Our hexahydrate grade consists of well-formed crystalline lumps with tightly controlled water of crystallisation. This form dissolves predictably in aqueous systems, giving operators precise control over dosing in treatment processes. It is particularly valued in applications where gradual dissolution and measured release of ferric ions are advantageous.

The hexahydrate form is selected where controlled dissolution and lower handling hazard compared to anhydrous grades offer operational advantages.
Highly effective at precipitating phosphorus and coagulating organic matter in municipal sewage systems. The crystalline form allows straightforward volumetric measurement for consistent dosing across varying flow rates.
Used as a starting material in the manufacture of iron-based pigments. The controlled purity of our hexahydrate ensures colour consistency and minimises unwanted side reactions during pigment synthesis.
Serves as a reagent and catalyst in certain pharmaceutical intermediate preparations. The low ferrous content and controlled impurity profile make it suitable for processes requiring high chemical selectivity.
Performs as an efficient coagulant for turbidity reduction, colour removal, and heavy metal capture in both potable water treatment facilities and industrial cooling systems.
