🌞 Solar-Thermal Desalination at a Glance

A fully renewable system that evaporates seawater using solar heat and condenses it into fresh water — with no external electricity or fossil fuels. By recovering steam, it co-generates clean power and potable water. Its modular, passive design makes it scalable from small off-grid units to large community installations.

🌍 System Overview

A solar-thermal desalination system that turns seawater into fresh water using only the sun — no external power, no fossil fuels.

By recovering steam, it produces both clean electricity and potable water.

Its modular and passive design makes it scalable, from small off-grid units to large community systems.

⚙️ System Schematic

The system integrates solar collectors, evaporators, condensers, and optional turbines to create a closed water–steam–energy cycle.

It shows how seawater enters, turns into steam, generates power, and becomes fresh water.

🔑 Key Components

Seawater Intake – filtered water in
Collector-Evaporator – heats and evaporates seawater
Moisture Separator – improves steam quality (optional)
Turbine-Generator – produces electricity (optional)
Condenser – converts steam into fresh water
Salt Outlet – directs brine to solar ponds

🌞🌙 System Operation

Daytime: Collector–Evaporator heats brine → saturated steam → moisture separation → condenser (freshwater). Optional micro-turbine for electricity.
Nighttime: Radiative cooling creates vacuum → check valve opens → seawater passively refills the evaporator (no pumps).
Concentration Mode: Brine is retained and further concentrated → sent to solar ponds for salt recovery.
