Polyaluminium-Chloride PAC
CAS Number: 1327-41-9
Chemical name: Polyaluminium-Chloride
Descriptions:
This product is high-effective inorganic polymer coagulant. It is widely applied in water purification, wastewater treatment, precision cast, paper production, pharmaceutical industry and daily chemicals.
Features and Applications:
This product is a new-type inorganic macromolecule coagulant with high efficiency. It is widely used in the drinking water, industrial water purification, industrial effluent municipal sewage treatment.
It can lead to quick formation of flock with big size and rapid precipitation.
It has wide-range adaptability to the waters at different temperatures and a good solubility.
The product is slightly corrosive and suitable for the automatic dosing and convenient for operation.
Advantages:
1. Its purifying effect on low-temperature, low-turbidity and heavily organic-polluted raw water is much better than other organic flocculants , furthermore, the treatment cost is lowered by 20%-80%.
2. It can lead to quick formation of flocculants (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 different regions.
5.Higher basicity, lower corrosion, easy for operation, and long-term use of non-occlusion.
