Segmentation

Analysis by Membrane

By membrane, the solar-powered desalination plants market is divided into reverse osmosis, electro-dialysis and electro-dialysis reversal, membrane distillation, nanofiltration, and others.

Reverse osmosis (RO) is the most commonly used method, which uses semi-permeable membranes to remove salts and contaminants from seawater or saltwater. Electrodialysis (ED) and electro-dialysis reversal (EDR) make electrically charged membranes to separate ions, making them suitable for moderate saltwater sources. These technologies provide high recovery rate and are especially effective in the treatment of salt water. The segment may lead the market.

Other membrane-based techniques include membrane distillation (MDs), which benefit from the temperature difference to drive water vapor through a membrane, and nano filtration (NF), which removes small particles while maintaining the essential minerals. Each of these methods has its benefits, where the quality of the water source depends on factors such as energy availability and cost ideas. Increasing demand for effective and durable uninterrupted solutions develops in these membrane technologies.

Analysis by Desalination Method
