preparation, performances, and mechanisms of microbial
in the application of flocculating agents, coagulants are always used to enhance flocculants’ performance. different kinds of microbial flocculants used different metal ions as coagulant aids (i.e., ca 2+, mg 2+, mn 2+, al 3+) . the presence of high concentrations of ca 2+ protects microbial
a review of nano-based materials used as flocculants for low cost,a study by akhlaghi et al. has shown that amine-functionalised cncs exhibited promising results as a flocculating agent in water treatment due to the presence of a high number of amine groups. at low ph, the zeta potential of the cncs was reported to change from negative to positive.
water soluble polymer flocculants synthesis
in addition to the rate of polymer adsorption and particle collisions, the rate at which the adsorbed polymer chains relax on the particle surface (eventually forming a flattened conformation) is crucial in determining the extent of flocculation, defined by gregory as equilibrium and nonequilibrium flocculation. 9 in the latter, the adsorbed polymer is still extended when particles collide

production, characterization, and flocculation mechanism of sale
introduction. flocculating agents, widely used in industrial processes such as wastewater treatment, are classified into three groups i.e., inorganic flocculants such as aluminium sulphate; organic synthetic high polymer flocculants such as polyacrylamide (pam); natural flocculants or bioflocculant such as microbial flocculant , .

natural and nano-conjugated polymers as bioflocculating
the flocculating activity was increased with the flocculating agent and its nanoform. the provided bioflocculating agents (chitosan and nano-chitosan) boosted up the flocculation by serving an additional substrate and polysaccharide source for microbial growth and multiplication (chutia et al. 2022; kala et al. 2023).

- What factors affect the flocculation effect of cationic polyacrylamide (CPAM)?
- 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.
- Can cationic polymer flocculants be developed by photo-polymerization?
- In this study, we utilized recent developments in the photo-polymerization technique to develop two cationic polymer flocculants by polymerizing two types of monomers for harvesting Chlorella vulgaris ( C. vulgaris) and Porphyridium purpureum ( P. purpureum ), which are freshwater and marine microalgae species, respectively.
- Which cationic polymer is used in direct flocculation?
- In direct flocculation, medium charge density with high molecular weight cationic polymers is normally used. It has dual functions: (1) neutralise the negative charges of the colloidal particles and (2) bridge the aggregated destabilised particles together to form flocs ( Chong, 2012 ).
- Which cationic polymer has the best flocculation efficiency?
- The PAmPTAC polymer had an optimal dose at 252 mg/g dry biomass. The difference in flocculation efficiency between two polymers is likely due to the differences in molecular weight. In the flocculation process by cationic polymers, charge neutralization of microalgal cells initiates floc formation.
