Polyaluminium chloride(PAC) with white or pale yellow powder used in the drinking water Cas no.1327-41-9​

Features:

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.

 Applications:

1. The liquid product can be dosed directly or dosed after dilution. As for the solid product, dilution is necessary before being dosed. Water amount for dilution shall be determined based on the amount of the chemical to be dosed and the quality of water to be treated. Dilution proportion for solid product is 2%-20%, and for liquid product, 5%-50% (based on weight percentage).

2. The dosage of the liquid product is 3-40g/MT and the dosage of the solid product is 1-15g/MT. The specific dosage is based on the flocculation test and on the trial.

3. Its acidity is lower than other inorganic coagulants.

Advantages

PAC's can offer a number of advantages over traditional coagulants such as alum or iron salts. Because PAC's are pre-neutralized and have a higher charge density than traditional coagulants, they coagulate via a more efficient mechanism, called charge neutralization. This allows PAC's to be effective at lower doses than alum or iron salts, when one compares the actual metal being added by the coagulant to the system. Resulting benefits can include:

• Less pH depression and alkalinity depletion, reducing lime or caustic requirements
• Reduced chemical sludge volumes.
• Sludge density is increased.
• Improved results in higher pH systems.
• Better performance in cold water.

And because PAC does function so differently, there are many applications where it will provide finished water quality that the traditional coagulants can't achieve.
