Detailed description of polymeric ferric sulphate for power plants: Polyferric sulphate for power plants can be adapted to different sewage water conditions. Various wastewaters, organic, inorganic, sewage, and complex sewage treatments in wastewater systems with variable pH changes. The technical advantages and economic advantages solve the shortcomings of large consumption and dehydration of industrial wastewater and small domestic sewage treatment plants, which reduces the large demand and operating cost of the enterprise, electroplating wastewater treatment, electroplating wastewater treatment and reuse of flocculant It is the most cost-effective, most potential, and highly applicable sewage treatment flocculant.
The polyferric sulfate used in power plants is an intermediate product in the process of hydrolysis and coagulation. It can exert the charge in the bridge by the polymerization cation. The water treatment of the ferric sulfate manufacturer produces a medium content of polyferric sulfate. It is widely used in drinking water. , industrial water, various industrial wastewater, urban sewage, sludge dewatering and other purification treatment.
Water treatment of polymeric ferric sulfate has the following characteristics:
1.New, high-quality, high-efficiency iron salt inorganic polymer flocculant;
2.Excellent coagulation performance, compacted silk flower and fast sedimentation speed;
3.The water purification effect is excellent, the water quality is good, does not contain harmful substances such as aluminum, chlorine and heavy metal ions, and also has no iron ion aqueous phase transfer, non-toxic, harmless, safe and reliable;
4.In addition to turbidity, decolorization, deoiling, dehydration, sterilization, deodorization, algae removal, removal of COD, BOD and heavy metal ions in water, etc.;
5.The pH range of the water body is 4-11, and the optimum range is 6-9. The pH value and total alkalinity of the raw water after purification are small, and the corrosion of the processing equipment is small;
6.It has remarkable effects on micro-pollution, algae-containing, low-temperature and low-turbidity raw water purification, and is especially effective for high turbidity raw water purification;
7.The dosage is low, the cost is low, and the processing cost can be saved by 20%-50%.
Due to the different nature of raw water, it should be commissioned or beaker tested according to different situations to obtain the best conditions of use and the best dosage to achieve the best results:
1.Before use, the polyferric sulfate is put into the solvent pool at a certain concentration (10-30%), stirred by tap water to make it fully hydrolyzed, left to a reddish brown liquid, and then diluted with water to the desired concentration. The condensate. The water plant can also be directly dosed with 2-5%, and the industrial wastewater treatment is directly formulated into 5-10%.
2.The determination of dosage, according to the nature of raw water can be determined by production commissioning or beaker experiment depending on the amount of sputum flower formation, the water plant can use the other amount of the original as a reference, under the same conditions, the product and solid polymerization chlorination The amount of aluminum is roughly equivalent, which is 1/3-1/4 of the amount of solid aluminum sulfate. If the original product is a liquid product, it can be calculated according to the concentration of the corresponding agent. It is roughly determined by the weight ratio of 1:3.
3.When using, pump the above prepared liquid into the metering tank, and coagulate with the raw water by metering and adding the liquid.
4.Under normal circumstances, the day of preparation on the same day, dispensing requires tap water, a little sediment is a normal phenomenon.
5.Pay attention to the hydraulic conditions of the three stages of the coagulation process and the formation of silk flower conditions.
