Wastewater Treatment Agent Poly Aluminum Chloride - China

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 state.

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


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


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

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 concentration.

3. The original solution and the diluent are

less corrosive than other inorganic



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 stored.

PAC Packaging and Storage

1. Packaging: plastic woven bag outside,

plastic film inside

2. Net weight: 25kg per bag or according to

customer’s requirements.

3. Never put PAC together with toxicity

substance and other chemical agents including

same product made by different producer.

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


7. Solid PAC should be dissolved before

application and the related equipment must be

made from corrosion-resistant materials.

8. Valid time: liquid PAC half year ;solid

PAC( one year)
