High Ionicity Cationic Polyacrylamide Flocculant For Municipal Sewage Desliming

Product features of cationic polyacrylamide (CPAM): The appearance of cationic polyacrylamide (CPAM) is white powder with ionicity ranging from 10% to 65%. It can be dissolved in water in any proportion and insoluble in organic solvents. With the characteristics of high polymer electrolyte, it is suitable for the treatment of wastewater with negative charge and rich organic matter. It is suitable for wastewater treatment with high organic colloid content in dyeing, papermaking, food, construction, metallurgy, mineral processing, coal powder, oil field, aquatic product processing and fermentation, etc. It is especially suitable for urban sewage, urban sludge, papermaking sludge and other industries. Dewatering of sludge.

Precautions for the use of cationic polyacrylamide
1. The size of flocs: too small flocs will affect the speed of drainage, while too large flocs will constrain more water and reduce the degree of mud biscuit. The size of the flocs can be adjusted by selecting the molecular weight of the polyacrylamide.
2. Sludge characteristics: The first point is to understand the source, characteristics and composition of sludge, and its proportion. According to the different properties, sludge can be divided into organic and inorganic sludge. Cationic polyacrylamide is used to dispose of organic sludge, while the relative anionic polyacrylamide flocculant is used for inorganic sludge. Anionic polyacrylamide is used when the alkalinity is strong, and anionic polyacrylamide is not suitable when the acidity is strong. When the sludge is high, the amount of polyacrylamide is usually large.
3. Floc strength: The floc should be stable and not broken under shearing action. Improving the molecular weight of polyacrylamide or choosing a suitable molecular structure can help to improve the stability of the floc.
4. Ionic degree of polyacrylamide: For dewatered sludge, flocculants with different ionic degrees can be used to select the best suitable polyacrylamide, so that the best flocculant effect can be obtained. It can also minimize the amount of dosing and save costs.
5. Dissolution of polyacrylamide: Only when the dissolution is good can the flocculation effect be fully exerted. Sometimes it is necessary to speed up the dissolution rate, at this time, it is possible to consider increasing the concentration of the polyacrylamide solution.
In fact, when treating sewage at ordinary times, some sewage cannot be achieved by using a single flocculant, and must be used in combination. The inorganic flocculant PAC and polyacrylamide composite flocculant are used to treat sewage. However, when adding the medicine, pay attention to the order, if the order is not correct, the effect will not be achieved.
