Polyferric sulfate is a kind of coagulant with superior performance. The common polyferric sulfate in the market includes solid polyferric sulfate and liquid polyferric sulfate. For liquid polyferric sulfate, filter source company reminds you to pay attention to the following situations in the process of transportation and use.

 

Polymerized ferric sulfate in production will go through oxidation, hydrolysis, polymerization and other reaction processes, and the three reactions are carried out at the same time. With the release of heat in the reaction process, the semi-finished polymerized ferric sulfate will be in a high temperature condition. Therefore, it is necessary to cool the liquid polymerized ferric sulfate to prevent further reaction. If polymerized ferric sulfate at high temperature is loaded and transported, the polymerized ferric sulfate will continue to react and intensify the hydrolysis reaction. It will easily produce strong iron oxide gel and affect the use of polymeric ferric sulfate. Therefore, PFS liquid should be loaded at room temperature, and the tanker and barrel should be cleaned before storage and transportation.

 

When PFS is used, the dosage and pH value of wastewater to be treated have great influence on the effect. Therefore, the small-scale test of PFS must be carried out. According to the analysis of the small-scale test process and the treatment effect, the suitable dosage and pH value of PFS are obtained. The liquid PFS can be diluted in a certain proportion before use, while the solid PFS needs to be dissolved first and then diluted with water.
