Cationic Polyacrylamide Flocculant

Our cationic polyacrylamide flocculants is amorphous, free-flowing powder, with Molecular Weight: 1 to 15 million.

Cationic Flocculants is widely used in sludge thickening, dewatering and municipal wastewater treatment, paper making and oil & gas process.

To make the 0.3% solution, weigh 1.200g of polyacrylamide powder accurately and add into 400ml of water in a 600ml beaker. The mixer motor must be capable of maintaining 800-1000 rpm to increase the solution viscosity for 30-35 minutes. The finished solution should be clear and homogeneous.

Cationic polyacrylamide is mainly used in high speed centrifuge, belt filter press, plate frame filter machine and other special sewage machines. Cationic polyacrylamide has good effect in the formation of floc speed, extrusion resistance and shear, easier to peel and filter cloth and other characteristics. So it is with high dehydration rate, low moisture content of filter cake, use rarely, can be very good to help customers reduce the cost in use can be used, hydrochloric acid, sulfuric acid concentration in the liquid when used in separation and purification containing suspended substance. Because of its unique chemical and physical properties, it has made a wide use of the effect. Therefore, the actual use of this is widely applied to the sludge dewatering treatment of urban sewage treatment plants, breweries, food factories, tanneries, petrochemical plants, oil fields, metallurgy, chemical industry and cosmetics.  

When polyacrylamide used for flocculation, the polyacrylamide molecular chain is fixed on the surface of different particles, and the particles of each particle form a polymer bridge to make the particles form aggregates and settle. And charge group particles on the polyacrylamide molecule could have surface adsorption effect.

It mainly depends on the nature of water treated. If the impurities in the water particles larger, and with a certain charge, then the treatment performance of cationic polyacrylamide alone sometimes is good. If the impurities particles are small and non-charged, then it shall be added inorganic flocculants first and then add cationic polyacrylamide powder. An experiment is usually taken before answer this question. Without adding inorganic flocculants, add polyacrylamide directly to see if the impurities in the water flocculation can be flocculated. If the flocculation of water can clarify, then there is no need to add inorganic flocculants. If not then it should be used with inorganic flocculants.

Polyacrylamide is most commonly used as flocculants, abbreviated as PAM. Flocculants is the linear polymer. Besides polyacrylamide solid aluminum sulfate, liquid aluminum sulfate, alum, polyaluminum chloride, ferric chloride, ferrous sulfates are also used as flocculants.

First, select a well-ventilated and dry warehouse, and to reduce the time of sunlight as the sun exposure will make polyacrylamide molecular weight degradation. Moisturizing polyacrylamide is easily to agglomerate and hard to dissolve as an aqueous solution during dissolution. If in a solution case, after the polyacrylamide dissolved in aqueous solution not used up, the remaining polyacrylamide solution should be filled with a lid seal to prevent dust from entering. The storage time of cationic polyacrylamide is 48 hours, and for cationic polyacrylamide is generally not more than 12 hours. The solution becomes thinner when the polyacrylamide solution is stored for an extended period of time.

The handling of polyacrylamide will be simpler than powders as in-line injection could be used with shorter dissolution time and no solubility problems. Powders are very stable during storage in physical setting and formation.

Emulsions must be stored indoor with temperature of 5oC to 30oC. In the storage and handling, the emulsion could not be contaminated with water. To keep the surface dry and ventilated. Before using after a long period, homogenizing is needed by gentle agitation with short periods. After a first opening and partial consumption the package must be closed tightly.

Sinofloc technical team could provide in-house testing and lab facilities to optimize products performance with the best combination of flocculants in your conditions.

Sinofloc has the ability and experience to ship our flocculants to any port in the world. Door to door practice is also available.

Polyacrylamide as a polymer organic polymer, when dissolved, it will take a certain time to stir for the molecular chain of polyacrylamide to be fully opened. When the water temperature is too low, the dissolution rate of polyacrylamide will slow down. In winter, the mixing time of polyacrylamide is usually extended for half an hour for molecular chain to be fully expanded. If it is available, to heat the water to 20 to 30 degrees is also a good method to speed up dissolving. The water temperature cannot be too high, otherwise the high water temperature will accelerate the degradation of polyacrylamide, and affect the use effect.
