Selecting the right flocculant is one key to success. When choosing the type of polyacrylamide flocculant, to consider factors: 1, the user understand the source of the sludge, nature, components (such as organic / inorganic ratio) and solid content. Generally speaking cationic flocculant for treating organic sludge, anionic flocculant for treatment of inorganic sludge; not with a cationic coagulant alkaline strong, but not strong acidic anionic flocculant; high solid content The sludge is usually larger amount of flocculant. 2, floc size: floc is too small will affect the drainage rate, much more will make the floc bound water and reduce mud biscuits. Flocculant molecular weight can be adjusted by selecting the floc size. . Ion of flocculants: for sludge to be dehydrated, with different ions of flocculant in the lab screened to select the most appropriate person. This is to get the best flocculation effect, but also make the least amount of dosage. 4, floc strength: floc under shear should be stable and not broken. Flocculant molecular weight increase or select the appropriate molecular structure contributes to better floc stability. 5, mixed flocculant and sludge: dewatering equipment flocculant in a position to be sufficient to react with the sludge, flocculation occurs. For this reason, the flocculant solution viscosity must be appropriate, under the conditions existing equipment can be uniformly mixed with the sludge. Both mixed or not, it is another critical success factor. Configuring concentration flocculant solution viscosity related to its molecular weight. 6, flocculant dissolution: dissolve well in order to give full play to flocculation. Sometimes the need to accelerate the rate of dissolution, then can consider increasing the flocculant solution concentration (the higher the concentration, the faster dissolution), using emulsion flocculant, or an appropriate increase in water temperature
