At Navkar Group, we specialize in producing Low Hardness Salt with controlled calcium and magnesium levels, ensuring exceptional purity and consistent performance. Our range includes Below 150 PPM, 100 PPM, and 50 PPM hardness salts, precisely processed to meet the demanding requirements of industrial and food applications.
This salt is manufactured through advanced refining and washing techniques that reduce hardness-causing minerals without compromising the natural chemical balance of the salt crystals.
Our Low Hardness Salt is ideal for a wide range of industrial and process applications:
Water treatment and softening systems
Detergent and chemical manufacturing
Textile dyeing and finishing processes
Food processing where controlled hardness is critical
Pharmaceutical and laboratory applications requiring high-purity salt.
