What is the difference between the liquid and solid of PFS

At present, there are both liquid and solid polyferric sulfate in the market. However, because solid polyferric sulfate has more advantages in packaging, transportation and preservation, common polyferric sulfate is in the form of solid. However, some manufacturers still need to buy liquid polyferric sulfate for the needs of treatment process and equipment, compared with solid polyferric sulfate, The price of liquid polyferric sulfate is very cheap, which is one of the reasons why manufacturers have been using it.
The basicity of liquid PFS is generally between 10% and 13%. The flocculation of PFS in water will produce more alum, and the precipitation efficiency is also very high, especially when adding other water purification coagulant aids, such as polyacrylamide.
Compared with the solid polyferric sulfate, it must be dissolved before use. In some cases with poor dissolution conditions, the dissolution speed of polyferric sulfate is slow, and the use effect cannot be guaranteed when the dissolution is incomplete. When the liquid PFS is used in water purification, it does not need to be dissolved, so the hydrolysis speed is faster when diluted with water. After being added to the sewage, the reaction is rapid and the effect is good. Especially in the aspect of sewage phosphorus removal, it is often used as sewage phosphorus removal agent.
Different PFS have different advantages. When we buy PFS, we need to choose solid or liquid according to our own needs.
