Characterization and treatment of organic matter, UV quenching substances, and organic nitrogen in landfill leachates
… location, and on-site treatment processes. Size fractionation utilizing microfiltration (MF) and ultrafiltration (UF) was conducted in conjunction with TOC, nitrogen species, and UV254 absorbance analysis to determine the characteristics of organic constituents present in landfill leachate. The …

Impact of operating conditions on thermal hydrolysis pre-treated digestion return liquor
… in DON, which was primarily contributed by the hydrophilic fraction. An increase in temperature also resulted in increased UV254 absorbance. However, this trend was not linear and the increase was more pronounced when the temperature was increased from 150 C to 170 C. Increasing flash pressure …

Nanoemulsion-like Polymersomes for Nanoreactors
… approach, the amount of co-solvent and the hydrophilic fraction of amphiphilic block copolymer were varied and its effects on the size and dispersity were studied. Transport phenomena across the glassy and rubbery bilayer membranes was elucidated by NMR techniques to quantify the mobility …

Chemical characterisation of grapevine waste and bioactivity on cancer cell lines
… defatted seeds. The crude concentrated polar fractions and grape seed oil were subjected to both quantitative and qualitative chemical analysis. The total phenolic and flavonoid content, together with the condensed tannins and their relative degree of polymerisation were determined. The total …

Management strategy of landfill leachate and landfill gas condensate
… In a laboratory study, leachate samples were fractionated into humic acids (HA), fulvic acids (FA) and Hydrophilic (Hpi) fractions, the specific UV254 absorbance (SUVA254) of the three fractions follows: HA > FA > Hpi. However, the overall UV254 absorbance of the Hpi fraction was important …

Characterizing the effects of hydrothermal processes on bioactive compounds in wastewater bioenergy systems
… 7 days or less of treatment. HTL-WW was also fractionated into hydrophobic and hydrophilic fractions using XAD 8 resin. Algal bioassays with fractionated HTL-WW demonstrated that dissolved organic nitrogen (DON) in the hydrophilic fraction was effectively utilized for algal growth, whereas …
