Description:
Cationic Polyacrylamide, a water-soluble polymer with medium-high molecular weight supplied as a free-flowing granular powder. It is a synthetic chemical that can be tailored to fit a broad range of applications such as dewatering, flocculation, clarifying, etc.
Polyacrylamide, or PAM, is an organic polymer formed from acrylamide subunits. Initially, it is produced with a simple, repeating, linear chain structure, but can be modified to form highly structured, branched, and cross-linked variants.
It has many uses throughout a wide range of industrial processes, but one of the main purposes is in the separation of solids/liquids in the municipal and industrial wastewater sectors.
As part of the manufacturing process, the ionic characteristics of the polymer can be manipulated to achieve varying degrees of anionic (negative charge) or cationic (positive charge) qualities and non-ionic (minimal charge), which is a key factor during the polymer selection process.

Application Fields:
1. Well Drilling Mud Additives:
In oilfield, as mud additives to increase the viscosity of water to improve the effectiveness of the water flooding
process, especially for temperature tolerant and salt resistance.
2. Industrial Wastewater Treatment:
Dosing polyacrylamide can reduce the consumption of coagulant and speed up sedimentation.
3. Textile Auxiliary Agent:
PAM can be added with some other chemicals to prepare chemical grout, is used to starch textiles, can improve
the adhesive property, penetrability and desizing performance, enables the textile to have electrostatic prevention
performance, reduces the desizing rate, and reduces the starch mixing spots, cloth machine breaking efficiency,
and falling objects.
4. Paper-making:
PAM can be used as fixing agent, residency agent, filtration aid and paper dry and wet intensity reinforcing agent
in paper-making industry.
5. Mine Washing:
PAM can be used in coal washing tailing centrifugal separation, for sedimentation and filtration of coal powder
and coal mud, and can improve the recovery rate of coal powder and the filtration speed.
6. Sewage Water Treatment:
When sewage water systems are acidophilic, it is more suitable to select nonionic-polyacrylamide, the product can be matched with PAC, aluminium sulphate and the like, and it has the best effect
in water treatment.
7. Metallurgical Mineral Dressing:
It can be used in floatation and smelting of Zinc, manganese and copper mines, its leachate and slag can be
added into PAM to improve the separation efficiency.
8. Sand Prevention and Solidification:
The polyacrylamide is dissolved into 0.3% concentration, cross-linking agent is added, and the product can be sprayed on desert to prevent and solidify sand.
9. Chemical mudding agent:
Polyacrylamide can be used as chemical mudding agent for plugging water of dikes, ground foundation,
channels and the like.
10. Oil field profile controlling and water-plugging agent:
The product can be matched with lignocellulose, a certain amount of chemical adhesive can be added, and the
product can be used as oil field profile controlling and water-plugging agent.
11. Soil humectants:
It can preserve water and solidify sand for soil and can play a role of humectant on slope grass planting, tree
planting, and sand solidification and dust prevention of soil.
Application Methods:
| 1 | Dissolving concentration: | Polyelectrolyte/flocculant powder should be standardly be dissolved to 0.1-0.5% concentration. |
| 2 | Dissolving time: | The time required to dissolve the flocculant varies according to the type of flocculant, water quality, temperature and agitation. However, most flocculants generally require around 1 hour of agitation to completely dissolve the powder. Incomplete mixture of flocculant or lumping may inhibit the performance of the flocculant. |
| 3 | Agitation speed: | The ideal revolution of the agitator is between 200-400rpm. A high speed agitator operating without reducing the revolution of a motor is not advised, since it may cut the molecules of the flocculant. An ideal agitator motor should be of 1HP for a 1-2m3 mixing tank. |
| 4 | Application and Dosage: | The dosage range of varies from 1 - 3.0 ppm depending upon the type of effluent and application. Advised to do jar tests for evaluating the functioning and approximate dosage. |
| 5 | Jar Test: | Put a sample of effluent in a beaker and add it as designated, agitate for 1 minute at 100-120 rpm and then slowly agitate at 60rpm. Determine the flocs properly at this time and note the sedimentation and clarity of top solution. |
