Croatia Non-Ionic Temperature-Resistant And Salt-Resistant Polyacrylamide for Paper Industry Wastewater Treatment

Nov 01, 2021 · On the contrary, Plasmodium putida laccase MTCC7525 decolourised synthetic dyes and paper mill effluent by 74–93% and 58–68% at 4–5 and 2–3 days treatment period (Kuddus et al., 2013). Additionally, Navas et al. (2020) reported Thermus sp. 29 laccases to potentially decolourised xylidine, RBBR, Gentian Violet, and methyl orange by 98% ...

Jan 24, 2018 · Such considerations have led to the recommendation of °C as a safe temperature range for the use of polyacrylamide in seawater and brine during polymer flooding [15][16][17][18][19][20][21].

The most used solvent in supercritical fluid extraction is carbon dioxide (CO 2), due to its non-toxicity, availability, and low critical temperature and pressure, among other advantages [39,45]. However, CO 2 is a non-polar molecule while tannins are considered polar compounds.

Mixed gel electrolytes were fabricated chemically at a temperature range of 2–5°C using some additives comparing with traditional electrolytes (1.26 g/cm 3 H 2 SO 4 ). The polyacrylamide (PAM) content is kept constant (0.2 wt%), while the propylene glycol (PPG) and nano fumed silica (NFS) contents varied.

Non-ionic polyacrylamide_OKCHEM. Non-ionic polyacrylamide, a type of high polymer with high molecular weight and low ion degree, has such functions as flocculation, dispersion, thickening, cementation, film formation, gel formation, and colloid stabilization. Its flocculation effect is little affected by PH value and salt. During treatment of ...

Jan 25, 2021 · 2. Energy Conversion. The world is facing the exponentially increasing energy demands. Apart from the unprecedented decline in global energy demand (3.8%) in 2020 owing to the impacts of the Covid-19 crises and lockdowns, world total energy demands are forecasted to increase by 1.3% each year according to the international energy agency’s annual projections …
