Polyaluminium Chloride

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.

1. Its dosage lower than aluminum sulfate (based on Al2O3) and water treatment cost is lower than other inorganic flocculants.
2. The product can cause quick formation of flocs, big flocs formation and rapid precipitation. Its treatment capacity is 1.3-3.0 times of other inorganic flocculants.
   
3. It enjoys wide-range adaptability for different-temperature source water and a good solubility.
   
4. It is slightly corrosive and easy for operation.
   
5. The liquid product is suitable for automatic dosing. Furthermore, it will not block pipes over long-time usage.

1. Its purifying effect on low-temperature, low-turbidity and heavily organic-polluted raw water is much better than other organic flocculants , furthermore, the treatment cost is lowered by 20%-80%.
2.  It can lead to quick formation of flocculants (especially at low temperature) with big size and rapid precipitation service life of cellular filter of sedimentation basin.
3.  It can adapt to a wide range of pH value (5−9), and can reduce the pH value and basicity after processing.
4. The dosage is smaller than that of other flocculants.It has wide adaptability to the waters at different temperatures and different regions.
5. Higher basicity, lower corrosion, easy for operation,and long-term use of non-occlusion.

1. Mix the product (solid) and normal temperature water at the ratio of 1:2.5-1.3 [weight ratio] for about 30 minutes. After

dissolution of the drug, add 30-40 times of clear water for dilution or dilute to liquid according to the required concentration,
and then use [the greater the turbidity of the source water, the more clean water for secondary release].
 
2. When the turbidity of source water is 100-500mg / L, the dosage is 3-6mg. For specific dosing, a small test shall be conducted according to the water
quality, and the dosing amount shall be selected and then put into use.

Polyaluminum chloride is a water purification material, an inorganic polymer coagulant, and a polymer with a relatively large molecular weight and a relatively high charge of inorganic polymer produced by the bridge action of hydroxyl ions and the polymerization of polyvalent anions. Pharmacy. In form, it can be divided into two kinds: solid and liquid. The solids are divided into brown, beige, golden yellow and white according to different colors, and the liquid can be represented as colorless, transparent, yellowish, light yellow to yellow-brown.


The polyaluminum chloride having a content of aluminum oxide between 27 and 30 is mostly khaki-yellow yellow solid powder. These types of polyaluminum chlorides have relatively good water solubility, and in the course of dissolution, physicochemical changes such as electrochemical, agglomeration, adsorption, and precipitation eventually lead to [Al2(OH)3(OH)3] precipitation, thereby achieving the purpose of purification. In the use of polyaluminum chloride, without the need for other additives, floe formation is fast and thick, high activity, rapid precipitation, and a clear effect on high turbidity water purification.
