I. Composition of Flocculant Raw Materials
Flocculants are mainly composed of two types of raw materials: natural polymers and synthetic polymers. The natural category includes traditional materials such as alum and starch, while the synthetic category is represented by polyacrylamide. These raw materials work through charge neutralization and adsorption bridging to cause suspended particles in water to aggregate and settle.
II. Characteristics of Common Flocculants
Inorganic flocculants: mainly aluminum and iron salts, suitable for treating water with low turbidity.
Organic polymers: Outstanding effect in treating industrial wastewater
Compound type: Combining the advantages of both, it has strong adaptability.
III. Considerations for Raw Material Selection
Different water qualities require different raw material ratios:
Domestic sewage: Emphasis on phosphorus and nitrogen removal formula
Industrial wastewater: Removal of heavy metals needs to be considered.
Drinking water: Strict requirements for the purity of raw materials.
