The advantages of our ferrous sulphate:

- High iron content and purity: a minimum Fe²⁺ content of 19% gives better coagulation efficiency.
- Low levels of heavy metals and contaminants, so treated water stays safe.
- Good solubility and dissolution rate thanks to a proper crystal structure.
- Uniform particle size improves dosing accuracy and mixing.
- Lower impurities, for example manganese, aluminium and chromium.
