recent achievements in polymer bio-based flocculants for low cost
five cationic water-soluble polymers with different molecular weights and charge densities were obtained and then applied as flocculant for kaolin suspension. it was found that the best flocculation properties showed polymer with highest charge density and molecular weight.
addressing water scarcity: cationic polyelectrolytes in water,in this review, we elaborate recent advances in cationic polyelectrolyte (cpe) synthetic methods used for several types of water treatment and characterization techniques of both cpes and aggregated impurities.
the use of cationic polymers as primary coagulants in water
the removal of natural organic matter (nom) from drinking water supplies can be achieved with cationic polymers, used here in jar tests on simulated waters made from concentrates of humic substances.

polyacrylamide degradation in oil field wastewater by uv/h2o2
model simulation has been widely used in rapidly and inexpensively predicting the rate constants of uv-aops. such work is primarily based on photochemical model and steady-state approximation models for reactive radical concentrations (ssa) [19],.
- What is polymer flooding?
- Polymer flooding is the most extensively used cEOR technique in field-scale projects, which may result in substantial oil recovery at a cheaper cost and for a broader range of reservoir conditions 247, 248.
- Why did tertiary polymer flood outperform secondary polymer flooding?
- In contrast, the cumulative oil recovery during the secondary polymer flood amounted to only 36% OOIP. In other words, the tertiary polymer flood outperformed the secondary polymer flood by recovering approximately 17% more oil. This enhanced performance of the tertiary polymer flood can be attributed to the vuggy nature of the dolomite.
- Which polymers are used for Polymer Flooding?
- Typically synthetic polymers are used by the oil industry for polymer flooding. Historically these were unhydrolyzed polyacrylamide-based polymers, selected because of their good chemical stability. However, it became apparent that these polymers did not increase viscosity substantially and showed a high level of adsorption onto mineral surfaces.
- How much oil was recovered during the tertiary polymer flood?
- Subsequently, the tertiary polymer flood contributed an additional 21% OOIP, resulting in a cumulative oil recovery of 53%. In contrast, the cumulative oil recovery during the secondary polymer flood amounted to only 36% OOIP.
