    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)
