optimising the activity of acrylamide-based polymer solutions

he noted the quality of process water available for make-up often reflected operational issues treating the tailings, e.g. the inability at one site to consistently dispense dry lime led to fluctuations in ph and ca 2+ concentrations. upgrading make-up water sources when high dissolved solids were present substantially reduced flocculant

aerobic degradation of anionic polyacrylamide in oil sands,treatment of the oil sands tailings using pure anionic polyacrylamide showed relatively high initial settling rate (isr) of ~ 10.3 m/h but with poor supernatant clarity ( 1000 ntu); while the

enhanced flocculation of oil sands mature fine tailings using

though some research groups have tested acrylamide copolymers as flocculants for oil sands tailings, to the best of our knowledge, there are only few studies that have performed a systematic study of the causes for improved dewatering and consolidation of oil sands tailings in the open literature. 5, 6, 13-15 for example, reis et al. varied the

a two-step flocculation process on oil sands tailings,treatment of the oil sands tailings using pure anionic polyacrylamide showed relatively high initial settling rate (isr) of ~ 10.3 m/h but with poor supernatant clarity ( 1000 ntu); while the treatment using pure cationic polymer resulted in clear supernatant (turbidity as low as 22 ntu) but relatively low isr of 2 m/h.

experimental study on the mechanical properties of polymer

furthermore, the shear strength of polyacrylamide-treated tailings clay and tailings silt increases by 5.46 ~ 13.02% and 8.41 ~ 34.12%, respectively. for the polyacrylamide-treated tailings sand, the shear strength increases by 6.88% compared with that of untreated tailings sand when the confining pressure is 100 kpa.

aerobic degradation of anionic polyacrylamide in oil sands

the compositions of tailings and process water are listed in table 1. a hydrolyzed polyacrylamide (snf, canada) with a medium anionic charge density and a high molecular weight of around 2.12 ×10 6 g/mol, was employed as a polymer flocculant. acrylamide ( 99.9 % pure; powder) was purchased from sigma aldrich, while pure sand (silica, 40–100 mesh),

mechanical properties of dna-crosslinked polyacrylamide,dna-cross-linked polyacrylamide hydrogels (dna gels) are dynamic mechanical substrates. the addition of dna oligomers can either increase or decrease the crosslinker density to modulate mechanical properties. these dna-responsive gels show promise as substrates for cell culture and tissue-engineerin …
