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.

 

PAFC's mainly performance and advantages:

 
1, hydrolysis speed, hydration weak. The formation of alum dense velocity faster. Affected by water temperature change is small, meet in the shear force generated in the process flow requirements.

 

2, solid product is brown, reddish-brown powder, easily soluble in water.

3, which can effectively remove the source of aluminum ions in water, as well as aluminum salts in the water after coagulation of free-state residual aluminum ions.

4, wide scope of application, drinking water, industrial water, domestic water, domestic sewage and industrial effluent treatment.

5. Less medication to deal with good effect, than any other coagulant 10-20% cost savings.

6. Using methods and packing, as well as attention to essentially the same matters with the PAC.

 

Usage

 
1. Solid PAC should be added after dissoved in water, and the dilution ratio is generally 2-20% (weight percent).

2. The dosage is generally 1-15 g solid PAC per MT raw water, and can be decided according to actual experiment according to different water quality and turbidness.

 

Cautions

 
1. This product mustn'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.
