Wastewater Treatment Chemicals Spray Dried Polyaluminum Chloride Powder PAC 30%

Polyaluminum Chloride. Also known as water purifier or coagulant, it is a water-soluble inorganic polymer between ALCL3 and AL(OH)3, with the chemical formula [AL2(OH)NCL6-NLm]. where m represents the degree of polymerization and n represents the neutrality of the PAC product.

Compared with other flocculants, this product has the characteristics of wide application range and wide adaptability. The flocculation is simple and fast, and the sedimentation performance is good. The suitable pH range is large (between 5-9), and the pH and alkalinity of the treated water are low. The low water temperature maintains a steady precipitation effect. The alkalinity is higher than other aluminum salts and iron salts, which has less effect on equipment corrosion.

It mainly compresses the double layer, and plays the role of electric neutralization, adsorption bridging, sedimentation net capture and other mechanisms, so that the tiny suspended particles and colloidal ions in the water are destabilized, and the purification treatment effect is produced through flocculation, coagulation and precipitation. .

Polyaluminum Chloride Advantages

1. The water quality after water purification is about 15%-30% lower due to the aluminum sulfate flocculant.

2. The agglomerate is formed quickly, the precipitation is fast, and the processing capacity is larger than that of traditional products such as aluminum sulfate.

3. The alkalinity in water is less consumed than various inorganic flocculants. Because it is impermeable to alkali agents, it can also be less penetrated.

4. It is suitable for condensation in the range of water pH 5.0-9.0, and the pH and alkalinity of the treated water are small.

5. The alkalinity is higher than other aluminum salts and iron salts, the equipment erosion effect is small, and the operating conditions are good.

6. Less salt increase in the treated water, which is also good for ion exchange treatment and high-purity water agents.

Solubility is better than aluminum sulfate.

8. Compared with inorganic flocculants such as aluminum sulfate, it has better adaptability to source water temperature.
