optimization conditions to obtain cationic polyacrylamide,flocculation is an essential industrial process for wastewater treatment . one of the most used flocculants for wastewater treatment and sludge de-watering is a water-soluble polymer produced by polymerizing acrylamide monomers or co-polymerizing acrylamide monomers with other monomers.
unveiling the mechanisms of how cationic polyacrylamide
cationic polyacrylamide, a flocculation powder widely used in wastewater pretreatment and sludge dewatering, was highly accumulated in waste activated sludge. however, its effect on short-chain fatty acids (scfas) accumulation from anaerobic fermentation of waste activated sludge has not been investigated.
pam chemical organic anionic cationic hydrolyzed polyacrylamide,pam and hpam biodegradation occur when microbes utilize the amide group of the polymer as a nitrogen source and/or the polymer carbon backbone as a carbon source. microbial biodegradation is favored since it yields higher removal efficiency without additional environmental pollution (liu et al., 2016; nyyssölä amp ahlgren, 2019 ).

as a flocculant, polyacrylamide is widely used in municipal wastewater, industrial wastewater treatment,and drinking water treatment from rivers and lakes. the adsorption and decolorization properties of polyacrylamide are commonly used in the papermaking, printing and dyeing, textile and leather production industries.
dry liquid polymers meeting industry standards,polymers in wastewater treatment. polymers separate solids from liquids through a process called flocculation. due to the name of the process, you will hear these specific water-soluble polymers referenced as flocculants or polymer flocculants. the polymers’ ability to flocculate solids is central to their role in water treatment.
- What spectroscopy is used to identify anionic polyacrylamide flocculant?
- The anionic polyacrylamide (APAM-T) flocculant was characterized by Fourier transform infrared spectroscopy (FTIR), 1 H nuclear magnetic resonance spectroscopy ( 1 H NMR), and scanning electron microscopy (SEM). Furthermore, the X-ray photoelectron spectroscopy (XPS) was conducted to measure the elemental composition.
- Is cationic Pam effective in flocculation?
- The success of anionic and cationic PAM in flocculation can be related to particle charges that allow for particle flocculation with polymers. Non-ionic PAM was shown to be ineffective at flocculating tailing particles. The ionicity of the polymer appears to be highly relevant here, based on the results.
- Does Apam-T microblock structure improve flocculation performance?
- In the floc particle size distribution and fragmentation and reflocculation experiments, the floc corresponding to APAM-T had the strongest regeneration ability after fragmentation, which further confirmed the criticality of the microblock structure in enhancing the flocculation performance.
- How is an anionic polyacrylamide flocculant synthesized?
- In this study, an anionic polyacrylamide flocculant was synthesized by ultrasonic initiated template copolymerization (USTP), using sodium allylsulfonate (SAS) and acrylamide (AM) as monomers, poly diallyl dimethyl ammonium chloride (polyDADMAC) as template, and 2,2′-azobis [2- (2-imidazolin-2-yl) propane] dihydrochloride (VA-044) as initiator.
