Application

Descriptions:

• PAC (Poly Aluminum Chloride) normally has three types, pure white grade (white), drinking water grade (light yellow) and waste water grade (brown yellow).

• PAC is accompanied with the chemical processes such as electrochemistry, coagulation, absorption and precipitation in its hydrolytic process.

• PAC is high-efficient, economic and nontoxic inorganic high molecular compound.

• PAC is easily soluble in water.

• The liquid PAC is suitable for automatic dosing, and it will not block pipes over long-time usage.

Product Advantages:

Good effective and lower cost:

• PAC has purifying effect on low-temperature, low-turbidity and heavily organic polluted raw water.

Flocculation ability:

• PAC can lead to quick formation of flocculants with big size and rapid precipitation service life of cellular filter of sedimentation basin.

Broad range of pH:

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

Adapting to various source of water:

• PAC has wide adaptability to the waters at different temperatures and regions, with less dosage than other flocculants.

Uses:

• PAC is widely used for purification of industrial waste water.

• PAC is widely used for purification of drinking water.

• PAC is used for separation of coal and water with excellent effect in coal industry, and separation of oil and water in oil refining industry.

• PAC is used for treatment of blast furnace gas washing water.

• PAC is used for paper sizing, dye printing, bleaching, dyeing, leather, refractory material, medicine, cosmetic industry and other industries.
