Polyelectrolyte flocculants in harvesting microalgal biomass

Tenney and co-workers reported an optimal dose of 2.5 mg L ? 1 for cationic polyelectrolyte flocculants used for harvesting chlorophytes [52]. Bilanovic and co-researchers demonstrated that cationic polyelectrolyte dosage required for flocculation range between 1 and 10 mg L ? 1 to flocculate freshwater strains [53]. It has already been

evaluation of anionic and cationic pulp-based flocculants

Evaluation of Anionic and Cationic Pulp-Based Flocculants

In wastewater treatment, flocculation is a widely used solid/liquid separation technique, which typically employs a charged polymer, a polyelectrolyte (PEL). Polyelectrolytes features, such as charge type, charge density and molecular weight, are essential parameters affecting the mechanism of flocculation and subsequent floc sedimentation.

A survey on cationic polyelectrolytes and their applications

Abstract 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.

Plant-based biopolymers: emerging bio-flocculants for

Research has shown that though all kinds of polyelectrolyte flocculants manage to attach to microalgal cell surfaces, the microalgal biomass flocculation, in particular, occurs only with the addition of cationic polymers (Danquah et al. 2009; Beltran-Heredia et al. 2009; Granados et al. 2012; Konig et al. 2014). The unfavorable outcomes

flocculation of clay suspensions by anionic and cationic

Flocculation of Clay Suspensions by Anionic and Cationic

In case of cationic polyelectrolyte, the optimum flocculant ratio (5¨C6 mg/g) corresponded to the ratio that gives the lowest electrophoretic mobility for each clay concentration and to the ratio that gives the fastest settling velocity for the highest clay concentrations (12¨C15 g/L), where static light scattering measurements were not possible.

Addressing water scarcity: cationic polyelectrolytes in water

Synthetic cationic polyelectrolytes (CPEs) serve as coagulation and flocculation agents in wastewater treatment due to a synergy of inherent electrostatic interactions and hydrophilic properties. In wastewater treatment, CPEs act as coagulation and flocculation agents to aggregate impurities and enable water purification.

Water Soluble Polymer Flocculants: Synthesis

There is no universally accepted formal definition for flocculation, but it is generally accepted that flocculation is the aggregation of solids achieved with the help of high molecular weight polymers through the formation of bridges between particles.

polymers for coagulation and flocculation in water treatment

Polymers for Coagulation and Flocculation in Water Treatment

The classification of the synthetic organic polymers used in water and wastewater treatment operations is based on the ionic charge present, e.g. cationic, anionic and non-ionic polyelectrolytes. Cationic polyelectrolytes formed the largest number of polymeric coagulants that have been used in CF operations.
