HomoPolymer Blufloc A-3515 Anionic Polyacrylamide Medium Molecular Weight Polymer
, CAS No. 9003-05-8 A-3515 Grade
Blufloc Homopolymer A-3515 Description:
- Anionic Polyacrylamide A-3515 grade (APAM) can be used widely for
Water treatment, oil drilling, Soil Stabilization and Cement
making.
- It is a water soluble Homopolymer formed from acrylamide (a
compound with the molecular formula C3H5NO) subunits.
- Anionic Polyacrylamide has a big range of high molecular weight
from 05-25 million, with an anionic charge density ranging from
10-60%.
- Our A-3515 grade has medium molecular weight, and medium charge
degree.
- It is most often used to increase the viscosity of water (creating
a thicker solution) or to encourage flocculation of particles
present in water.
- Soluble in water, safe, non-toxic, hydrolytic stability, is not
sensitive to the change of pH value, anti-chlorine. Harmless,
no-flammable and non-explosive, it can be stored at room
temperature, it cannot be placed in the sun. It is slightly acidic,
when skin contact, wash immediately with plenty of water.

Blufloc A-3515 Application Fields
1 | Raw water treatment | As flocculants for raw water sedimentation, thickening and
suspending removal |
2 | Sewage Water Treatment | water purification chemicals industrial wastewater treatment Used for acidophilic water systems. If matched with PAC, aluminum
sulphate, the effect will be excellent. |
3 | Industrial Wastewater Treatment | Dosing polyacrylamide can reduce the consumption of coagulant and
speed up sedimentation. |
4 | Coal Mine Washing | Coal washing tailing centrifugal separation
Sedimentation and filtration of coal powder and coal mud.
Highly improve the recovery rate of coal powder and the filtration
speed. |
5 | Chemical mudding agent | As chemical mudding agent for plugging water of dikes, ground
foundation, channels and the like. |
6 | Paper-making | Used as fixing agent, residency agent, filtration aid and paper dry
and wet intensity reinforcing agent in paper-making industry. |
7 | Sand Prevention Solidification | Dissolved into 0.3% concentration and cross-linking agent added. It
can be sprayed on desert to prevent and solidify sand. |
8 | Sugar and juice mills | For sugar and juice flocculation, sedimentation, clarification and
floatation |
9 | 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. |
10 | 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. |
Application and Dosage
The dosage range of varies from 0.2 - 3.0 ppm depending upon the
type of effluent and application. Advised to do jar tests for
evaluating the functioning and approximate dosage.
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 floc properly at this time and note the
sedimentation and clarity of top solution.
Procedure and precautions upon dispersion and dissolving
flocculants:
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.
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.
Dissolving concentration: Flocculants should be standardly be dissolved to 0.1-0.5%
concentration. It is also effective to start dissolving at a
slightly higher concentration, and then dilute the flocculant
mixture immediately before use.
Handling measures and precautions:
Proper human safety products such as Splash goggles, lab coat,
vapor respirator, gloves and boots should be worn while handling
and applying chemicals. Splashes on skin should be washed off with
water immediately. In case of splashing into the eyes, flush it
with fresh water and obtain medical attention. Should not be
injected. Please refer MSDS for more details.
