high molecular weight flocculants are capable of promoting flocculation by neutralizing the superficial electric charges of sludge particles in the water and destabilising each individual particle. the particles then are absorbed by the activated functional group in the flocculant polymer. product characteristics superior floc formation

- 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.
- Can microbial flocculant be used in papermaking wastewater treatment?
- If such wastewater cannot be effectively solved, it will easily cause harm to the aquatic environment [ 96, 97 ]. In the study of papermaking wastewater treatment with the extraction of microbial flocculant, the flocculation effect is good and the removal rate of ammonia nitrogen can be as high as 96% under the optimum flocculation conditions.
- 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.
