Our Earth is covered in water, but only a mere 1% of it is freshwater. As our global population grows, the competition for this limited potable water resource becomes increasingly fierce. Brackish water reverse osmosis treatment emerges as a vital solution in the quest for sustainable alternatives.

What is Brackish Water?

Brackish water is a blend of freshwater and seawater characterized by a spectrum of salinity. It exists naturally and as a consequence of human activities. Its distinct properties make it an intriguing subject of study in water resources management and treatment.

Where Does It Come From?

The primary source of brackish water is estuaries, where rivers meet with the vast ocean. Here, the mingling of freshwater and saltwater creates a transitional zone with varying salinity levels. However, brackish water is not confined to estuaries alone. It also sits beneath the Earth’s surface, hidden within fossil aquifers and wells. In these underground reservoirs, minerals from the surrounding geology, particularly sodium and chloride components from salt deposits, slowly infiltrate the stored water, transforming it into brackish water over time. Furthermore, human activities, such as freshwater prawn farming and the innovative salinity gradient energy (SGE) processes, contribute to the creation of brackish water as a by-product.

Reverse Osmosis Brackish Water Treatment

Brackish water usually has a total dissolved solids (TDS) concentration between 1,000 and 10,000 parts per million (ppm). Reverse osmosis (RO) works by applying pressure to push the feedwater through a specialized filtering membrane. This membrane acts as a selective barrier, allowing only water molecules to pass through while obstructing salts, contaminants, minerals, and impurities. The result is the production of ultrapure freshwater.

Brackish water RO requires more than 200 psi to push the water through the membrane. The high osmotic pressure necessitates more energy and premium equipment that can withstand higher pressures than a standard RO system. Seawater RO systems, used to desalinate ocean water, require even higher pressures and energy input, making brackish water more accessible and energy-efficient.

Why Does It Matter?

Desalination processes open a new world of opportunity for water that would typically be considered impure. The applications of industrial brackish water reverse osmosis span from agriculture and aquaculture to medicinal and pharmaceutical uses. By transforming saline water into a valuable resource, water treatment ensures a reliable water supply. It contributes to environmental conservation efforts by decreasing the demand for scarce freshwater and preserving freshwater ecosystems.
