How to quickly and accurately select the appropriate flocculant? Before treating wastewater, it is necessary to consider the type of wastewater first, so as to select coagulants more accurately and quickly. So, what aspects can we consider when choosing a flocculant type number?
Sludge is a product of wastewater treatment. To understand the source, properties, composition, and solid content of sludge. According to the different main components contained in sludge, sludge can be divided into organic sludge and inorganic sludge. Generally speaking, cationic flocculants are used to treat organic sludge, while anionic flocculants are used to treat inorganic sludge. Cationic flocculants are not easy to use when the alkalinity is strong, and anionic flocculants should not be used when the acidity is strong. When the solid content of sludge is high, the amount of flocculant used is usually larger.

Ionic degree selection of coagulants: For the sludge to be dehydrated, coagulants with different ionic degrees can be used. Through small experiments, ideal and suitable coagulants can be selected to achieve the desired flocculant effect, reduce dosage, and save costs.
The key to choosing ionization degree is: the size of flocculation; Flocculation strength and moisture content.
The key to choosing ionization degree is: the size of flocculation; Flocculation strength and moisture content. Size of flocculation: If the flocculation is too small, it will affect the drainage speed. If the flocculation is too large, it will not be able to bind more water and reduce mud. The size of the flocculant can be adjusted by selecting the molecular weight of the flocculant.
Flocculation strength: Flocculation should remain stable and not break under shear action. Increasing the molecular weight of flocculants or selecting appropriate molecular structures can help improve their stability.
Mixing of flocculant and sludge: The flocculant must fully react with the sludge at a certain position in the dewatering equipment in order to cause flocculation. For this reason, the viscosity of the flocculant solution must be appropriate and able to mix thoroughly with the sludge under existing equipment conditions. Whether the two are evenly mixed is a key factor for success. The viscosity of flocculant solution is related to its molecular weight and formulation concentration.
The dissolution of coagulants: Only when dissolved well can the coagulant's effect be fully utilized. Sometimes it is necessary to accelerate the dissolution rate. At this point, you can consider increasing the concentration of the flocculant solution.
