Restore magnesium, balance sulfate, improve purified water
Magnesium Sulphate Heptahydrate is used in post-RO remineralization to return essential magnesium and sulfate ions to treated water. In bottled water and beverage production, it helps correct the flat sensory profile created by aggressive purification while supporting a cleaner, more balanced taste and a more complete mineral composition.
What this product helps you achieve
Magnesium restoration – returns Mg to purified water after reverse osmosis or membrane treatment.
Taste improvement – helps reduce the flat, empty character of demineralized water and supports a fresher, more balanced finish.
Reliable remineralization – dissolves efficiently for controlled use in production dosing systems.
Used correctly, Magnesium Sulphate Heptahydrate helps turn highly purified water into a more balanced, functional, and market-ready finished product
