Desalination System for Ships | Seawater to Drinking Water Generator for Ships & Offshore Use

Our Desalination System for Ships is a high-efficiency ship desalination system designed to convert seawater with salinity levels between 35,000–38,000 ppm into clean, safe drinking water that complies with WHO Drinking Water Standards (TDS ≤ 600 ppm). Ideal for marine and offshore applications, this system ensures reliable freshwater production even in challenging environments.

Built with durability and user-friendly operation in mind, the system includes a one-year warranty on core components—including membranes, high-pressure pumps, and piping—when operated in accordance with manual guidelines. It supports stable performance within an ambient temperature range of 0–45°C and seawater temperatures between 5–35°C.

Key System Features & Capabilities

  • Robust Pre-Treatment & Automation: Integrated raw water boosting, multi-stage filtration, semi-automatic cleaning, and compressed-air accelerated sand filter back-flushing.

  • Intelligent Monitoring & Safety Controls: Equipped with an online salinity monitor, over-pressure protection (auto-shutdown above 6.5 MPa), and low-pressure protection to prevent dry running.

  • Real-Time Performance Tracking: Monitor operating pressure, product/brine flow, and water conductivity for optimized system control.
