Polyaluminium Chloride
Polyaluminum Chloride (PAC) or also known as Alkaline Aluminum Chloride is a water-soluble inorganic macromolecule polymer that is intervenient with ALCL3 and AL(OH)3. Its molecular formula is [AL2(OH)NCL6-NLm]. The m in the formula represents Polymerization and n for Neutralization. It is a type of vitreous solid with colors varying from yellow, light yellow, dark brown, and heavy gray and has a strong bridgework absorbance.
The basic difference between PAC and other traditional products is that the traditional ones are electropositive with small molecular and crystalloids. PAC has the structure of many Hydroxy Polymers with various different shapes. Its strengths are high speed deposition, wide range of PH value, does not cause harm to equipment, a great water purifier, clears up SS, COD, BOD, and heavy metal ions like AS with high efficiency.
Pac is commonly used in drinking water, waste water, and industrial water.
Methods on how to use Pac is as following :
1: add the solid PAC into water with the percentage of 1:3, then dilute it to the consistence you wanted with 10-30 times the amount of water
2,According to the turbidness of the sewage water, decide the best quantity of Pac to put into the water. When the turbidness of the sewage water is 100-500mg/g, it is better to add 10-20kgs per kiloton.
Package, transport then store.
1,the liquid product is packaged in a plastic barrel or a plastic trough, and stored either a cement trough or plastic trough.
2,the solid product is packaged in a plastic bag with double layers and sealed well, so that the plastic pellicle bag is on the inside and the plastic intertexture is on the outside. The net weight per bag is 25kg.
3,the solid product can absorb the water easily, but there is no effect in using Pac because of absorbing. we suggest that you store it in a place that is both dry and ventilated place.
4, warning: this product can not be stored together with other toxic and/or harmful chemicals.
