Polyferric sulfate

Polyferric sulfate is widely used in the purification treatment of domestic drinking water, industrial circulating water, and industrial wastewater from industries such as chemical, petroleum, mining, papermaking, printing and dyeing, brewing, steel, and gas. It achieves ideal results for various types of water sources in different regions. Polyferric sulfate manufacturer price, wastewater treatment coagulant polyferric sulfate.

Polyferric sulfate is a new, high-quality, and efficient inorganic polymer coagulant of the iron salt type. It is mainly used for water purification with excellent effects, good water quality, and does not contain harmful substances such as aluminum, chlorine, and heavy metal ions. It also does not cause the transfer of iron ions into water, making it non-toxic, harmless, and safe. It has significant effects in removing turbidity, decolorization, deoiling, dehydration, sterilization, deodorization, algae removal, and the elimination of COD, BOD, and heavy metal ions from water.

Polyferric sulfate is widely used in the purification treatment of drinking water, industrial water, various industrial wastewaters, urban sewage, and sludge dewatering, such as printing and dyeing wastewater. It also has extensive applications in foundry, papermaking, medicine, and tanning industries.River wastewater treatment methods include physical, chemical, biochemical, and membrane treatment. Chemical wastewater treatment methods include oxidation-reduction, neutralization, chemical precipitation, adsorption, and ion exchange. Chemical precipitation is widely used in wastewater treatment, primarily by adding chemical coagulants to wastewater to chemically convert dissolved substances into water-insoluble substances, which are then further separated through sedimentation. Polyferric sulfate is a typical high-efficiency chemical coagulant widely used in wastewater treatment.

Role of Polyferric Sulfate in River Treatment

By adding an appropriate amount of PFS to sludge, the colloidal surface charge or structure of suspended sludge particles is altered, reducing the repulsive force between colloidal particles and destabilizing them, allowing sludge particles to flocculate and settle. Simultaneously, the surface area of the colloid decreases as the volume of sludge flocs increases, weakening the adsorption between flocs and water, significantly improving dewatering performance.********Why Does the Effectiveness of Polyferric Sulfate Decrease********

Why does the same product from the same manufacturer result in reduced effectiveness and insufficient polymerization after water treatment with polyferric sulfate?
Why does the effectiveness of polyferric sulfate decrease?
1. Quality issues with this batch, such as insufficient raw materials or catalysts during production, incomplete catalysis, failing to achieve the original polymerization effect, etc.

2. Expired: The product has been stored for too long, exceeding its stable storage period. Or improper storage conditions have caused the product to deteriorate and lose quality.

3. Incorrect pH value: Water is too acidic. Any solution inevitably involves pH, and incorrect pH control will inevitably affect the effectiveness of polyferric sulfate.

4. Temperature too low: Polymerization occurs faster at high temperatures and slower at low temperatures, but this does not mean high temperatures are always effective. Excessively high temperatures can cause certain reaction conditions to fail. Only the appropriate temperature is favorable for the reaction.

5. Incorrect material conditions: Many substances are not pure and contain too many impurities, which can slow down the reaction rate or even halt polymerization. The phenomenon of polyferric sulfate failing to polymerize is mainly caused by factors such as long storage time, low temperature, and improper raw material conditions.
