Poly Aluminium Ferric Chloride / PAFC

Polyaluminum ferrous chloride  PAFC

1.it is a kind of PSAA that produced from aluminum and iron salts based Aluminum and iron salt coagulant hydrolysis mechanism, based on principles of synergy, by adding iron ions, or three single-quality iron oxide and other iron-containing compounds, compound and obtained a new type of high efficient coagulant.

2.It combines the respective advantages of aluminum and iron salts of aluminum ions and iron ions have a significant improvement in form, polymerization degree increased substantially.

3.Take aluminum, iron coagulant their respective advantages at flotation operation to improve the PAC coagulation performance; of high turbidity water and low temperature and low turbidity water purification treatment effect was particularly evident from time to increase alkaline additives or other coagulant.

This product is inorganic macromolecular coagulant, which is made by polyaluminum chloride complexing with polymeric. Therefore, the molecular structure is enlarged; the capacity of neutralization and bridging adsorption is enhanced. It is an ideal chemical to treat heavily organic-polluted raw water as well as low-temperature and low-turbidity, low-temperature and high-turbidity water.

Properties

It combines the coagulate advantages of aluminum salt and ferric salt; can lead to quick formation of close flocs and rapid precipitation.

It has wide-range adaptability to the waters at different temperatures and a good solubility.

The dosage is smaller than that of other flocculants, which is better for improving the quality of treated water.

It is suitable for the automatic dosing.

Application Method & Notes:

1.The liquid product can be dosed directly or dosed after dilution. Dilution is necessary before dosing for the solid product. The normal dilution ratio for the solid product is 2%-20%, and 5%-50% for the liquid product (based on weight percentage).

2.The specific dosage is based on the flocculation tests and trials by the users. The usual dosage of the liquid product is 3-40 g/ton, and of the solid product, 1-15 g/ton.

3.The product can not be stored with other chemicals.

4.For the liquid product, we provide special tanks for transportation to the clients, and afford the storage tank. The solid product is packed in inner plastic bags and further in polypropylene woven bags, with each bag containing 25 Kg.

5.The shelf life is six months for liquid product and one year for the solid product. The product should be stored in a dry and ventilated place, but the effect will not be affected even if it gets wet.

Packing:
25kg/polypropylene woven bags with inner plastic bag, 25kg/PE bag

Storage:
1.This product musn't be stored with other chemical reagents.
2.Solid products should be stored in a ventilated and dry place with the storage period of two years, and the availability won't be changed after the product is affected by damp. Poly Aluminum Ferric Chloride(PAFC) combines the advantages of aluminum salt and ferric salt, and can lead to quick formation of close flocs and rapid precipitation.
