Poly aluminium chloride (PAC) is a new type high efficiency inorganic polymer coagulant, adopting advanced manufacturing technique and quality raw material, show the features of low impurity, high molecula weight, and superior coagulating effect. 

I. Poly Aluminium Chloride Properties

1. Its dosage lower than aluminum sulfate (based on Al2O3) and water treatment cost is lower than other inorganic flocculants. 
2. The product can cause quick formation of flocs, big flocs formation and rapid precipitation. Its treatment capacity is 1.3-3.0 times of other inorganic flocculants. 
3. It enjoys wide-range adaptability for different-temperature source water and a good solubility. 
4. It is slightly corrosive and easy for operation. 
5. The liquid product is suitable for automatic dosing. Furthermore, it will not block pipes over long-time usage.

II. Description

III. Poly Aluminium Chloride Application:

1. Its purifying effect on low-temperature, low-turbidity and heavily organic-polluted raw water is much better than other organic flocculant, furthermore, the treatment cost is lowered by 20%-80%.

2. It can lead to quick formation of flocculant (especially at low temperature) with big size and rapid precipitation service life of cellular filter of sedimentation basin.

3. It can adapt to a wide range of pH value (5−9), and can reduce the pH value and basicity after processing.

4. The dosage is smaller than that of other flocculants. It has wide adaptability to the waters at different temperatures and at different regions.

5. Higher basicity, lower corrosive, easy for operation, and long-term use of non-occlusion.
