Preparation of a selective flocculant for treatment of oily

There are residual polymers in the oily wastewater produced from polymer flooding (OWPF); keeping the residual polymer in the water during the flocculation is meaningful and challenging. In this paper, a selective flocculant (denoted as PDC10) which can remove the oil while keeping partially hydrolyzed polyacrylamide (HPAM) in water was prepared by copolymerization of decyl two methyl

Flocculants: The First Step to Cleaner Water! - Lesson

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.

posite flocculant was 20 mg/L. The efficiency in the re-moval of COD and turbidity were enhanced with the in- creased dosage of composite flocculant. And the removal efficiencies of COD and turbidity reached the highest level when treated by sample 4 flocculant formula. How- ever, with the continuously increased dosage of composite

Recovery of iron from iron ore slimes by selective flocculation

The selective flocculation tests showed that the Fe grade can be enhanced from 58.24% to 64.60% Fe at a recovery of 66.33% using polyacrylamide as the flocculant. A Fe grade of 63.20% at a recovery of 68.04% was obtained using guar gum as flocculant.

US20030019815A1 - Process for preparing a flocculant for

The studies were performed suggesting that the cause of P2O5 losses during apatite-staffelite ores (ASO) treatment are due to non-selective flocculation of fine classes during flotation. When using strong flocculants, special preparation of condensed slurries is necessary, ensuring their deflocculation before the flotation process.
