The main problem of desalinated water concerns the quality of the water and its production process. Here are some of the main problems:
-
Chemical composition and mineral content : the desalination process removes not only the salts from the water but also the essential minerals present in it, such as magnesium, calcium and potassium. Desalinated water is usually very low in minerals, which can affect human health, especially when it comes to drinking water.
-
The acidity of the water : desalinated water is more acidic (has a lower pH) compared to natural water. Increased acidity can damage pipes and affect the taste of water.
-
Environmental impact : The desalination process is energy-intensive, and produces a lot of salty waste that is discharged back into the sea, which may harm the marine environment and the ecosystems in the seas.
-
High cost : water desalination requires complex and expensive technology, which leads to high costs. In many countries, desalination costs are added to residents' water bills.
-
Lack of sustainability : Dependence on desalinated water may lead to lack of sustainability if the methods for using this water do not include consideration of the environment and the preservation of natural water sources.
While desalinated water is an important solution for water supply in dry areas like Israel, it is necessary to continue to improve the existing processes and find ways to minimize the negative effects on the environment and health.
