Description: Wastewater Flocculation
Polyacrylamide, or PAM, is a highly water-soluble polymer used in a
variety of industries, including paper making, chemical, petroleum,
textile, metallurgical, and environmental protection.
Non-ionic polyacrylamide (NPAM) is a water-soluble polymer made up
of acrylamide subunits (C3H5NO).
NPAM has a high molecular weight range of 5-8 million and an
anionic charge density of 0-10%.
Our N830 grade has a low to medium molecular weight and low charge
degree.
It is commonly used to increase water viscosity or encourage
particle flocculation.
Because of the polar groups on its molecular chain, NPAM can adsorb
suspended solid particles in water, bridge between particles, or
use charge to condense particles into larger flocs. This
accelerates particle settlement, clarifies solutions, and promotes
filtering.
NPAM is mainly used for industrial wastewater treatment, including
flocculation, sedimentation, and clarification of iron and steel
plant wastewater, electroplating wastewater, wastewater metallurgy,
coal washing wastewater, and sludge dewatering. It can also be used
for drinking water purification in sugar and juice mills.
NPAM is soluble in water, safe, non-toxic, and hydrolytically
stable. It is not sensitive to changes in pH or chlorine and can be
stored at room temperature. It is slightly acidic, and if it comes
into contact with skin, it should be washed off immediately with
plenty of water.

Application Fields:
Oil-displacing Agent of Oil Field Tertiary Oil Recovery:
It can adjust the rheology of filled water, increase the viscosity
of driving liquid, improve water drive wave and efficiency, lower
water phase permeability in ground layer, and enable water and oil
to flow forward at even speed. Its effect is that it is mainly used
in tertiary oil recovery of oil fields in the aspect oil
production, and raw oil of about 100 to 150ton more can be produced
through filling the macromolecule polyacrylamide product one ton.
Well Drilling Mud Raw Materials:
In oil field exploration and development and exploration of
geology, water and coal, it is used as adhesive of well drilling
mud raw materials, can improve the service life of drill bits,
improve the drill speed and drilling footage, and reduce plug in
replacing drill, and has prominent well slough preventing effect,
and it can be used as fracturing fluid of oil fields or plugging
agent of controlling profile and plugging water.
Flocculant:
The polarity gene adsorbs the solid particles dispersed in water,
bridges between the particles and formats the large aggregates,
sedimentation and separates of water, flocculates detritus and clay
in drilling fluid.
Dispersant:
In the drilling mud treatment, this product can improve the
lubricity and stability of the mud to reduce the water loss,
prevent sticking effectively, increase drilling efficiency.
Blocking Agent:
The product can generate cross linking under the effect of Al3+, Fe
3+, Ca2+ and other ions, a part of high molecular compound is
changed from linear shape into body shapes. The product is not
watersoluble, and can be adsorbed on the borehole to block ground
layer gaps and topreven the leakage of drilling fluid.
Lubricant:
The product can be absorbed on the surface of metal or clay
particles to form liquid film to change friction on the solid
surface into liquid frication, thereby lubricating drill bits and
drills, lowering the mud cake frication coefficient, and reducing
underground accidents.
Fluid Loss Additive:
The hydrolysis degree is higher, the hydration group on the
molecular chain is more, the hydration is better, and it changes
from flocculant into fluid loss additive. Drilling mud should be
treated to keep cake’s permeability as low as possible in order to
maintain a stable borehole and to minimize filtrate invasion, and
damage to the pay zone.
Shale Inhibition Agent:
The multipoint adsorption of polymer formats to the crisscross
membrane macromolecules, plays a role of enhancing the stability of
borehole .
Competitive Advantage:
1 | Economical to use - lower dosage levels. |
2 | Easily soluble in water; dissolves rapidly. |
3 | Faster sedimentation, better flocculation. |
4 | Non-pollution (no aluminum, chlorine, heavy metal ions etc.). |
5 | 10 years manufacturing experience, with more than 20 technical
engineers |
Application Methods:
1 | Dissolving concentration: | Polyacrylamdie (polyelectrolyte/flocculant) 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 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 Kraft or PE bags with inner plastic bags, with each bag
containing 25kgs, or 750kgs net big bag.
