Application of Reverse Osmosis Membrane in Brackish Water Desalination

What is Brackish Water?

Brackish water is defined as poor-quality water with mineralization greater than 1000mg/L. It is not suitable for direct use and usually contains high concentrations of soluble solids, fluoride, heavy metal ions, and other contaminants.

What Are the Hazards of Long-Term Consumption of Brackish Water?

Studies have shown that long-term consumption of brackish water can cause significant harm to human bones, skin, stomach, and intestines. Even using brackish water for irrigation can have detrimental effects. It can damage the soil, leading to abnormal crop growth, yellowing, leaf loss, or even withering.
