Flocculation Coagulation Poly Aluminum Chloride Solution - China

price: contact company for price

PAC (Poly Aluminum Chloride)

PAC is a kind of new inorganic polymer flocculate of high

efficiency. It is produced by advanced production process

and it is formed by polymerization of good raw materials. It

can be divided into solid state and liquid state. The solid

PAC can be brown, yellow or white. There is a big difference

in application and production technology among each PAC of

those different colors. It has a lot of advantage, such as

less inpurity, higher molecule weight and better

condensation effect.

PAC State

PAC is divided into two states: solid state and liquid


Liquid PAC is the form before drying. Its advantage is no

attenuation, simple operate and low price. But it should be

transported by tanker car, resulting in higher

transportation cost.

Solid PAC is the form after drying. Its advantage is that it

doesn’t need a tanker car and it is easy to transport while

its disadvantage is that it needs attenuating and this

increases the labor intensity.

Product Performance

1. It has a large number of stable polynuclear hydroxy

aluminum complexes of positive charge, which is helpful for

flocculation and sizing treatment. The water processed by

PAC is better than that processed by Aluminum Sulfate.

2. Lower basicity consumption, lower dosage and lower cost.

3. It is available to water with a wide PH range (5.0-9.0).

4. It is less corrosive and it is easy to operate.

PAC Advantage

White PAC is one of the star products in water treatment

agent series. It is a composite efficient product that

shares a lot of advantage with common PAC, spray PAC and

paper-making PAC.

Basic differences between PAC and traditional inorganic

coagulants lie in their different structures. The

traditional inorganic coagulants’ structure is low-

molecular-weight crystalline salt while PAC’s is multiple

Carboxyl Complex. PAC can make flocculations fast

precipitate and it can effectively remove heavy metal ions

including SS, COD, BOD, As and Hg from water. PAC is

applicable to a wide PH range and it is not corrosive to

pipe equipment. All of these advantage make PAC popular in

drinking water, industry water and waste water treatment.

Differences between PAC of Different Colors

In general, PAC has three colors: white, yellow and brown.

White PAC is called high-purity white PAC without iron or

food grade white PAC. It is of the top quality. Compared

with others, its raw material is superior aluminum hydroxide

powder and hydrochloric acid and it adopts spray drying

technology, which is the most advance technology. White PAC

is widely used in many industries, such as paper sizing,

sugar’s decoloring & clarifying, tanning, medicine,

cosmetic, precision casting and water processing industry.

Yellow PAC has two solid forms: flake and powder. Its raw

materials are calcium aluminate powder, hydrochloric acid

and bauxite. Yellow PAC is mainly used to process waste

water and drinking water. When it is used for drinking

water, the materials should be aluminum hydroxide powder,

hydrochloride acid and some calcium aluminate powder. Its

manufacture technology is plate-frame filter pressing and

spray drying method. What’s more, yellow PAC can also be

made by roller drying or spraying tower drying. Our country

pays much attention to heavy metal percentage in the

drinking water, therefore, no matter from raw material or

production technology, yellow PAC is better to process

drinking water than brown PAC.

Brown PAC is made from calcium aluminate, hydrochloric acid,

bauxite and iron powder. It is made by roller drying and it

is adapted to waste water processing. The color is brown

because there are some iron powders inside. The more iron

powder is, the deeper color will be. If iron powder is

beyond the indicator, it will be called PAFC, which plays an

important role in waste water treatment.

Usage and Notes


1. The test should be done before application according to

the water quality to choose a best point where the purifying

result is the best but with the lowest dosage.

2. The water should be added to produce 10-25% PAC solution

when the solid PAC is used. Then the solution should be

stirred continually until it is attenuated to the proper


3. The original solution and the diluent are less corrosive

than other inorganic flocculants.


When using the solid PAC, users can add some water to get

the 5%-15% alumina solution according to actual demands,

which depends on the process designs and working conditions.

Then the final solution can be put by chemical dosing system

or it can be directly put into the water to be processed.

The specific dilution method is as follows: First, the clean

water should be poured into the dissolving tank and then

stirred. Secondly, the PAC powder should be put into the

clean water and then be stirred until it is totally

dissolved. Workers should wear goggles, rubber gloves,

overalls to avoid directly contacting their skin with the

product. The final solution can be used directly or be

3. Never put PAC together with toxicity substance and other

chemical agents including same product made by different


4. Storage place should be an indoor place that is dry,

ventilated and cool .

5. Be loaded and unloaded quietly.

6. Liquid product should be transported by tank cars and

pail packs. It can be used directly.

7. Solid PAC should be dissolved before application and the

related equipment must be made from corrosion-resistant
