For many newcomers, it seems difficult to distinguish between these two kinds of medicine. In fact, PAM is an organic high molecular compound, its name is polyacrylamide, and its average molecular weight can range from thousands to tens of millions. PAC is an inorganic substance called polyaluminum chloride.
PAC is different from PAM in the following aspects
1. Different flocculation mechanism
The reason why PAC can flocculate is that it will form a network structure after entering the water, which will hold small solid particles together. PAM can flocculate because it can break the electric balance between the small particles and make the solid particles in the wastewater gather together.
2. Different colors
PAC is generally white, yellowish brown and yellow. PAM is only white powder.
3. Different dosage
The dosage of PAC is generally 200-300 ppm, that is, 200-300 mg per liter of wastewater. The dosage of PAM is generally 3-10ppm, about 3-10mg per liter of wastewater. Ppm represents the PPM, 1ppm = 0.001%, generally used at low concentration.
In wastewater treatment, inorganic flocculant and organic polymer flocculant (such as polyacrylamide) are usually added at the same time. The purpose is to improve the flocculation effect and reduce the dosage of agent. Then, if it is two kinds of inorganic polymer flocculants, can PFS and PACl be used together?
In wastewater treatment, the mechanism of the two is basically the same. When used as coagulant, polyferric and polyaluminum can be added to the wastewater. There is no difference in the order of adding the two, both of them can play the role of coagulation, and their effect is basically unchanged.
1. The basicity of PFS is lower than that of PFS. Neutralization reaction will occur when PFS and PFS are mixed, which leads to the shift of hydrolysis equilibrium. Finally, most of the aluminum and iron are hydrolyzed to form hydroxide colloid, which is jelly like. Part of the non hydrolytic will also depolymerize, metal salts form ionic form, which has lost the original polymerization and can not continue to hydrolyze in wastewater to produce coagulation effect.
2. In addition, the change of basicity will also affect the coagulation effect, and the formation of hydroxide colloid of aluminum and iron will affect the coagulation effect.
3. From the point of view of transportation, the two cannot be mixed, and the price of purchasing two different products at the same time will be higher than that of purchasing the same product.
Therefore, in practical application, either polyaluminum chloride or polyferric sulfate are added. Generally, they are not used at the same time. Even if they are used, they are added successively, and can not be added after mixing.
Polyferric sulfate is widely used as a polymer coagulant in various wastewater treatment, such as phosphorus removal,decolorization, SS removal and COD treatment. As a coagulant, PFS hydrolyzes to generate a large number of polymeric cations, which can neutralize the charged colloids in water, destroy the stability of the micelles, and make the micelle particles collide with each other through the electric double layer structure. The long-line structure formed by the hydrolyzed polynuclear complex ions can bridge the suspended particles in water, and the long-chain structures cross each other to form a network structure The results show that the system can be used to capture and sweep pollutants in water with high efficiency and strong coagulation.
In brief, compared with other coagulants, PFS has the following characteristics
1. Low cost and good effect;
2. High processing efficiency and high processing speed;
3. Safe, no secondary pollution and microorganism friendly;
4. Easy operation and strong adaptability.
Today in previous years, all walks of life have officially entered the right track after the Spring Festival, and everyone has put into active work. Then, due to the impact of the epidemic this year, many industries are still stagnant or semi stagnant, especially industrial enterprises. Without the start-up, there is no need for sewage treatment and no sewage treatment agent. Why is polyferric sulfate still in continuous supply and in large demand in the near future?
This is mainly due to the fact that industrial enterprises are basically the ones that stop production and reduce production at the present stage, while urban sewage treatment plants still need to continue to operate, and food plants, medical sewage treatment plants and some industrial enterprises are still in operation, while polymeric ferric sulfate can play its role of strong water purification in the above sewage treatment.
