1. Polyaluminium chloride
Polyaluminium chloride is a kind of inorganic high polymer coagulant. It is a kind of inorganic high polymer water treatment agent with high molecular weight and high charge, which is produced due to the bridging effect of hydroxyl ion and the polymerization effect of multivalent anion.
Application characteristics: 1. The flocculant is fast in forming, active and filterable. 2. No need to add basic auxiliaries. If it is deliquesced, its effect will not change. 3. It has wide pH value, strong adaptability and wide application. 4. The treated water is less salty. 5. It can remove the pollution of heavy metals and radioactive substances to water. 6. High effective ingredients, easy to store and transport.
2. Polyferric sulfate
The morphology of PFS is a light yellow amorphous powder solid, which is very soluble in water. The 10% (weight) aqueous solution is a red brown transparent solution with hygroscopicity. Polymeric ferric sulfate is widely used in the purification of drinking water, industrial water, various industrial wastewater, urban sewage, sludge dewatering and so on.
Application features: 1. New type, high quality and high efficiency inorganic high polymer flocculant; 2. Excellent coagulation performance, dense alum flowers, fast settling speed; 3. Excellent water purification effect, good water quality, no harmful substances such as aluminum, chlorine and heavy metal ions, no water phase transfer of iron ions, non-toxic, harmless, safe and reliable; 4. The functions of turbidity removal, decolorization, oil removal, dehydration, bacteria removal, deodorization, algae removal and removal of COD, BOD and heavy metal ions in the water are significant; 5. The range of pH value suitable for the water body is 4-11, and the optimal range of pH value is 6-9. After purification, the change range of pH value and total alkalinity of the raw water is small, which has little corrosiveness to the treatment equipment; 6. The effect of purification of micro polluted, algal, low temperature and low turbidity raw water is significant, especially for high turbidity raw water; 7. The dosage is small, the cost is low, and the treatment cost can be saved by 20% - 50%.
3. Polyacrylamide
Polyacrylamide (PAM) is a kind of water-soluble polymer, which is insoluble in most organic solvents. It has good flocculation and can reduce the friction resistance between liquids. According to the ionic characteristics, PAM can be divided into four types: non-ionic, anionic, cationic and amphoteric.
