Description:
Polyacrylamide is used to coagulate or flocculate solids in a
liquid. This makes them useful in water treatment applications. Polyacrylamide is a linear polymer, the product is mainly divided
into dry powder and colloidal two forms. According to its average
molecular weight, it can be divided into low molecular weight
(<1 million), medium molecular weight (2 ~4 million), and high
molecular weight (>.7 million). Its structure can be divided
into non-ionic, anion, and cationic. Water disintegration (HPAM) of
anion type. It generates good flocculation and can decrease the resistance
between liquids. It is most often used to increase the viscosity of water (creating
a thicker solution) or to encourage the flocculation of particles
present in water and allow rapid settlement of finely suspended
solids. |

Description and Purpose of Polyacrylamide
The products have been widely used in papermaking, mineral
processing, oil extraction, metallurgy, building materials, sewage
treatment, and other industries. As a lubricant, suspension agent,
clay stabilizer, oil displacement agent, water loss-reducing agent,
and thickening agent, polyacrylamide has been widely used in
drilling, acidification, fracturing, water plugging, cementing,
secondary oil recovery, and tertiary oil recovery. |
Polyacrylamide Flocculant for Water TreatmentThey include the purification of industrial water, sewage
treatment, drainage purification, and wastewater treatment.
Polyacrylamide is ideal for water treatment because of its ability
to increase viscosity and promote the flocculation of particles.
Flocculation is a process where suspended particles precipitate in
a fluid to form a clump or floc. It is an essential process in
water treatment.
PAM has good coagulation qualities that make it the best for water
purification. Coagulation is all about changing a liquid to a solid
or half-solid state by adding a specific chemical or coagulant.
Polyacrylamide products also combine with water to produce
insoluble hydroxides. This results in precipitation where the
insoluble hydroxides combine to form meshes that can trap tiny
particles into a more significant mass. Separating the larger
masses of solids from water is a simple process. The variance of
PAM to use will depend on the type of wastewater. Other determining
factors include chemicals, acids, and pollutants in the water.
To use PAM correctly for your purification needs, you have to
consider the type of wastewater you are dealing with. You will know
the solid particles and other impurities in the water you intend to
treat. This will help you go about the procedure as required with
the right PAM dosage. You can also pick one with all the qualities
needed for the kind of purification you plan to do. There is an
option of using PAM with polyaluminum chloride (PAC) for water
treatment. |
