Supply Polyaluminium chloride (PAC) production line

Polyaluminium chloride (PAC) is increasingly used for water treatment. Against the conventional use of aluminium sulphate (alum) it is showing distinct advantages.

A polyaluminium chloride plant is an investment opportunity with attractive returns in a growing market.

We have the capability of design and producution for PAC manufacture, can supply PAC manufacturing production line, including manufacturing capacity of 2000 MT, 5000 MT and 10000 MT PAC annually, and we provide design, technical process and complete plants and equipment.

Raw materials:
Aluminium hydroxide powder: AL2O3, ≥, 58%; PH value, 7-8;
Hydrochloric acid: HCL, ≥22%;
Aluminium calcium powder: AL2O3, 48%; CaO, 30%;
Bauxite: AL2O3, 28-32%; CaO, 30%.

For PAC production equipments, there are two kinds of manufacturing process, roller dried process and spray dried process. Roller dried process is more environmental polluted and produce more waste air, dust and residue, most of China's PAC enterprise adopt this process. Spray dried process is less environmental pollted and produce higher quality PAC, and only limited enterprise adopt this process at present.

Features of spray dried process:
The features of pressure type spray dried method is determined by the operating principle of pressure type atomizer. The output product after pressure type spray dried process is porous fine particle or hollow fine particle, which show the features of superiors dustproof and flowing property. Owing to its bigger contact area between itself and surrounding water than other powder products, it shows better wettabiliy and quicker water purifying speed. Spray granulation is to dry polyaluminium chloride and atomize to be minute particle simultaneously. Polyaluminium chloride is water soluble substance and shows features of good thermal stability and high solubility. Polyaluminium chloride solution with 40-50% solid content on drying is introduced to high pressure pump, atomized in atomizer of dryer to be minute fogdrop which is then dried to be granular products. Dehydration and granulation are made simultaneously in this process.

Different production process:
Spray dried process:
liquid process –Plate-and-frame pressure filtration- Spray tower drying -Finished product

Roller dried process:
Liquid process- free setting- Roller drying – Finished product.


Manufacturing technological flow:
Aluminium hydroxide powder and Hydrochloric acid, or bauxite and Hydrochloric acid→ reaction tank→ sedimentation tank→ reaction tank→ sedimentation tank→ dryer→ PAC finished products
