PH2 Industrial Chemicals 98% Poly Ferric Sulphate

1

Dissolved in pond in 20-50% concentration, stirred it, then standing to till the water is brown red

2

According the original medicine, its dosage is equal to polyaluminum chloride, is 1/3~1/4 of solid aluminum sulfate. The solution follows the concentration

3

During use, feeding the medicine by measure tank 

4

Generally the Ferric sulpahte working solution shall be used right after preparation. Use pure tap water for preparation. Sometimes slight precipitation may occur depending on the water used.

 Keep close attention to the progressof the application which may be divided into three stages:
        (1)Coagulation: Large amount of micro flocs formed in a very short time after the PFS working solution is mixed with raw water. The water turns more turbid. Vigorous stirring is needed at this stage, usually 250-300r/min in sample test for 10-30S, at the maximum not exceeding 2min.
        (2)Flocculation: The micro flocs grows to form large ones. Mild stirring at first and then standing for 10-15min is required at this stage. In the sample test, stir at 150r/min for 6 min, then 60r/min for 4 min.
        (3)Sedimentation: water flow shall be very slow at this stage for floc settling. To achieve high efficiency, lamella settling or flotation method can be used. In the sample test, stir at 20-30r/min for 5 min, stand for 10 min, and test turbidity.   

6

Compulsive filtration: choose suitable filter material or filter aid to achieve good capture effect and filtration speed. This is a key step for improvement of water quality.

1

Has the same features as inorganic flocculants such as polyaluminum chloride, etc.

2

It is suitable for phosphorus removal of life sewage wastewater treatment plant or improving the hydrophobicity of sludge.

3

Low use level and cheap cost;

4

Specially effective to treat the wastewater from oil field and oil extraction,coking wastewater.
