Polymeric ferric sulfate performance characteristics
The polymerized ferric sulfate has stable performance, excellent water purification effect, no harmful substances such as heavy metal ions, and has various functions such as decolorization, deodorization, deoiling, sterilization, removal of heavy metal ions in water, radioactive substances and carcinogens, etc., for COD, BOD And the removal rate of chromaticity is as high as 90% or more; it has a good effect on the purification of low temperature, low turbidity and high turbidity raw water. It is easy to use, low in cost, and the processing cost is generally 20%-50% compared with other inorganic flocculants.
Use method and precautions of polyferric sulfate
1. Before using the ferric sulfate, a certain concentration (10%-30%) of the product should be put into the solvent pool, and the tap water should be injected, and fully hydrolyzed under stirring, and left to stand for about 2 hours until it is reddish brown and transparent. Use, usually formulated on the same day, used on the same day.
2. When the polyferric sulfate is used, the chemical solution is metered out according to the conditions, and the tap water is mixed and diluted to about 1%. The inflow into the coagulation tank and the raw water rapidly condense (stage) to form fine squid, and the stalk grows thick and thick, about 20 Minutes flow into the sedimentation tank, and the water gradually gradually settles (stage), and the water body gradually becomes clear, and then enters the filter through the water outlet.
3. The applicable pH range of polymeric ferric sulfate is 5-11, and the best range is 6-9. According to the nature of different raw water, first adjust the range of PH value.
4. Polyferric sulfate should be stored in a dry, heat-proof (below 80 ° C), must be dissolved before use, dissolution equipment and dosing equipment should use corrosion-resistant materials.
Polyferric sulfate application range
Widely used in the purification of drinking water, urban sewage, sludge dehydration, industrial water, various industrial wastewater. It belongs to a new type of high-efficiency inorganic polymer iron salt flocculant, which is dense in flowering and quick in sedimentation; it has good water purification effect, compared with water purification products such as ferrous sulfate and polyaluminium chloride, especially for drinking water, Henan Polyferric Sulfate, Henan Iron sulphate water purification performance is better, does not contain harmful substances such as aluminum, chlorine and heavy metal ions, can be described as harmless, safe and reliable high-efficiency water treatment agent. In the process of water treatment, the coagulation effect is good, the consumption is small, the sedimentation speed is fast, and it has significant effects such as decolorization, deoiling, sterilization, removal of heavy metal ions in water, radioactive substances and carcinogens, etc., for COD, BOD and The removal rate of chromaticity is as high as 90%; the pH value of water is 4-11, the pH value of water after purification is small, the corrosion of treatment equipment is small, the water purification effect is excellent, and the effluent quality is good. Contains harmful substances such as aluminum, chlorine and heavy metal ions. The quality of the products conforms to the national standards of the People's Republic of China.
