Marine Desalination Plant

Marine Desalination Plant | 30 m³/Day Reverse Osmosis System for Ships & Offshore Use

High-Efficiency Sea Water Desalination System for Marine Freshwater Production

Our Marine Desalination Plant delivers reliable, high-quality freshwater production through advanced reverse osmosis technology. Designed specifically for marine and offshore applications, this system efficiently processes seawater with salinity up to 38,000 ppm, producing up to 30 m³ of fresh drinking water daily that complies with WHO standards (TDS ≤500 ppm).

Built with premium corrosion-resistant materials and featuring comprehensive automation and protection systems, this desalination plant ensures operational reliability and minimal maintenance in the most demanding marine environments.

Key Features & Benefits:

Premium RO Technology: Single-stage reverse osmosis with ≥99% desalination rate
Intelligent Protection Systems: Automatic shutdown for over-pressure (≥6.5 MPa) and low inlet pressure (≤0.05 MPa) conditions
Semi-Automatic Maintenance: Compressed-air-accelerated sand filter backwashing system
Real-Time Monitoring: Online conductivity meter and comprehensive instrumentation for continuous performance tracking
Marine-Grade Materials: SS316, glass fiber, and PPR components for corrosion resistance
Compact & Robust Design: Optimized footprint for easy installation aboard vessels and platforms
