evaluation an anionic polyacrylamide flocculant with low cost
anionic polyacrylamide (apam), synthesized with anionic monomer and acrylamide, is a macromolecular compound. it is applied to treat sewage with cationic charged particles because its anionic chemical groups have efficient charge neutralization ability and colloids destabilization ability [13], [14].
optimization conditions to obtain cationic polyacrylamide,depending on the market demands, a cpam product with a specific cationic degree may be required for a particular application. for example, biosolids dewatering flocculants typically require a cationic degree of 40–50%. to dewater very young, high f/m, pure bio-sludges, cpam with a cationic degree of 60–70% would be needed.
polymer based flocculants review of water purification
polyacrylamide (pam) is the basis for most commercial polymeric flocculants mentioned in the literature (anionic, cationic, or non-ionic); this polymer is also modifiable with combinations of comonomers.
degradation of polyacrylamide and its significance in nature,high quality flocculant polyacrylamide (pam) is commonly used as a flocculant in water and wastewater treatment, a soil conditioner, and a viscosity improver and friction enhancer.
water soluble polymer flocculants synthesis
1 introduction flocculants are long chain water soluble polymers used to separate non-settling fine solids (=particles) from aqueous suspensions. they are used in mineral processing, industrial and municipal wastewater treatment, oil sands tailings dewatering, paper making, and biotechnology. 1 4 this work reviews different kinds of water soluble flocculants, focusing on advances in

synthesis, properties and performance of organic polymers
the addition of a polymeric flocculant allows for the destabilization of suspended colloidal particles, and thus significantly increases their sedimentation rate. polymeric flocculants are generally divided into four categories, which include non-ionic, cationic, anionic, and amphoteric polymers.
the application of cationic polymer in water treatment.with the increasing demand for water resources, the recovery and reuse of municipal wastewater are very important. cationic flocculant is a non-toxic and effective cationic polymer in water treatment
optimizing the flocculation effect of cationic polyacrylamide
cationic polyacrylamide (cpam) is a commonly used flocculant for water treatment. factors that affect the flocculation effect and can be controlled manually include the type and dosage of cpam, wastewater ph, stirring time and settling time, and their reasonable setting is critical to the flocculation effect of cpam. in this paper, the optimal flocculation conditions of a novel cpam were

high purity polyacrylamide gel electrophoresis (sds‐page)
in polyacrylamide gel electrophoresis, proteins migrate in response to an electrical field through pores in a polyacrylamide gel matrix; pore size decreases with increasing acrylamide concentration. the combination of pore size and protein charge, size, and shape determines the migration rate of the protein.

- Who bought polyacrylamide flocculant?
- Commercial flocculant of polyacrylamide (PAM, MW of 2000–14,000 kDa) was bought from Aladdin Industrial Corporation (Shanghai, China). Anhydrous ethanol and acetone were supplied by Zhenqi Chemical Reagent Co., Ltd (Shanghai, China).
- What is a polymer flocculant?
- Among the synthetic polymer flocculants, the most important is water-soluble polyacrylamide (PAM)—a non-ionic, amorphous polymer which can be modified to ionic form in the copolymerization process [ 8, 9, 10 ]. The acrylamide monomer can be used for grafting or crosslinking of other type of polymers.
- Is acrylamide a cationic flocculant?
- The copolymer of acrylamide (AM) and DMC is used as an effective cationic flocculant in wastewater treatment. A series of copolymers of AM and DMC (PAMC) were synthesized using different approaches. In earlier studies, γ-ray irradiation with inverse emulsion polymerization was employed to copolymerize AM and DMC .
- How effective is PAMC flocculation in turbid water clarification?
- Chemical and morphology structures of PAMC were characterized and analyzed. Flocculation performance and kinetics were investigated in highly turbid water clarification. Most effective flocculation occurred at pH 4 with the flocculant which contained the highest cationic content.
