Polyacrylamide (IUPAC poly(2-propenamide) or poly(1-carbamoylethylene), abbreviated as PAM) is a polymer (-CH 2 CHCONH 2-) formed from acrylamide subunits. It can be synthesized as a simple linear-chain structure or cross-linked, typically using N,N '-methylenebisacrylamide.In the cross-linked form, the possibility of the monomer being present is reduced even further.
High molecular weight polyacrylamide nanoparticles
High molecular weight polyacrylamide (PAM) nanoparticle dispersions are products with wide application possibilities, the most important of which is in petroleum industry such as drilling fluid and flooding agent in enhanced oil recovery. For that aim, it is necessary to achieve complete control of the final dispersion and polymer properties during the synthesis step.

OS POLYCAP LQ – High Molecular Weight Liquid Polyacrylamide PHPA Partially-hydrolyzed polyacrylamide is a linear copolymer of anionic acrylate and nonionic acrylamide monomers. The polymer chain length and ratio of monomers can be varied during manufacture. PHPA acts as an excellent encapsulating polymer relying on a combination of anionic character and chain length to reduce…
Depressant function of high molecular weight
A high molecular weight polyacrylamide (PAM) was tested as a potential selective depressant in the differential flotation separation of galena and chalcopyrite using potassium ethyl xanthate (KEX) as a collector. In single mineral flotation, PAM depressed chalcopyrite while galena was floatable.
Cationic polyacrylamide is a derivative of polyacrylamide, a cationic polymer flocculant which has an excellent effect on sewage treatment. Our existing cationic polyacrylamide are mostly prepared by the Mannich reaction ,which has the shortcomings of more unreacted material, low cationic degree, poor stability, short validity, etc. Therefore, a cationic polyacrylamide has been prepared by

- What is dissolved air flotation?
- Dissolved air flotation is very widely used in treating the industrial wastewater effluents from oil refineries, petrochemical and chemical plants, natural gas processing plants, paper mills, general water treatment and similar industrial facilities. A very similar process known as induced gas flotation is also used for wastewater treatment.
- What is dissolved air flotation (DAF) technology?
- Dissolved air flotation (DAF) technology is one of the efficient techniques for purification of many types of wastewaters which contain pollutants less dense than water. Nowadays, due to high quality standards, wastewaters should be treated with high quality wastewater treatment techniques which meet the appropriate standards.
- What is flotation treatment?
- The flotation method was first used for ore dressing in the mining industry over a century ago. During flotation treatment, dispersed contaminants are fixed on the surface of air bubbles (flotation aggregate formation) resulting from physical and chemical interaction of three phases (water – air – particle).
- How to increase dissolved air flotation efficiency?
- Conclusion A theoretical analysis of principal guidelines to intensify the flotation wastewater treatment has evidenced the feasibility of increasing dissolved air flotation efficiency by reducing the depth of the flotation zone. A technique based on using lamellae elements facilitates a significant reduction in the depth of the flotation zone.
