Polyferric sulfate as a water purification agent, in order to achieve the desired effect, we need to have the correct use method. So how to determine the use of PFS? Laboratory test is one of the very good methods, and it is also a step that most water purification agents need to carry out before using.

How to carry out the pilot test of PFS? First of all, we need to obtain a certain amount of sewage, and then test the pH value of the sewage. Because the effect of PFS is generally better in slight alkalinity, it is necessary to adjust the pH value of sewage to weak alkalinity through acid-base additives. Then we need to dissolve PFS with water to form a 5% aqueous solution. Through the syringe, extract different amounts of polymeric ferric sulfate solution, and then divide the sewage into several equal parts. After adding different amounts of polymeric ferric sulfate solution, slowly stir, observe the effect of alum formation in the sewage, and record it.

Through small-scale test, the actual dosage, correct use method and other matters needing attention can be determined. In particular, the dosage of PFS directly affects the effect of wastewater treatment.

In practice, the use of PFS also needs to be changed according to the different dissolution and dosing methods, especially in the aspect of dosing agent, it also needs to be changed according to the sewage treatment process.
