Portugal, with its long coastline and Mediterranean climate, faces growing water scarcity challenges due to climate change, irregular rainfall, and rising urban and agricultural demand. To secure long-term water security, the country is increasingly turning to advanced technologies. Among these, desalination is emerging as a cornerstone of sustainable water management, offering a reliable solution to supplement limited freshwater resources.
What is the Water Desalination Process?
What is the water desalination process? It is the method of removing dissolved salts, minerals, and impurities from seawater or brackish water to make it suitable for human consumption and industrial use. Modern desalination relies largely on reverse osmosis membranes, which force water through a semi-permeable barrier, separating pure water molecules from salts and contaminants.
This makes desalination a dependable method of producing clean drinking water even when rainfall is scarce or traditional freshwater reserves are strained.
The Role of Desalination Plants in Portugal
Building and operating advanced desalination plants offers Portugal multiple advantages:
- Reliable Supply – Seawater is abundant, and desalination ensures steady water availability regardless of climate conditions.
- Support for Agriculture – By providing irrigation water, desalination helps sustain Portugal’s vital agricultural exports.
- Urban Growth – Growing cities and tourist regions require consistent supplies of safe drinking water, even during dry summers.
- Resilience to Climate Change – As droughts become more frequent, desalination ensures security against water shortages.
In coastal regions such as the Algarve, desalination plants are already being considered as critical infrastructure to meet rising demand.
Water Purification and Desalination – Beyond Drinking Water
While desalination is best known for providing potable water, it also supports water purification and desalination in industries. From food processing and pharmaceuticals to power generation, purified water is essential for quality, safety, and compliance. Desalination plants can supply industrial-grade water, reducing pressure on freshwater resources.
