Properties:
Poly-aluminium chloride (PAC) is a kind of high efficiency inorganic highmolecular coagulant. Poly-aluminium chloride (PAC) is the product between AlCl3 and Al(OH)3.
1. Quick moulding, good activity and good fitrabilitiy.
2. Alkalescence auxiliaries are not necessary.
3. Wide adaptive PH value and wide use.
4. Little salt content in the water treated.
5. Can remove the pollution of heavy metal and radioactive substance.
6. High active ingredients, convenient for storage and transportation
Applications:
1. It is an Aluminium based coagulant used in water treatment, paper sizing and affluent treatment.
2. It has wide uses in purifying water,e.g.
3. It is used in purify drinking water, domestic wastewater
4. It is used in purify industrial water, industrial waste, recirculated water,etc,
5. It is used in paper making,dyeing and beaching,cement harderner.,bond,glycerin refinement, sugar solution refinement, etc.
6. It is also used in oilwater separation in oil refining industry.
Packing:
25kg P.P Woven bags
Storage:
1. Store in a cool place out of direct sun light and in well ventilated area.
2. Store away from oxidizing agents and foodstuffs
3. Prevent severe overheating as overheating may produce hydrogen chloride gas.
