POLY ALUMINIUM CHLORIDE (PAC)
CAS No.:1327-41-9
POLY ALUMINIUM CHLORIDE (WHITE, ROLLER OR SPRAY DRYING)
Poly aluminium chloride, abbreviated as pac, is a new type, high-effective inorganic polymer flocculam. it is the product between alcl3 and al(oh)3,polymerized by building a briage through hydroxyl. its chemical formula is [al2(oh)ncl6-n]m, in which m<10,n<5. pac is easily dissolved in water and has a strong bridge-building adsorption performance.during the process of hydrolysis, there are physial and chemical changes such as electric chemistry, condensation, adsorption and presipitation, etc.
Compared with other coagulants, this product possesses the following advantages.
1. Wider application, better water adaptation.
2. Quickly shape big alum bubble, and with good precipitation.
3. Better adaptation to PH value(5-9), and little declining range of PH value and alkalinity of water after treatment.
4. Keeping stable precipitation effect at lower water temperature.
5. Higher alkalization than other aluminium salt and iron salt, and little erosion to equipments.
