Polymeric ferric sulfate manufacturers: to introduce you to the use of polymeric ferric sulfate precautions
Usepolymeric ferric sulfateWhat should be paid attention to? Usepolymeric ferric sulfateNote:
1. Before use, willpolymeric ferric sulfateTo a certain concentration (10-30%) into the dissolved alum pool, pour into the tap water and stirring to make it completely hydrolyzed, standing until the red brown liquid, and then diluted with water to reach the required concentration and add coagulant. It is also possible to combine the water plant with 2% to 5% liquid.polymeric ferric sulfateDirect addition, industrial wastewater treatment can be directly prepared with 5-10% addition.
2. Determine the dose according to the nature of the raw water. The dose can be determined according to the amount of alum formed through production debugging or burnout experiments. Water plants can use other drug doses as a reference. Under the same conditions, the dosage of this product and solid polymerized alumina is slightly lower, which is 1/3-1/4 of the dosage of solid aluminum sulfate. If the original liquid product is used, it can be calculated based on the corresponding reagent concentration.
3. When in use, the liquid medicine prepared above is pumped into the metering tank, and the raw water is condensed by metering the liquid medicine. Usually, it is used on the preparation day. Tap water is required for distribution, and a small amount of precipitation is normal.
polymeric ferric sulfateThe use of the three stages of the coagulation process involves attention to hydraulic conditions and alum formation.
