What is the dosage of ferric sulfate
 

Ferric sulfate is mainly used in sewage treatment, as a water purification flocculant has been concerned, then, its dosage is also many customers want to know.

 

 Polyferric sulfate
 

General industry, Amount of ferric sulfate 15-50 kg of solid products are used per thousand tons of water. However, according to the nature of the sewage, the amount used will also change, such as raw water quality, temperature, salinity, pH value, impurities in water, etc.
 

The amount of ferric sulfate is affected by temperature: with the increase of water temperature, the dissolution rate of ferric sulfate is accelerated. When the ferric sulfate solution is saturated at about 30 ℃. Of course, the effect of condensation temperature on the polymerization performance will continue to be affected when the salinity increases.
 

The dosage of ferric sulfate is affected by alkali: the concentration of ferric ion is higher than 10% - 20%. The higher the reaction concentration, the faster the solidification reaction speed.
 

   Amount of ferric sulfate Affected by H value: the application range of ferric sulfate is very wide, and the range of H value 6-9 is applicable.
 

Of course, when users use ferric sulfate products, excessive addition will waste resources, the cost of water treatment will increase, and the water quality may deteriorate, such as turbidity, chroma, pH, COD, SS and other indicators exceed the standard, facing environmental risks. If the dosage is too small, the desired effect can not be achieved. In addition, excessive dose will cause certain damage to equipment, corrosion equipment, pipelines, etc. Therefore, in the use of PFS, we must do a good job in water quality sampling, testing and dose calculation in advance, and use ferric sulfate reasonably, so as to achieve good results.
 

Therefore, when using ferric sulfate products, we need to have a certain understanding of the sewage, carry out a small test according to the nature of the sewage, and then determine Amount of ferric sulfate
