Targeting nanoplastic and microplastic removal in treated wastewater with a simple indicator - Nature Water

The use of cPAM flocculant is therefore probably introducing additional removal pathways for nanoplastics through charge neutralization that result in deviations from the orthokinetic model. For

Comprehensive assessment of flocculation conditioning of dredged sediment using organic polymers: Dredged sediment dewaterability and release

Flocculants can inhibit the release of ON in sediment, and the inhibition effect was inversely proportional to organic polymer MW. CS flocculation increased NH 3-N in the separated water from 0.08 mg?L ?1 to 0.35 mg?L ?1 (CS-3), 0.36 mg?L ?1 (CS-5), and 0.31

Research on a new cationic polyacrylamide (CPAM) with a cationic microblock structure and its enhanced effect on sludge condition and

Flocculation is one of the commonly used sludge conditioning methods in water supply plants, which can improve the sludge dewatering performance by reducing the specific resistance of sludge (SRF), decreasing the amount of sludge, and finally lowering the transportation cost and subsequent disposal cost of sludge.

Tools Share Abstract 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.

effect of cationic polyacrylamide on precipitated calcium carbonate flocculation: kinetics, charge density and ionic strength

Effect of cationic polyacrylamide on precipitated calcium carbonate flocculation: Kinetics, charge density and ionic strength

In the absence of salt, lags of PCC flocculation were observed at the lower polymer dosage (2 mg of CPAM/g of PCC) (Fig. 1 B), where the CPAM of lower charge densities had a longer induction period. However, this induction time was shortened and became similar for all CPAMs of different charge densities under slightly increased ionic strength (0.01) ( Fig. 1 D).

Effect of cationic polyacrylamide on precipitated calcium carbonate flocculation: Kinetics, charge density and ionic strength

Highlights Ionic strength and polymer charge% affect CPAM adsorption kinetics and PCC flocculation. CPAM adsorption kinetics is more important than adsorbed amount for PCC flocculation. Maximum rate in PCC flocculation is not at half monolayer surface coverage by CPAM. CPAM adsorbed on PCC increase with CPAM charge%; trend reversed at high ionic strength. CPAM adsorbs on PCC by electrostatic
