Solid polyferric sulfate

Polyferric sulfate is a kind of inorganic polymer coagulant with superior performance. Its morphological character is light yellow amorphous powder solid, which is easily soluble in water. Polyferric sulfate is widely used in the purification of drinking water, industrial water, various industrial wastewater, urban sewage, sludge dewatering, etc.

Characteristics of solid polymerized ferric sulfate

1. New type, high quality and high efficiency inorganic polymer flocculant of iron salts;

2. Excellent coagulation performance, dense alum and fast settling speed;

It is also harmless to heavy metal ions and aluminum ions, and has no harmful effect on water;

4. Turbidity removal, decolorization, deoiling, dehydration, bacteria removal, deodorization, algae removal, COD, BOD and heavy metal ions in water are significant;

5. The pH range of the water body is 4-11, and the range of pH value is 6-9. After purification, the pH value and total alkalinity of raw water change little, and the corrosion to the treatment equipment is small;

6. It has obvious effect on micro polluted, algae containing, low temperature and low turbidity raw water, especially for high turbidity raw water;

The treatment cost can be saved by 20% - 50%.
 

Synthesis of solid polymerized ferric sulfate

The manufacturing methods of PFS solid products are as follows: 1. Liquid ferrous sulfate is used as raw material and Shengsheng air is used as oxidant. After low temperature dehydration, grinding, high temperature oxidation, xinxinran cooling, polymerization adjustment, solidification, aging and crushing, the finished product is finished.
 

Application of solid polymerized ferric sulfate

When using, the solid polyferric sulfate is mixed into 10% - 30% aqueous solution, and then according to the specific situation, the prepared solution is put in according to the best conditions and dosage, and good coagulation effect can be obtained after full stirring.

The dosage can be determined according to the different turbidity of raw water. For general turbid water (turbidity is 100-500mg / L), 30-50kg of this product can be used per thousand tons. For non drinking water, high turbidity industrial sewage can be properly added.
 

Precautions for use

1. Before use, solid polyferric sulfate is put into the alum dissolving tank according to a certain concentration (10-30%). Tap water is injected to make it fully hydrolyzed, and then it is left to be a reddish brown liquid, then diluted with water to the required concentration and added with coagulation. Water plants can also be mixed into 2-5% direct dosing, and industrial wastewater treatment can be directly mixed into 5-10% dosing.

2. According to the nature of raw water, it can be determined by production commissioning or beaker test depending on the amount of alum formation. The water treatment plant can use the original dosage of other chemicals as reference. Under the same conditions, the consumption of this product is roughly equivalent to that of solid polyaluminum chloride, which is 1 / 3-1 / 4 of that of solid aluminum sulfate. If the original liquid product is used, it can be calculated and determined according to the corresponding reagent concentration. It is roughly determined by the weight ratio of 1:3.

3. When in use, the prepared liquid medicine is pumped into the metering tank and coagulated with raw water through metering.

In general, it is necessary to use tap water for dispensing on the same day. It is normal to have a little sediment.
 

Precautions for storage of solid polyferric sulfate:

Store in cool, dry and well ventilated warehouse. Keep away from fire and heat sources. The relative humidity was kept below 75%. The package must be sealed and protected from dampness.

It should be stored separately from inflammable (combustible), alkali, alcohol, etc., and should not be mixed storage. It should not be stored for a long time to avoid deterioration. The storage area should be equipped with suitable materials to contain the leakage.
