Polyacrylamide plays a crucial role in enhancing the Dissolved Air
Flotation (DAF) process's efficacy, particularly in treating
wastewater with high levels of suspended solids, oils, and greases.
Aids Flocculation: In the DAF process, polyacrylamide is often used as a flocculant
to bind small particles and impurities together. This action
creates larger flocs that can be more easily separated from the
water.
Increases Flotation Efficiency: The larger flocs formed through the use of polyacrylamide rise to
the surface more effectively when air is dissolved into the water
under pressure. As the pressure is released, the air comes out of
the solution in the form of microbubbles that attach to the flocs,
making them float to the top.
Improves Sludge Blanket Formation: The use of polyacrylamide enhances the formation of a concentrated
sludge blanket on the surface of the water in the DAF unit. This
sludge blanket can be removed more efficiently, leaving cleaner
water behind.
Optimizes Treatment Parameters: By using polyacrylamide in DAF, the need for adjustments in
treatment parameters such as coagulant dosage and pH level can be
reduced, leading to an optimized process.
Polymers used in Water Purification
Polymers are used in water purification to remove impurities such
as suspended solids, bacteria, viruses, fungi, algae and organic
matter. Polymers can be used as coagulants or flocculants.
Coagulants are used to destabilize particles and form larger
aggregates that can be removed by sedimentation or filtration.
Flocculants are used to increase the size of particles so that they
can be removed by sedimentation or flotation. Polymers used in
water purification include polyacrylamide (PAM), polyethyleneimine
(PEI), polyvinyl alcohol (PVA), polyvinylpyrrolidone (PVP), and
polyethylene glycol (PEG).

How to Use Blufloc Polyacrylamide?
Application and Dosage: The dosage range of flocculants varies from 0.2 - 3.0 ppm
depending upon the type of effluent and application. It is always
advised to do a jar test for evaluating the functioning and
approximate dosage.
Jar Test: To perform a 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 floc properly at this time
and note the sedimentation and clarity of the 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. The 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 dissolved to a standard concentration of
0.1-0.2%. 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 the skin should be washed off
with water immediately. In case of splashing into the eyes, flush
with fresh water and obtain medical attention. Flocculants should
not be injected. Please refer MSDS for more details.
