Detailed explanation of water purification principle of polyferric sulfate

Detailed explanation of the principle of ferric sulfate in water purification
 

Polyferric sulfate is a commonly used flocculant for water purification in iron salts, and its water purification principle is also based on scientific basis. Please see Henan Zhengyuan's solution for you:
 

The formula of PFS water purification principle is: Fe3 + + 3OH - = Fe (OH) 3 ferric ions hydrolyze to form flocculent iron hydroxide precipitation, which can precipitate suspended solids in water and achieve the purpose of water purification.
 

As an inorganic polymer flocculant, PFS can be divided into solid PFS and liquid PFS. PFS is a reddish brown viscous liquid; PFS is a red or light yellow granular substance easily soluble in water.
 

 Polyferric sulfate
 

   Water purification principle of polyferric sulfate A large amount of [FE4 (H2O) 6], [Fe2 (H2O) 6] and [Fe] are produced after the hydrolysis of PFS (OH) 2] and other polynuclear complexes can coagulate the colloidal particles in water together through adsorption, bridging and cross-linking. At the same time, a series of physical and chemical changes have taken place, which makes them have strong electric neutralization ability, thus reducing the potential of micelles, breaking the disorder of micelles, and promoting the rapid coagulation and precipitation of colloidal particles.
 

The characteristics of PFS are: excellent coagulation performance, dense alum, fast settling speed, stable performance, excellent water purification effect, with significant decolorization, deodorization, dehydration, deoiling, sterilization, removal of heavy metal ions in water, ammonia nitrogen, strict nitrate nitrogen, silica sol, radioactive substances and carcinogens, etc., with low dosage and low cost.
 

The above is Zhengyuan water purification for you to share Water purification principle of polyferric sulfate I hope to help you!
