Poly aluminium Chloride (PAC
.Poly aluminium Chloride is short for PAC, is a new highly efficient inorganic polymer

flocculat, it is between ALCL3 and AL (OH) 3 between the hydrolysis product, by hydroxyl and bridging polymer, its molecular formula: [Al2 ( OH) nCl6-n • xH2o] m (m ≤ 10, n = 1 ~ 5)

PAC soluble in water easily, there is a strong bridge adsorption, in the hydrolysis process, accompanied by the electrochemical, cohesion, adsorption and precipitation and other physical and chemical changes.

The product is mainly used for drinking water purification and industrial wastewater treatment, such as radioactive substances, lead (Pb + +) chromium (Cr + + +) highly toxic heavy metals and fluorine (F) water and so on.

In addition, in precision casting, papermaking, leather, etc. are also widely

When dealing with drinking water, plus the general liquid dosage 5-30g/m3, plus solid dosage 1-15g/m3 treatment of domestic sewage and industrial wastewater, generally increase the liquid dosage 20-100 g/m3, solid increase dosage 10-50g/m3, water use should be based on the COD, PH, SS and other indicators. By testing to determine the appropriate dosage increase.

Liquid the poly aluminium chloride Uses the polyethylene plastic barrel packing, each barrel only heavy 25kg, 50kg or 200kg.

Uses the double-decked bung, Insidecovers buckles strictly, Outsidecovers tightens.

When the user needs, the liquid gathers the aluminum chloride also serviceable stores the tanker ships.

Solid product with double-decked packed in bags, each bag of only heavy 25kg, the inner layer is the plastic bag, outside the level weaves the bag for the plastic.

This product should store up in ventilates in the dry storehouse, strictly prohibits the rain drenching, being affected with damp.

Polyaluminium Chloride Technology

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.

THE PROCESS

The production process for polyaluminium chloride is including the following reaction steps:

Feeding

Reaction

Filtration

Depending on reaction conditions products with different characteristics are obtained.

For the production of polyaluminium chloride 9% special auxiliaries and catalysts are used.


Detailed Product Description

PAC production line:
high temperature reactors, pipeline, valves can manufacture high quality PAC products.


PAC production line

With the advanced production process technique, under the condition of high temperature, high pressure, using the super materials to manufacture the high quality PAC products with the lower Insoluble5 and heavy metal content, can be suitable for drinking water treatment and other special demand.

Poly-aluminium Chloride (PAC):

Poly-aluminium Chloride, short for PAC, is a new type high performance inorganic macromolecule flocculating agent.

It's hydrolysis product of AlCl 3 and Al(OH)3 , and polymerized & bridged through hydroxyl group. And its molecular formula is [Al2(OH)n Cl6 -n • xH2O] m (m ≤ 10,n=1-5)

The Poly-aluminium Chloride is freely soluble into water, and has quite strong adsorptivity, many physic & chemical reaction, such as sedimentation, adsorption, agglutination, and electric chemistry, happen during hydrolysis process.

This product is mainly used in purify of drinking water and treatment of industry waste water, such as the radioactive material, leady (Pb++) chromate (Cr+++) high toxicity heavy metal and fluoride (F) waste water.

Furthermore, it also widely used in precision casting, papermaking, tanning and some other fields.

Using and packing method

1. When use solid product, make 5-10% solution first, then dilute to request concentration; during the dissolution, add the water and mix slowly, the diluted solution should be used up in 24 hours to avoid hydrolysis and reduce the effect.

The dose quantity of this product is based on water resource haziness and purifies facility, the coagulating sedimentation test is needed to ensure the best dosing quantity.

2. Use the polyethylene plastic barrel to store liquid Poly-aluminium Chloride, the net weight of each barrel is 25kg, 50kg or 200kg.

And covered with double cover, fasten the inner cover, screw the outer cover.

The liquid Poly-aluminium Chloride can also be transferred by tank vehicle.

The solid Poly-aluminium Chloride is packed by double bag, the net weight of each bag is 25kg, inner bag is plastic bag, and outer bag is plastic basket bag.

The product should be stored in dry, airy warehouse and avoid drench and breathing.
