Product Name: Polyacrylamide PAM Thickener
Cas: 9003-05-8
Other Names Polyacrylamide / Flocculant / PAM
Appearance White Crystal Powder
Purity >90%
CAS No.  9003-05-8
Packing 1kg per bag,25kg /drum,1 ton / Pallet
Application Sewage Water Treatment, Coal Mine Washing, Oil Field etc Use characteristics 1.PAM can make suspended matter through electric neutralization, bridging adsorption, and flocculation.
2. can play a role through mechanical, physical, chemical effects.
3.PAM can effectively reduce the frictional resistance of the fluid. Adding a small amount of PAM to the water can reduce the resistance by 50-80%.
4. PAM has thickening effect under neutral and acid conditions. When the pH is above 10, PAM is easily hydrolyzed. Thickening will be more pronounced when in a semi-mesh structure.   Effect condition Under normal circumstances, the use of polyacrylamide will increase the amount of flocculation, but the effect will be lower when it is used too much, and it will become a stable colloid. Followed by flocculation time: the combination of organic flocculant and inorganic flocculant, the biggest feature is that the largest particle floc can be obtained, and the oil droplets can be agglomerated or adsorbed out. The speed is too slow and the time is too short. The flocculant can not be in full contact with the solid particles, which is not conducive to the flocculant trapping the colloidal particles; and the concentration distribution of the flocculant is not uniform, which is not conducive to the role of the flocculant. The effect of polyacrylamide is also related to the water temperature: the reaction rate is too slow at low water temperature, the hydrolysis time increases, affecting the amount of water treated, and the excessively high viscosity of the flocculant will also make the floc fine. At high water temperatures, the reaction rate is too fast and fine flocs are formed. Description of the amount of polyacrylamide used
  1. The amount of cationic polyacrylamide used for coal washing can be set between 30 kg and 110 kg; the wastewater used in the chemical industry is generally between 50 and 120 kg; wastewater from the bleaching and dyeing industry The wastewater in the paper industry is the most difficult to handle. It should be increased in quantity. It is reasonable to set the quantity to be used in one hundred to three hundred kilograms. The electroplating wastewater industry and ordinary industrial water should not exceed 50 kilograms. Note: (The quantity used in these industries is the quantity of wastewater per thousand tons).

    2. The flocculant used for dewatering according to the different treatment methods is different.

    If the main body of the process uses biochemical methods, that is, excess sludge dewatering (possibly containing some primary sediment), only cationic PAM is required as the sludge dehydrating agent.

    If the main body of the process uses physicochemical methods, such as first-stage strengthening, loading magnetic separation and other processes, it is generally first added with PAC to temper, then an anionic flocculant, and finally dehydrated with a cationic flocculant. The specific dosage should be determined according to the quality of the sewage.

There are also many sewage treatment stations. The sludge dewatering can be directly added with PAC or other inorganic flocculating agents. This is widely used in plate and frame filter presses, especially in electronics factories or small sewage treatment stations.

PAM is generally used in a ratio of 0.1% to 0.2% when used as a sludge dehydrating agent. After being dissolved into a gelatinous liquid, it is added to the sludge for mixing treatment.

The ratio with sludge is generally between 5% and -10%, and some are lower. This is determined by the concentration of the sludge. It is best to determine the optimum dosage and type of use by on-site beaker experiments. Different sludges, different chemicals, different equipments, and different management levels have different sludge treatment effects.

3. The sewage treatment plant uses cationic polyacrylamide as a sludge dewatering agent for sewage operation. In the process of communicating with customers, customers often ask questions about the amount of sludge dehydrating agent to be added during the dewatering process of sewage sludge. To know the problem of the amount of sludge dehydrating agent relatively accurately, first understand the parameters, the moisture content of the sludge, the moisture content of the mud cake, the amount of the mud, the amount of the drug, and the concentration of the drug.
