water soluble polymer flocculants synthesis
although researchers have tried to replace polyacrylamide with other flocculants due to the carcinogenic and toxic nature of acrylamide, no other alternatives have yet been synthesized with the same performance and cost advantages. 36. cationic flocculants are normally used to flocculate negatively charged particles, and are used in wastewater
polymer based flocculants review of water purification,examples of some of the findings in the literature on the subject of using polymer flocculants are: anionic flocculant is more effective at increasing the settling speed of slurries than cationic and non-ionic flocculants; when the ph, flocculant dosage, and shear rate rose, the relative flocculation rate increased at first and subsequently
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
recent achievements in polymer bio-based flocculants for sale,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. the acrylamide monomer can be used for grafting or crosslinking of other type of polymers.
high performance, cost-effective and ecofriendly flocculant
moreover, the cis flocculant showed excellent flocculation effects in ambient ph of 4–10, flocculation temperature of 10–40 °c, and various inorganic salts. in general, the anionic cis flocculant shows excellent cost effectiveness, where the predicted operation cost of as-prepared cis is about 60 % of conventional polyacrylamide flocculant.
the impact of anionic polyacrylamide (apam) on flocculant,with the purpose of improving the ultrafiltration (uf) efficiency, anionic polyacrylamide (apam) has been used as a coagulant aid in the flocculation-uf process. in this study, the impact of apam on uf efficiency has been investigated with regard to membrane fouling, membrane cleaning and effluent q …
research on a new cationic polyacrylamide (cpam) with high quality
flocculation is a common method to improve filtration efficiency and purify water quality in water supply plants where the commonly used flocculant is cationic polyacrylamide (cpam) (vandamme et al. 2010; teh et al. 2016). for sludge dewatering, cpam shows superior conditioning performance and obtained more and more attention.

synthesis and evaluation of cationic polyacrylamide flocculant
vu et al., [13] observed inorganic flocculant doses of up to 0.5 g/g of dry biomass was required for effective flocculation, resulting in high metal content in the harvested biomass. natural flocculants (e.g. chitosan, cationic polyacrylamide, and acacia tannin) have been used at doses of up to 0.3 g/g of dry biomass with culture ph adjustment [23].

synthesis of anionic polyacrylamide under uv,the results of xps and 1 h nmr spectroscopy analysis indicated the existence of anionic microblock structure in apam-t. besides, the copolymerization was revealed to follow the self-assembly mechanism by analyzing the association constant (k m). the flocculation performance was evaluated by turbidity and zeta potential in the flocculation tests.
- What is polyacrylamide used for?
- Polyacrylamide has effects of flocculation, thickening, drag reduction, adhesive, colloidal stabilizing, filming and preventing scale. It is widely used in papermaking, mining, coal washing, metallurgy, oil exploitation and other industrial sectors and is also a important chemical for water treatment. Figure 1 The synthetic route of polyacrylamide.
- What are the different types of polyacrylamide (PAM)?
- Explore the diverse applications of Polyacrylamide (PAM) types – Anionic, Cationic, and Non-ionic. Learn how these polymers are used in water treatment, wastewater treatment, and various industrial processes. Dive into the world of flocculants and polymer chemistry.
- What is the standard state of polyacrylamide?
- Unless otherwise stated, data refer to materials under standard conditions (25 °C [77 °F], 100 kPa). Polyacrylamide (abbreviated PAM or pAAM) is a polymer with the molecular formula (-CH 2 CHCONH 2 -).
- What is polyacrylamide polymer?
- Polyacrylamide, also briefly referred as PAM, is commonly a polymer with acrylamide monomers bonded connected by end to end configuration; it is a hard glassy solid at room temperature. Because of the difference in production methods, the products can be white powder, translucent beads and flaky like.
