Polyaluminium 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.

Features:
This product shows the flowing features compared with other coagulants:
1. Wide application, and adapt to most kind of water.
2. Free form adding other auxiliary agent, lower dosage than other inorgnic coagulant,
and lower water treatment cost.
3. Easy to quickly shape big alum fume, and showing good setting behavior.
4. Adapt to wide PH  # 118alue ( 5-9) , superior adaptability and good water treatment effect for high
tempreature and high turbid waste water, low tempreature and low turbid water, and organic pulluted water.
5. Keeping good precipitating effect even at low temperature.
6. Alkalization degree is higher than other aluminium and iron salts, and have little erosion effect to equipments.

Application:
Mainly used for purifying treatment of drinking water, production waste, industrial wastewater.

Usage:
1. 1. Solid PAC should be added after dissoved in water, and the dilution
ratio is generally 2-20% ( weight percent) ;
2.The dosage is generally 1-15 g solid PAC per MT raw water, and can be decided
according to actual experiment according to different water quality and turbidness.

Cautions:
1. Solid PAC can’ t be stored together with other chemical reagents.
2. Solid PAC should be stored in dry and ventilated place with the storage period of 2 years,
and its performance won’ t be changed after affected with damp
