| Polyaluminium chloride |
|
Polyaluminium chloride is a new-type inorganic polymeric flocculant, chemical formular: [Al2(OH)nCl0-n]m. It can greatly decrease the colloid electric charge of the clay and other impurities in water. |
|
[Use]
- In the purification of drinking water, daily-life use water
- In the treatment of industrial waste water.
- In precise foundry, pharmacy, paper making and leather making etc.
|
|
[Features]
- Good adaptability. It can maintain good purifying effect in wide range of PH value of water.
- Has excellent purifyng effect on water with high turbidity.
- High settling velocity, high activity, strong filtering power. Has good purifying effect on microbes, algae, radioactive substances, heavy metal containing Pb2+ and cr3+ etc.
- Better than traditional water purifying agents such as aluminium sulphate, ferrous sulfate, ferric chloride etc.
- Less corrsion to pipes and equipments.

[Application method]
Liquid product can be directly used. Solid product: prepare solution at the ratio of 1:3. (at 20°C, the specific weight is about 1.15-1.20); can alos be directly used, and stir it for use. |
|
[Use level]
- Liquid product: use level is about 1/30,000 of water; solid product: use level is 1/100,000 of water.
- When it is used in waste water treatment, the PH of the waste water should be first adjusted to neutral, and then determine the use level of the products.
