Description:
The EA-6518 grade of Anionic Polyacrylamide Emulsion (APAM) is a
water-based polymer with a high molecular weight and medium charge
degree. This type of APAM has a molecular weight range of 16-25
million and an anionic charge density of 10-60%.
Its primary uses include increasing water viscosity and promoting
the flocculation of particles in water. The presence of polar
groups on the molecular chain allows for the adsorption of solid
particles suspended in water, which can bridge between particles or
through charge and create larger flocs, thus accelerating particle
settlement, promoting water clarification, and enhancing filtering
effects.
The EA-6518 grade of APAM is mainly used for various industrial
wastewater treatment applications, such as flocculation
sedimentation, clarification, and sludge dewatering. It is commonly
used in wastewater treatment for iron and steel plants,
electroplating wastewater, metallurgical wastewater, coal washing
wastewater, as well as in sugar and juice mills. Additionally, it
can be used for drinking water purification treatment.
This water-soluble polymer is safe, non-toxic, hydrolytically
stable, and not sensitive to changes in pH value or chlorine. It is
harmless, non-flammable, and non-explosive, making it suitable for
storage at room temperature. However, it should not be exposed to
sunlight. It is slightly acidic, and if it comes into contact with
skin, it should be washed immediately with plenty of water.

To increase the viscosity of water and improve the effectiveness of
the water flooding
process. |
8 | 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. |
9 | Textile | Textile Sizing, as a kind of composition for chemical grout, starch
textiles
Highly improve the adhesive property, penetrability and desizing
performance, enable the textile to have electrostatic prevention
performance, reduces the desizing rate, and reduces the starch
mixing spots, cloth machine breaking efficiency, and falling
objects. |
Competitive Advantage:
1 | Economical to use - lower dosage levels. |
2 | Can be used directly, dont need to mix. |
3 | Non corrosive of suggested dosage, economical and effective at low
levels. |
4 | Can eliminate the use of alum & further ferric salts when used as
primary coagulants. |
5 | Reduction in sludge of dewatering process system. |
6 | Faster sedimentation, better flocculation. |

engineers |
Application Methods:
1 | 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. |
2 | Jar Test: | Put 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. |
Package and Storage:
Packed in 25kg plastic drums, or 1000kg IBC drums
Stored in original packaging in cool and dry place, away from
sources of heat, flame and direct sunlight.
