role of polyelectrolytes in the treatment of water flocculant
the most popular anionic polyelectrolyte contains weak carboxylic acid group, so its charge density depends upon ph (louren莽o et al. 2018). 10.3.2.3.1 anionic polyacrylamide (pam) high molecular weight carboxylic acid polymers derived from polyacrylamide are used as flocculant in water industries.
organic polyelectrolytes in water treatment,mw values range from a few thousand up to tens of millions. conventionally, polymers are regarded as having, low, medium or high mw, corresponding to mw values in the ranges: 10 5, 10 5 0 6 and 10 6, respectively. cd will be discussed later. all polymers used as flocculants in water treatment, must be water soluble.
application of polyelectrolytes for contaminant removal flocculant
pss is a typical, commercially available anionic polyelectrolyte with repeating sulfonate functional groups [30]. it can be used not only for wastewater treatment and water softening [[31], [32], [33]], but also for produced water treatment and pretreatment for seawater desalination [34, 35].

recent achievements in polymer bio-based flocculants for sale
the flocculants, designed for coal slime water treatment, were characterized using the ftir, xrd and sem methods. it has been shown that water turbidity was reduced by ~97% and ~94%, while cod removal was ~78 and ~74% in the presence of fe 3 o 4 -chitosan-cellulose and fe 3 o 4 -chitosan-biochar, respectively.
chemical polyacrylamide (PAM) flocculant types,polyacrylamide (pam) is a water-soluble linear polymer and one of the most widely used water-soluble polymer compounds.its derivatives find applications as efficient coagulants, thickeners, paper enhancers, and liquid friction reducers across various industries, including water treatment, papermaking, petroleum, coal, metallurgy, geology, textiles, and construction.
polymer based flocculants review of water purification
after treatment, the water content of the flocs generated by the hybrid flocculant was considerably lower than that of the compound and monomer flocculants, which can reduce flocculation time. the hybrid flocculant had fewer settling flocs, whereas the supernatant has more water after flocculation and a greater turbidity removal rate.
degradation of polyacrylamide and its derivatives in aqueous.general features of degradation of polyacrylamide and its anionic and cationic derivatives under the action of radical degradative agents are considered. the molecular weight of these polymers can be controlled by varying the structure and concentration of the degradative agent and salt additions, the concentration, molecular weight, and composition of the initial (co)polymer, and the process

- What are cationic polyelectrolytes?
- Cationic polyelectrolytes are water-soluble polymers bearing positive ionic groups along the backbone or in side chains. These cationic polymers are synthesized by free radical polymerization of acrylamide and their derivatives by the copolymerization method, which includes solution, precipitation, and emulsion techniques.
- What type of polyacrylamide is used in oil industry?
- The polyacrylamide use can be anionic, cationic, or nonionic with various ratios of the comonomers used in the case of the anionic and cationic polymers. The anionic polyacrylamides in the oil field industry are designated by the generic name of partially hydrolyzed polyacrylamide (PHPA), although they are in actuality copolymers .
- What are polyacrylamides polyacrylates?
- Polyacrylamides are available in all of the conceivable product forms and are used across a wide range of applications. The polyacrylates comprise another group of synthetic polyelectrolytes that are very diverse in their characteristics and utility.
- What are polymeric polyelectrolytes?
- There are many definitions for polymeric polyelectrolytes in the literature , , . In the simplest sense, water-soluble polyelectrolytes are polymers that contain charged disassociating monomer subunits. The charges can be pendant to the polymer chain or be part of the polymer chain itself.
