What is PAC (Polyaluminium chloride)?

The PAC (Polyaluminium Chloride) enjoys wide-range adaptability for different-temperature source water and a good solubility. PAC is slightly corrosive and easy for operation, and it is suitable for automatic dosing. Furthermore, it will not block pipes over long-time usage.

What is the treatment capacity of polyaluminium chloride?

Its treatment capacity is 1.3-3.0 times of other inorganic flocculants. The PAC (Polyaluminium Chloride) enjoys wide-range adaptability for different-temperature source water and a good solubility. PAC is slightly corrosive and easy for operation, and it is suitable for automatic dosing.

How is PAFC synthesized?

PAFC was synthesized following two steps: First, 50 g of blast furnace dust was placed in a 500 mL three-necked round bottom flask equipped with stirrer and reflux device. Then, 2 g NaF, 150 mL of HCl diluted solution (36%, freshly diluted 1:1 with ultrapure water) and 5 mL of HNO 3 were added.

What are the uses of Pac?

PAC is slightly corrosive and easy for operation, and it is suitable for automatic dosing. Furthermore, it will not block pipes over long-time usage. – Urban water purification: River water, reservoir water, groundwater. – Industrial water purification. – Urban sewage treatment.

How to extract (Al + Fe) B species from PAFC?

The mixture solution of ethanol, propylene glycol, and acetone could be used as precipitation solvents to extract the (Al + Fe) b species from PAFC. The optimal separation and purification conditions were organic solvents volume ratio = 2:1:7 and the middle organic solvents dosage V2 = 100 mL ( V1 = V3 = 50 mL, for 10 mL of 0.3 M PAFC solution).

What is a (Al + Fe) species in PAFC?

The (Al + Fe) species in PAFC was divided into (Al + Fe) a, (Al + Fe) b and (Al + Fe) c by the Ferron timed complex-colorimetric method , where the (Al + Fe) b species was defined as the medium polymeric species of (Al + Fe) in PAFC (showing a reaction time with Ferron from 1 to 240 min).
