Simple Explanation

  1. Water Quality Standards
    Seawater desalination produces water that meets strict drinking water standards. The salt content is very low, making it safe for human consumption and sensitive industrial processes.

  2. Production Technology
    The most common method is High-pressure Reverse Osmosis, which forces seawater through special membranes to remove salts. Thermal distillation is also used in some large plants. Both methods require advanced pre-treatment to protect the equipment.

  3. Main Applications

    • Drinking water for cities and coastal communities

    • Water supply for hotels and resorts

    • Industrial water for manufacturing and power plants

    • Special uses in aquaculture and agriculture

Why Choose Seawater Desalination?
Seawater desalination provides a reliable water source where fresh water is scarce. Though more expensive than treating brackish water, it produces higher quality water suitable for drinking and sensitive industrial uses
