PDV salt (pure dried vacuum salt), also known as sodium chloride, is a high-purity salt widely used in water treatment, food processing, and industrial manufacturing applications. Typically supplied as fine white crystals, PDV salt is valued for its exceptional purity, consistent quality, and excellent solubility. Its reliable performance makes it particularly suitable for water softening systems, chemical production, and specialist processing environments. Sodium chloride is also one of the most versatile industrial chemicals, playing an essential role in countless commercial and manufacturing processes.
