Polyacrylamide (PAM) is a type of high-molecular flocculating agent used to treat water. It is also a kind of high molecular polymer of linear organics. Around the same time, suspended particles will also be adsorbed in water and play a role in binding and bridging the particles, allowing the fine particles to create comparatively large flocks and accelerating the rate of precipitation. This mechanism is called flocculation. It is commonly used in domestic sewage treatment because polyacrylamide has such a positive effect.
Is polyacrylamide unsafe? Is polyacrylamide poisonous? What does polyacrylamide mean?
Polyacrylamide is classified as all sorts of additives, and its primary purpose is to be used in the water treatment process as a precipitant, flocculant and sludge dehydrating agent; it has been used in several industries. In fact, polyacrylamide, apart from being used as a sewage flocculant, is used as a flotation agent and clarifier in the field of coal washing and mineral processing; thickener in the fragrance making and building industry; sizing agent and finishing agent for garment sizing; protein extraction agent; gelatin clarifier and paint mist.
What’s polyacrylamide, then?
Polyacrylamide is a high-molecular fiber soluble in liquids. To form a glue like substance prior to use, solid polyacrylamide must be dissolved in tap water. In fact, the solid polyacrylamide configuration process is also the polyacrylamide ripening process. In this manner, it is possible to extend its molecular chain and put into full play its powerful coagulation effect.
Dissolving polyacrylamide absolutely is not easy.
1. The temperature of the water does not exceed 60 °C.
2. The concentration is indicated to be regulated in the range of 0.1 percent – 0.3 percent.
3. It is important to dissolve it in clean water (such as tap water).
4. To dissolve the solvent, do not use iron, which will resist oxidation.
5. Polyacrylamide should be applied slowly and uniformly into the stirring water before dissolving, and the stirring speed should not be high (the linear velocity at the end of the stirring blade should be regulated below 8 m/s) to prevent the reduction of the force reducing polyacrylamide shear; if the feeding speed is too fast, it can also form a ‘fish eye.’
Pay attention to the points above, it will play its position more efficiently.
Application of the polyacrylamide effect
Many sewage treatment plants are always found, in particular in the southern zone, where the atmosphere is relatively humid. In sewage treatment plants, some of the polyacrylamide is not closely packed or stacked up for a long time, which contributes to moisture absorption and caking. Many people will wonder if such polyacrylamide is invalid and can be reused in spite of the containment of polyacrylamide flocculant. You must closely look at the following sentence if you ever find such a query. In fact, the water solution has viscosity for as long as you can dissolve it, so it does not fail. However, the agglomerated polyacrylamide is very difficult to dissolve, which also means failure.
In the field of environmental protection, polyacrylamide is increasingly commonly used, especially in industrial sewage and domestic sewage. It is commonly used in urban wastewater treatment plants, commercial wastewater treatment plants, the paper industry, the dairy industry, the garment industry, the beer industry, the petrochemical industry, the wastewater treatment industry and the oilfield wastewater treatment industry.
