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

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.

Different production process
Spray dried process:
liquid process –Plate-and-frame pressure filtration- Spray tower drying -Finished product
Generall dried process:
Liquid process- free setting- Roller drying – Finished product
Different product constitutive property and different treated water quality effect
The three primary indicator of PAC are Al2O3 content, basicity and water soluble substance.
1. In the spray drying process, nozzle uniformly spray mother liquid in the drying tower, which ensure Al2O3 content is uniformly and stable and easily controlled within target zone, improve adsorptivity of colloidal particle and make coagulation and flocculation effect, which is unmatched by other drying process.
2. Basicity namely polymerization degree directly influence water treatment effect. Adoption of pressure type particle spray drying process can increase product polymeriztion degree in the situation of maintaining activity of mother liquid. Furthermore, basiciy can adjusted according to different water quality for product manufactured through spray drying process, whereas product manufactured through roller drying process is liable to break polymeriztion degree, have only very small basicity range, and adjust to limited water quality.
3. Owing to adopting plate frame pressure filtration technology, solid water nonsoluble substance are controlled within 0.3 and liquid water nonsoluble substance within 0.1, which ensure the smoothness of clients pipe, and this is unattainable by free setting process.
Different composite cost
Products manufactured through spray drying process show features of high stability, adaptation to wide water area, quick hydrolysis speed, strong absorptivity, big flocs, quick precipitation, low turbidity out of water and superior dehydration property. Spray drying products are needed less than other products for the treatment of same water quality, and especially for seriously polluted water, Spray drying products are only needed half less than roller drying products, which can not only decrease worker’s labor intensity, but also reduce clients’ water cost. Besides, spray drying products can avoid water accident, and are more safe and reliable for drinking water.
NOTE: As customer have special requirement for quality, we can carry out production according to the index that customer offers.
PACKAGE AND STORAGE
1. The solid product is packaged in 25kg polypropylene woven bags with inner plastics bags, 20MT/FCL without pallet.
