Note: Indicators of As, Pb, Cd, Hg and Cr6+ insoluble of liquid products listed in the above table should be
calculated by Al2O310%. When Al2O3 content is ≥10%, indicators of impurities should be calculated by
converting the actual content to Al2O310% product proportion.
Poly aluminium chloride (PAC) is a new type high efficiency
inorganic polymer coagulant, adopting advanced manufacturing
technique and quality raw material, show the features of low
impurity, high molecula weight, and superior coagulating effect.
The produces different greades of Polyaluminum Chlorides (PAC) in
powder and liquid forms. The highly charged Al in the products is
optimized for best performance for the different basicities of PAC.
The low to medium basicity products are effective coagulants for
treatment of both drinking water and waste water. And the medium to
high basicity products are excellent for all ranges of wastewater
1. The user can allocate remedy concentration by test and determine
the optimum dosage according to different to be added after they
are dissolved and diluted.
2. The dilution ratio of liquid product is 5-50%, and the dilution
ratio of solid product is 2-20%.
3. The liquid product dosage is 3-40kg/1000 tons water, and solid
product dosage is 1-15kg/1000 tons water.
4. The amount of specific dosing is based on coagulation tests and
Widely used in the purification of drinking water, urban water
supply and industrial water supply, etc...
1. Good effective and lower cost.
Its purifying effect on low-temperature, low-turbidity and heavily
organic polluted raw water is much better than other organic
flocculant, furthermore, the treatment cost is lower.
2. Flocculation ability .
It can lead to quick formation of flocculantwith big size and rapid
precipitation service life of cellular filter of sedimentation
3. PH broad in scope.
It can adapt to a wide range of pH value (5−9), and can reduce the
pH value and basicity after processing.
4. Adopting to various source of water.
The dosage is smaller than that of other flocculants. It has wide
adaptability to the waters at different temperatures and at
5. Higher basicity, lower corrosive, easy for operation, and
long-term use of non-occlusion.
