NINGBO INNO PHARMCHEM CO.,LTD. supplies both Ferrous Sulfate (CAS 7720-78-7) and various forms of Ferric Sulfate, both of which are crucial inorganic coagulants in water treatment. While both are iron-based salts used to purify water, their chemical states and consequently their performance characteristics differ significantly. Understanding these differences is key to selecting the most effective product for specific water treatment challenges.

Ferrous Sulfate contains iron in its +2 oxidation state (Fe2+), commonly appearing as blue-green crystals or a yellow viscous liquid (if oxidized). It is often used for its ability to reduce chromate, complex cyanide, and control hydrogen sulfide odor. In water treatment, Ferrous Sulfate acts as a coagulant and flocculant, aiding in the removal of suspended solids and phosphates. Its effectiveness can be influenced by pH, and it may require oxidation to the more active ferric state for optimal performance in certain applications.

Ferric Sulfate, on the other hand, contains iron in its +3 oxidation state (Fe3+). It is typically supplied as a dark brown or yellow liquid solution. Ferric Sulfate is generally considered a more potent coagulant than Ferrous Sulfate, especially at neutral to alkaline pH levels. It excels at removing turbidity, color, and phosphates from raw water and wastewater. Its higher charge density allows it to destabilize colloidal particles more effectively, leading to faster and more efficient floc formation.

The choice between Ferrous Sulfate and Ferric Sulfate often depends on the specific water chemistry, including pH, alkalinity, and the nature of contaminants present. For applications requiring odor control or chromate reduction, Ferrous Sulfate might be preferred. However, for general turbidity removal and phosphate precipitation across a broader pH range, Ferric Sulfate is often the more powerful choice. NINGBO INNO PHARMCHEM CO.,LTD. offers both types of iron salts, allowing clients to select based on detailed water analysis and treatment goals.

Both compounds are vital for effective water management, and sourcing them from a reputable supplier like NINGBO INNO PHARMCHEM CO.,LTD. ensures product quality and consistency. The price of Ferrous Sulfate and Ferric Sulfate can vary based on market conditions and product specifications, but their proven efficacy makes them invaluable tools in ensuring clean and safe water resources. Professionals in the water treatment industry rely on the distinct advantages of each iron salt to meet diverse treatment objectives.
