Cationic Poly Acrylamide (CPAM)


Cationic Poly Acrylamide(CPAM) is a linear polymer compound. Because it has a variety of active groups, it can be affinity with many substances and form hydrogen bonds. Mainly flocculates negatively charged colloids with the functions of removing turbidity, decolorization, adsorption, adhesion and other functions. It is suitable for organic colloid content in industries such as dyeing, papermaking, food, construction, metallurgy, mineral processing, pulverized coal, oil fields, aquatic products processing and fermentation. Higher wastewater treatment is particularly suitable for the dewatering of municipal sewage, municipal sludge, paper sludge and other industrial sludge.

※ Appearance: White powder or granular appearance

※ Solid content: ≥90%

※ Molecular weight: 800-1200 million

※ Insoluble matter: ≤0.5%

※ Residual unit: ≤0.05%

※ Cation degree: 10-90 %

※ Dissolution time: ≤60 minutes

The Scope of Application:
 For sludge dewatering depending on the sludge properties, the corresponding grades of CPAM products can be used. The sludge can be effectively dewatered before the sludge enters the pressure filtration. When the sludge is dewatered, large flocs and non-sticky filter cloths are produced. Scattered, thick mud cake flow, high dewatering efficiency, mud cake moisture content below 80%.

2) For the treatment of domestic sewage and organic waste water, cationic poly acrylamide products are all positive in compatibility or alkaline medium, so that the flotation and sedimentation of sewage with suspended particles in the sewage with negative charge is very effective. Such as the production of grain alcohol wastewater, papermaking wastewater, municipal wastewater treatment plant wastewater, brewery wastewater, monosodium glutamate wastewater, sugar wastewater, organic high wastewater, feed wastewater, textile printing and dyeing wastewater, using cationic poly acrylamide than anion, Non-ionic poly acrylamides or inorganic salts are several or more times more effective because such wastewaters are generally negatively charged.

3) The flocculating agent for tap water with river water as the source of water is less in amount, effective, and low in cost, especially in combination with inorganic flocculants. It will become the tap water for the Yangtze, Yellow and other river basins. The plant’s efficient flocculant.

1).Through a small test to determine the best model, and the product’s optimal dosage.

2). The product is formulated as an aqueous solution with a concentration of 0.2% (referring to the solid content), preferably neutral water without salt.

3). Dissolved water, the product evenly sprinkled into the stirring water, appropriate heating (<60 °C) can be accelerated into a solution (stirring time is about 40 minutes).

4). Solid products should not be sprinkled on the floor to prevent the product from becoming slippery after absorbing moisture.

5). The preparation of PAM aqueous solution should be carried out in enamel, galvanized, aluminium or plastic barrels. It cannot be prepared and stored in iron containers.

6). When dissolving, care should be taken to add the product evenly and gradually to the dissolver with stirring and heating measures. The solidification should be avoided. The solution should be prepared at a suitable temperature, and mechanical shearing should be avoided. Mixer 60-200 rev / min, otherwise it will lead to polymer degradation, affecting the use of effects.

7). The PAM solution should be ready for use. When the solution is left for a long time, its performance will gradually decrease depending on the water quality.

8). After adding an aqueous flocculant solution to the suspension, if the stirring is vigorously performed for a long time, the formed flocks will be destroyed.

Packaging, Storage and Handling and Precautions:
Solid products are packed in paper bags, lined with plastic bags, 25kg per bag, and can also be packaged according to customer requirements.

This product has hygroscopicity, should be sealed and stored in a cool dry place, the temperature is lower than 35 °C, the effective storage period is 2 years.

Poly Aluminum Chloride (PAC)


Poly Aluminium Chloride (PAC), is a water-soluble inorganic polymer between AlCI3 and Al(OH)3, its general formula is [Al2(OH)nCl6-nLm], of which m represents the degree of polymerization and n represents the degree of neutrality of PAC products. This product has strong bridge adsorption performance. During the hydrolysis process, condensation, adsorption, precipitation as well as other physical and chemical processes also occurs at the same time.

The fundamental difference between poly aluminium chloride and traditional inorganic coagulants is that the traditional inorganic coagulants is low molecular crystal salt, but the structure of poly aluminium chloride is composed of polycarboxyl complex with variable morphology, it has high speed of flocculating and precipitating, suitable for wide PH range, no corrosive to pipeline equipment, obvious water purification effect, it can effectively remove chromaticness, Suspended Solids(SS), Chemical Oxygen Demand(COD), Biochemical Oxygen Demand(BOD) and such heavy metal ions as arsenic and mercury in the water. This product is widely used in drinking water, industrial water and wastewater treatment field.

Poly Aluminum Chloride (PAC)


PAC is certainly not a solitary item, yet a whole range of flexible inorganic polymers. PAC’s are portrayed by two essential numbers: their quality (as a rule in % alumina, or Al2O3), and their basicity. Basicity gives a general thought of the sum or level of polynuclear material in the PAC. At the low end of the basicity scale is ACS, with 0% basicity (which implies it’s anything but a PAC). The least basicity business PAC’s are about 10%; most PAC’s are in the medium to high basicity extend (50-70%). At the highest point of the scale is aluminum chlorhydrate (ACH): at 83%, it is the most elevated stable basicity PAC Pakistan accessible. (ACH is just an exceptional types of PAC – progressively about ACH in the following area).

PAC’s can offer various favorable circumstances over customary coagulants, for example, alum or iron salts. Since Poly Aluminum Chloride are pre-killed and have a higher charge thickness than customary coagulants, they coagulate through a progressively proficient instrument, called charge balance. This enables PAC’s to be compelling at lower portions than alum or iron salts, when one thinks about the real metal being added by the coagulant to the framework. Coming about advantages can include:

Less pH misery and alkalinity consumption, diminishing lime or harsh prerequisites

Diminished concoction ooze volumes.

Slop thickness is expanded.

Improved outcomes in higher pH frameworks.

Better execution in virus water.

What’s more, since PAC does work so any other way, there are numerous applications where it will give completed water quality that the customary coagulants can’t accomplish.

GEO comprehends the connections between basicity, alumina content and the manner in which a PAC will perform. We additionally have the capacity to deliver Poly Aluminum over the whole range of basicity; our standard line incorporates low, medium, high and greatest basicity items. Consolidate our applications and assembling ability, and GEO can locate the ideal PAC item for you.
