Microbial degradation of polyacrylamide and the deamination product polyacrylate - ScienceDirect
Polyacrylamide degradation, determined using the starch-cadmium method, was reported to be 45% under optimized conditions. Growth, measured as colony forming units was also demonstrated. In addition, analyses of the culture medium by SEC
A mean degradation rate of 9.8% per year was derived [92]. A very similar degradation rate was obtained for a polyacrylamide copolymer, which is not among the set of polymers considered in the
Understanding the impact of cationic polyacrylamide on anaerobic digestion of waste activated sludge - ScienceDirect
Cationic polyacrylamide (cPAM), a linear water-soluble polymeric compound with a high molecular weight and cationic charges, is widely used in enhancing solid-liquid separation through charge neutralization and interparticle bridging (Aguilar et
A novel amphoteric polyacrylamide (PDAA) was prepared by inverse emulsion polymerization. The influence of its cationic degree and molecular weight on retention property was discussed. Then, the chemical structure and micromorphology of the
Assessment of Polyacrylamide Degradation Using Advanced Oxidation Processes and Ferrate(VI) Oxidation
The degradation of these polymers using Fenton reagent, H2O2/UV, Fe2+/H2O2/UV, and Fe3+/H2O2/UV, as well as ferrate(VI), showed that PAM may present different behaviors under oxidation processes
Two methods involved the visual and spectrophotometric determination of the color change induced by a cationic dye, o-toluidine blue. The third method used a streaming current detector to monitor electrokinetic detection of charge

- Are poly-Aluminium chloride and aluminium sulphate effective coagulant agents?
- The efficiency of poly-aluminium chloride (PACl) and of aluminium sulphate (alum), two commonly applied coagulant agents, was studied comparatively in this work, during full-scale experiments in a drinking water treatment plant.
- Do high-poly-aluminum chloride sulfate coagulants remove humic acid?
- High-poly-aluminum chloride sulfate (HPACS) coagulants with different [SO42−]/ [Al3+] molar ratio (S) were prepared and proved to have high coagulation efficiency for the removal of humic acid and strong stability for storage and application. The results showed that the higher the SO42− addition, the bigger the alum
- What is aluminum chloride hydroxide?
- Aluminum chloride hydroxide, AlCl (OH) 2, AlCl 2 (OH), products, commonly known as polyaluminum chlorides (PAC), are used for a wide variety of industrial applications. Other names for PAC are basic aluminum chloride, polybasic aluminum chloride, aluminum hydroxychloride, aluminum oxychloride, and aluminum chlorohydrate.
- Does polyaluminum chloride coagulate with hydrolyzed coagulants?
- Coagulation with hydrolyzing coagulants has been studied thoroughly, but the coagulation behavior of pre-hydrolyzed coagulants such as polyaluminum chloride (PACl), especially the coagulation mechanisms at various coagulant dosages and pH values of raw water, has not been systemically investigated and not been well understood , .
