polyacrylamide used for municipal wasterwater treatment
Our products have demonstrated to be highly-effective in removing suspended particles and impurities from various types of wastewater.
Polyacrylamide is a linear polymer comprised of monomers unit with functional groups of amide that adsorb on to the surface of particles. These particles are bridged together by the long polymer chain drawing the particles closer together. This process is called flocculation and is widely used in wastewater treatment.
PAM has the ability to bridge together particles suspended in solution by an adsorption process. Polymers often have electrostatic charges that allow for surface particle neutralization resulting in flocculation.
ADSORPTION AND ADHESION
PAM creates reversible covalent bonds between particle surfaces allowing the particle to gain size and mass.
PAM can effectively reduce fluid friction in a pipe. The friction loss can be minimized by 50-80% with small amounts of PAM added to a liquid.
PAM is used to thicken a variety of sludges in both neutral and acidic conditions. PAM used for thicken can have additional structures such as branched and cross-linked. PAM will hydrolyze at pH values above 10.
Anionic PAM: It is widely used in waste water treatment of chemical industry, municipal sewage treatment, such as coal washing, mineral processing, metallurgy, iron and steel industry and electronic industry. It is also used in oil industry to enhance oil recovery which is widely used. In addition, it can be used as paper additives and textile pulp agent.
Cationic PAM: It is very efficient in usage and has high dehydration rate. It is used for the waste water treatment in alcohol factory, monosodium glutamate factory, sugar factory, beverage factory, tanneries, dyeing and other fields. It has a better effect to be used together with inorganic coagulant in particular. It can be used as paper additives as well.
Non-ionic PAM: It is the most appropriate to use NPAM, when the sewage is acidic. It is also used as agents for the textile pulp, paper chemicals, water shutoff agent, and etc.Because of its non-ionic functional group, PH value and salts have a little influence on NPAM’s flocculation. In the neutral or alkaline conditions, the flocculation effect is not as good as APAM, but better than APAM in acidic conditions.
