Although the TDS remained over the WHO potable water regular, the output is suited to irrigation and livestock watering. These outcomes spotlight the File/M desalination process’s potential to deal with water scarcity and cooling demands in source-minimal, off-grid locations, contributing to sustainable desalination technologies run by renewable Strength.
