flocculant chemicals polyacrylamide sciencedirect topics,flocculants with higher molecular weights are generally more effective. high molecular weight flocculants can adsorb several particles at once, forming a three-dimensional matrix. when this occurs, the aggregated cells become easier to harvest. this is why the most effective flocculants are polymers, either natural or synthetic [91,92].

biopolymer-based flocculants a review of recent technologies
hence, it is necessary to develop suitable biopolymer-based flocculants for removing cationic dyes and anionic dyes, respectively. for cationic dyes, sulfomethylated softwood kraft lignin could remove 99.1% of ethyl violet (cationic dye) from sewage, under the conditions of ph 9 and initial dye concentration of 300 mg/l (he et al. 2016). for
preparation, performances, and mechanisms of microbial,for a long time, inorganic flocculants and organic flocculants are mainly used in wastewater treatment both at home and abroad [].however, the sludge produced by treating the wastewater with aluminum salt flocculant is often used as a fertilizer in agriculture, resulting in high aluminum content in the soil, causing soil pollution and residue in plants.

- Which polyelectrolytes are used in water and wastewater treatment in South Africa?
- The two most commonly used polyelectrolytes for water and wastewater treatment in South Africa are polyamines and polydimethyldiallyl ammonium chloride (poly-DADMAC or poly–DMDAAC). Polyamines, also known as epichlorhydrin-dimethylamine (Epi-DMA) are cationic polymers formed by the polymerisation of epichlorhydrin and dimethylamine.
- How cationic polymers are synthesized?
- 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. The Mannich reaction is another important method by which the cationic polymers can be processed.
- 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.
- Can cation-active polyelectrolytes treat a water polluted with organic matter?
- This paper investigates the best attainable treatability to which a water polluted with a technologically significant concentration of organic matter is treatable by different cation-active polyelectrolytes and their blends with mineral coagulants in comparison to that attainable by traditional hydrolysing coagulants.
