3.Physical and chemical index as below:
Index name | index | |
Liquid | solid | |
Alumina (AL2O3) content % ≥ | 10.0 | 29.0 |
Basicity % | 40.0-90.0 | |
Density (20oC)/(g/cm3)≥ | 1.12 | - |
Water insoluble /% ≤ | 0.1 | 0.3 |
PH (10g/L aqueous solution) | 3.5-5.0 | |
Arsenic (As) content %≤ | 0.0002 | |
Lead (Pb) content % ≤ | 0.001 | |
Cadmium (Cd) content % ≤ | 0.0002 | |
Mercury( Hg) content % ≤ | 0.00001 | |
Hexavalent chromium contents %≤ | 0.0005 | |
Note: Above list As,Cd,Hg,Cr+6,insoluble index of liquid products are calculated on the basis 10% of AL2O3,when the content of AL2O3≥10% ,the impurities index is calculated according to AL2O3 10% product proportion converted by actual amount. | ||
4. Usage and application
Application: It’s widely used in purification in drinking water, urbon and industrial water etc.Usage:The ender can remedy concentration after testing and choose the optimum dosage according to different water.
1. Solid PAC should be used after being dissolved in water and the dilution ratio is generally 2%-20%( weight percentage )
2. Liquid PAC can be added directly and can also added after dilute. The dosage is generally 1-15g per ton.
By the way, other specific dosage should be subject to users' actual experiment considering the specific water quality and turbidity.
5.Packing and storage:
Packed in 25kg/bags plastic woven bag with inner plastic bag, Or according with your request 17MT in 20 feet container.
Storage methods:Stored in cool and dry place; protect against sunlight and rain
flocculation effect Poly Aluminum Chloride (PAC)
