Basic introduction of liquid polyferric sulfate

Liquid polyferric sulfate is a chemical substance, reddish brown liquid, no precipitation. It is widely used in the purification treatment of drinking water, industrial water, various industrial wastewater, urban sewage, sludge dewatering, etc.

Product Name: Liquid Polymeric Ferric Sulfate
Executive standard: GB14591-2006
Appearance: reddish brown liquid, no precipitation

Application Features
Compared with other inorganic flocculants, polyferric sulfate has the following characteristics:
1. New, high-quality, high-efficiency iron salt inorganic polymer flocculant;
2. Excellent coagulation performance, dense alum blossoms and fast settling speed;
3. Excellent water purification effect, good water quality, no harmful substances such as aluminum, chlorine and heavy metal ions, and no water phase transfer of iron ions, non-toxic, harmless, safe and reliable;
4. It has significant effects in removing turbidity, decolorization, deoiling, dehydration, sterilization, deodorization, algae removal, and removal of COD, BOD and heavy metal ions in water;
5. It is suitable for a wide range of water body pH value of 4-11, and the best pH value range is 6-9. After purification, the pH value and total alkalinity of the raw water change slightly, and it is less corrosive to the treatment equipment;
6. It has a significant effect on the purification treatment of micro-polluted, algae-containing, low-temperature and low-turbidity raw water, especially for high-turbidity raw water;
7. The dosage is small, the cost is low, and the processing cost can be saved by 20%-50%.
Purification of Domestic Wastewater by Liquid Polyferric Sulfate

Purification mechanism:
1. Inorganic matter removal mechanism: large suspensions are easy to precipitate, can remove 40-50% of inorganic colloids stably, and can be entrained and settled by the active method with good cohesion, and separated from water. Some inorganic particles do not exist independently. They form suspended solids and colloids with organic matter, which rise together with the biogas bubbles and generate bubbles. Then the organic matter is degraded, separated from the bubbles and sinks, and finally removed by sludge.
2. Removal mechanism of parasite eggs and germs: Free ammonia can be produced by biological fermentation and decomposition of organic matter, which can penetrate into eggs and cell membranes, and has the effect of killing eggs and sterilizing. Secondly, the anaerobic environment also prevents aerobic disease from growing, some reduce or lose the ability to cause disease, and some die quickly. Practice shows that 50% of the scum on roundworm eggs in the biogas digester, more than 40% sink to the bottom of the tank, less than 10% in the fermentation broth, and the effluent removal rate is more than 95%, and the Escherichia coli value drops from to.
3. Mechanism of anaerobic digestion of sewage

The liquid polymeric ferric sulfate reaction process consists of the following three stages:
1. Hydrolysis stage: Under the action of hydrolysis and fermentation bacteria, macromolecular substances such as carbohydrates, proteins and fats are hydrolyzed and fermented into small molecular substances such as monosaccharides, amino acids, fatty acids, glycerol and carbon dioxide, etc., and solid substances are hydrolyzed to soluble substance.
2. Acidification stage: Under the action of hydrogen-producing acetogenic bacteria, the products of the first stage are converted into hydrogen, carbon dioxide and acetic acid.
3. Methane-producing Attachment: Through the action of two groups of physiologically different alkyl-producing bacteria, the mismatched hydrogen and carbon dioxide are converted into methane.
Scope of application
Widely used in the purification treatment of urban drinking water, industrial circulating water, industrial wastewater and urban life in chemical, petroleum, mining, papermaking, printing and dyeing, brewing, steel, coal gas, paint, leather, pharmaceutical, food, electroplating and other industries Sewage purification and sludge dehydration treatment.

product instructions
1. The dosage can be determined according to the different turbidity of the raw water to determine the best dosage. For general turbidity (turbidity of 100-500mg/L) water, use 30-50 kg of this product per thousand tons, non-drinking water with high turbidity industrial wastewater Appropriate dosage can be used.
2. When treating industrial wastewater, dilute the first-class polymer ferric sulfate to an aqueous solution that is 1-2 times. When the source water concentration is high and the treated water volume is large, it can be directly added. Then, according to the results of the laboratory simulation test, dosing according to the best process conditions and dosage, after full stirring, coagulation and sedimentation, clear effluent can be obtained.
3. The water purification plant can also be added after diluting 2-5 times. The dosage is determined according to the nature of the raw water through production debugging or beaker experiment depending on the proper amount of alum formation. The water plant can use other medicine dosages as a reference. Under the same conditions, the dosage of this product and solid polyaluminum chloride It is roughly equivalent, 1/2-1/3 of the amount of solid aluminum sulfate. If the original liquid product is used, it can be determined according to the concentration of the corresponding agent, which is roughly determined by the weight ratio of 1:3.
