Our flocculants are specially designed for the treatment of various types of industrial wastewater, such as municipal or paper industry wastewater. When added into turbid water suspended with particles, flocculants neutralize the electric charges of polymeric particles suspended in the water and promote adsorption and bridging of these polymers. As result, rapid agglomeration and the sedimentation will occur, leading to faster separation and clarification of the wastewater, and thereby improve operating efficiency and reduce costs.
Flocculants: Types, Properties and Applications
Table 1: Major Types of Flocculants
| Type | Chemical Composition | Charge | Molecular Weight |
|---|---|---|---|
| Anionic PAM | Polyacrylamide with carboxyl groups | Negative | 5–25 million Da |
| Cationic PAM | Polyacrylamide with amine groups | Positive | 3–20 million Da |
| Nonionic PAM | Pure polyacrylamide | Neutral | 5–15 million Da |
| Inorganic | Aluminum sulfate, ferric chloride | Positive/Negative | Low MW |
| Natural | Chitosan, starch derivatives | Variable | 10k–500k Da |
Table 2: Key Performance Characteristics
| Property | Anionic PAM | Cationic PAM | Nonionic PAM | Inorganic |
|---|---|---|---|---|
| Solubility | High | High | High | High |
| pH Range | 5–10 | 2–9 | 2–12 | 2–8 |
| Dosage (ppm) | 0.5–5 | 1–10 | 1–8 | 50–500 |
| Sludge Volume | Low | Medium | Medium | High |
| Cost | Medium | High | Medium | Low |
Table 3: Industrial Applications
| Industry | Preferred Flocculant | Function |
|---|---|---|
| Wastewater | Anionic/Cationic PAM | Clarification, sludge dewatering |
| Mining | Anionic PAM | Tailings settling, water recovery |
| Paper | Cationic PAM | Retention aid, drainage improvement |
| Food Processing | Nonionic PAM | Protein separation, juice clarification |
| Oil & Gas | Cationic PAM | Drilling fluid treatment |
Table 4: Advantages & Limitations
| Flocculant | Advantages | Limitations |
|---|---|---|
| Anionic PAM | High efficiency, low sludge volume | Less effective in acidic conditions |
| Cationic PAM | Works with organic sludge | Expensive, sensitive to pH |
| Nonionic PAM | Broad pH compatibility | Lower charge density |
| Inorganic | Low cost, fast action | High sludge production |
Table 5: Environmental & Safety Considerations
| Parameter | PAM-Based | Inorganic |
|---|---|---|
| Biodegradability | Low (but non-toxic) | High |
| Toxicity | Low (monomer control) | Medium (metal ions) |
| VOC Emissions | None | None |
| Handling | Dust control needed | Corrosive, pH control |
Flocculants are essential for solid-liquid separation in water treatment and industrial processes. Polyacrylamide (PAM)-based flocculants dominate due to their high efficiency, while inorganic coagulants remain cost-effective for some applications. Selection depends on water chemistry, sludge characteristics, and cost considerations.
