3Anionic Polyacrylamide MSDS Used in Dissolved Air Flotation Oily
Waste Water Treatment
Description:
- Blufloc AA5516 is High Molecular Weight Anionic Polyacrylamide,
powder form, good flocculation in water clarifying process, low
dosage, quick sedimentation.
- Suspended matter in raw water supplies is removed by various
methods to provide a water suitable for domestic purposes and most
industrial requirements. The suspended matter can consist of large
solids, settable by gravity alone without any external aids, and
nonsettleable material, often colloidal in nature. Removal is
generally accomplished by coagulation, flocculation, and
sedimentation. The combination of these three processes is referred
to as conventional clarification.
Flocculation is the process of bringing together the destabilized,
or "coagulated," particles to form a larger agglomeration, or
"floc."
Sedimentation refers to the physical removal from suspension, or
settling, that occurs once the particles have been coagulated and
flocculated. Sedimentation or subsidence alone, without prior
coagulation, results in the removal of only relatively coarse
suspended solids.

Steps of Clarification
Finely divided particles suspended in surface water repel each
other because most of the surfaces are negatively charged. The
following steps in clarification are necessary for particle
agglomeration:
- Coagulation. Coagulation can be accomplished through the addition
of inorganic salts of aluminum or iron. These inorganic salts
neutralize the charge on the particles causing raw water turbidity,
and also hydrolyze to form insoluble precipitates, which entrap
particles. Coagulation can also be effected by the addition of
water-soluble organic polymers with numerous ionized sites for
particle charge neutralization.
- Flocculation. Flocculation, the agglomeration of destabilized
particles into large particles, can be enhanced by the addition of
high-molecular-weight, water-soluble organic polymers, Blufloc
AA5516. Blfuloc increases floc size by charged site binding and by
molecular bridging.
Therefore, coagulation involves neutralizing charged particles to
destabilize suspended solids. In most clarification processes, a
flocculation step then follows. Flocculation starts when
neutralized or entrapped particles begin to collide and fuse to
form larger particles. This process can occur naturally or can be
enhanced by the addition of polymeric flocculant aids.
