Selecting the right flocculant is one of the keys to success. When selecting the type of polyacrylamide flocculant, to consider factors: 1, the user understand the source of the sludge, the nature, composition (such as organics / inorganic scale) and solid content. Generally, cationic flocculant for the treatment of organic sludge, and anionic flocculant for treating inorganic sludge; not with cationic coagulant alkaline strong, but not strong acidic anionic flocculant; high solid content flocculant sludge is usually a larger amount. 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 the flocculant: Aiming to be dewatered sludge with different ionic flocculant degree in laboratory screening, select the most appropriate person. This is to achieve the best flocculation effect, but also make the least amount of dosing. 4, floc strength: floc under shear should be stable and not broken. Increase the molecular weight flocculant or select the appropriate molecular structure helps improve floc stability. 5, mixed with sludge coagulant: flocculant in a position dewatering equipment must be fully react with sludge flocculation. For this reason, the flocculant solution viscosity must be suitable, under the conditions existing equipment can be uniformly mixed with the sludge. Both mixed or not, is another critical success factor. Configuring concentration flocculant solution viscosity related to its molecular weight. 6, dissolved flocculant: Good to be fully dissolved 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, etc.
