Polyelectrolyte flocculants in freshwater and marine water

Polyelectrolyte flocculants provide cost-effective means to improve recovery of mineral ores and remove suspended material from wastewater. They are intentionally added to wastewater at levels between 10 and 100 mg/L and can be used for sludge conditioning at much higher levels (Cary et al. 1987).

Progress, challenges, and opportunities in enhancing NOM

In a review of the literature on flocculation and flocculants, Sharma et al. 20 reported that flocculation of NOM with polyelectrolytes may occur through a bridging mechanism. Such a polyelectrolyte bridging mechanism of flocculation was similarly presented by Bolto and Gregory. 11 Here segments of a polyelectrolyte chain adsorb on more than

Influence of polyelectrolytes and other polymer complexes on

Influence of charged functional groups of polyelectrolytes on flocculation efficiency was also confirmed by floc size analyses performed for kaolinite flocculation using cationic and anionic polyacrylamides. Large but loose flocs were obtained for anionic PAM in comparison to cationic PAM, accompanied by higher settling rates.

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.

organic polyelectrolytes in water treatment

Organic polyelectrolytes in water treatment

Introduction The main applications of organic polyelectrolytes in potable water production are in coagulation and flocculation, and in the dewatering of treatment plant sludges. The water production processes are usually followed by sedimentation and filtration, although with only slightly contaminated waters the sedimentation step may be omitted.

Frontiers | Evaluation of Anionic and Cationic Pulp-Based

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. The effectiveness of the process is also influenced

Hydraulic Retention Time Influence on Improving Flocculation

Hydraulic retention time (HRT) influence improving sludge flocculation with adding the polyelectrolytes (non-ionic, anionic, and cationic) was studied on an activated sludge (AS) system fed with synthetic domestic wastewater (SDW), dairy industry wastewater (DIW), and caramel industry wastewater (CIW). The sludge volumetric index, food/microorganism ratio (F/M), and mixed liquor volatile
