The main use of polyacrylamide is used for water purification, and there are many kinds of
polyacrylamide, the use of methods and precautions naturally vary, then we need to pay attention to what aspects of the use of this polyacrylamide in the use of polyacrylamide?
1, sludge characteristics. A little understanding of the source of sludge, characteristics and composition, the proportion. According to the nature of the difference, sludge can be divided into organic and inorganic sludge two kinds. Polyacrylamide is used for disposal of organic sludge, relative anionic polyacrylamide flocculant for inorganic sludge, alkaline is very strong with polyacrylamide, and acid is very strong when it is not appropriate to use anionic polyacrylamide, solid content is high when the sludge is usually polyacrylamide dosage is also large.
2, the ionic degree of polyacrylamide: for dewatering of sludge, different ionic degree of flocculant can be used to stop the selection of the first small test, selected the appropriate polyacrylamide, so that you can get the effect of flocculant, but also to make the amount of dosage is less, saving money.
3, the size of floc: floc is too small will affect the drainage speed, floc is too big will make the floc constrain more water and reduce the mud biscuit degree. After selecting the molecular weight of polyacrylamide, the size of floc can be adjusted.
4, floc strength: flocs should be stable and not broken under shear. Progress in the molecular weight of polyacrylamide or choose the appropriate molecular structure to help improve the stability of flocs.
5, the dissolution of polyacrylamide: good dissolution is the only way to give full play to the flocculating effect. Sometimes the need to speed up the dissolution rate, this time can be considered to improve the concentration of polyacrylamide solution.
The use of polyacrylamide, note that these aspects mentioned above, as well as the use of the late need to add in accordance with the steps, you can achieve better water purification effect.
