Access to clean water is a fundamental necessity, but in many coastal and island regions, freshwater resources are extremely limited. Our seawater desalination machine provides a practical and cost-effective solution by removing over 99% of salt, minerals, and other impurities from seawater, delivering high-quality fresh water that meets WHO drinking water standards.
Built with durable materials and high-performance membranes, the system is designed for continuous operation even under harsh marine conditions. The fully automated control system ensures stable performance with minimal maintenance, making it ideal for industrial, municipal, and marine applications.
process flow:
Raw water tank → Raw water pump → Sand filter → Precision filter → High-pressure pump → RO system → UV sterilizer → Product water tank
| No. | Component | Function / Description |
|---|---|---|
| 1 | Raw Water Tank | Stores raw seawater or feed water before treatment. |
| 2 | Raw Water Pump | Delivers water from the tank into the pre-treatment system. |
| 3 | Sand Filter | Removes suspended solids, sand, and large particles. |
| 4 | Precision Filter (Micron Filter) | Provides fine filtration to remove small particles before the RO unit. |
| 5 | High-Pressure Pump | Pressurizes water to the required level for the reverse osmosis process. |
| 6 | RO System (Reverse Osmosis Unit) | Removes >99% of dissolved salts, minerals, and impurities. |
| 7 | UV Sterilizer | Disinfects permeate water by eliminating bacteria and microorganisms. |
| 8 | Product Water Tank | Stores the purified freshwater ready for use or distribution. |
High Salt Rejection Rate: Removes >99% of dissolved salts and impurities.
Advanced RO Technology: Uses premium reverse osmosis membranes for superior water quality.
Robust & Corrosion-Resistant Design: Built with marine-grade stainless steel and anti-corrosion components.
