A brackish water is a type of water that has a higher concentration of dissolved salts than fresh water, but lower than seawater.
It is found in many coastal regions and estuaries, where fresh water mixes with seawater.

Characteristics of brackish water:

• Moderate salinity: Brackish water contains between 0.5 and 30 grams of salt per liter.
• Limited use: Not suitable for direct consumption due to its salinity.

Challenges and treatment: The use of brackish water for human consumption and other purposes requires specific treatments to remove salts and other contaminants.

Reverse osmosis for brackish water: Reverse osmosis is an effective technology for desalinating brackish water, making it potable and suitable for various applications.
Este processo envolve a passagem da água através de uma membrana semipermeável, que retém os sais e outras impurezas.
