline environments. Designed to handle seawater with salinity up to 38,000 ppm, this robust system produces up to 60 m³ of fresh water per day with a salt content of ≤500 ppm—ensuring a reliable supply of potable water for crew consumption and operational needs.

With features including semi-automatic cleaning, comprehensive pressure protection, and corrosion-resistant components, this system delivers exceptional performance, durability, and compliance with international marine standards.

Key Features & Benefits:

High-Efficiency Reverse Osmosis: Single-stage RO process with ≥98.5% desalination rate.
Intelligent Protection Systems: Automatic shutdown for over-pressure (≥6.5 MPa) and low inlet pressure (≤0.05 MPa) conditions.
Semi-Automatic Backflush & Cleaning: Compressed-air-accelerated sand filter cleaning extends membrane life and maintains efficiency.
Real-Time Monitoring: Integrated conductivity meter and flow meters for continuous water quality and performance tracking.
Marine-Grade Construction: Corrosion-resistant materials (SS316, UPVC, PPR) ensure longevity in harsh environments.
Energy-Efficient Operation: Low power consumption (22 kW including boost pump) with IP56-rated F-class insulation motors.
