Waste activated sludge high‐rate treatment of septage: Biodegradability studies and contact phase trials towards a cleaner environment

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract The waste activated sludge high‐rate (WASHR) process, developed in our previous study, is used for septic wastewater treatment. This high‐rate contact stabilization pre‐treatment uses typical waste streams found in wastewater treatment plants to reduce a portion of the loadings on the main treatment trains.

Iron(III)‐loaded cation exchange resin: A dual approach for aqueous H2S removal and biogas desulphurization

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Left: Desulphurization method application. Right: Novel desulphurization method. Abstract The presence of hydrogen sulphide (H2S) in biogas poses significant environmental and operational challenges due to its corrosive and toxic properties. Thus, this study aimed to develop a dual‐function desulphurization system using a cation exchange resin (CIER ...

Volatile Profile of Cashew Apple Juice Fibers from Different Production Steps

open access: yesMolecules, 2015
This study aimed to determine the volatile profile of cashew apple fibers to verify which compounds are still present after successive washings and thus might be responsible for the undesirable remaining cashew-like aroma present in this co-product ...

Detection of Adulterated Oregano Samples Using Untargeted Headspace–Gas Chromatography–Ion Mobility Spectrometry Analysis

open access: yesFoods
Oregano is often adulterated for economic reasons. This fraud mainly consists of adding other species with lower commercial value, such as olive leaves.

Developing a Suitable Anion Exchange Layer Structure for Pure–Water Fed Bipolar Membrane CO2 Electrolysis

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A porous anion exchange layer (AEL) is implemented in a forward‐biased bipolar membrane CO2 electrolyzer to suppress carbonate crossover, support CO2 regeneration and maintain cathode alkalinity. Two fabrication strategies are compared—deposition on a silver gas diffusion electrode (GDE) or on the CEM—showing that a porous AEL‐coated GDE provides the ...

Establishment of a Purge and Trap Continuous-Flow Isotope Ratio Mass Spectrometer System for Analysis of Stable Nitrate Isotopes (δ<sup>15</sup>N and δ<sup>18</sup>O) in Water Samples by Ti(III) Reduction. [PDF]

open access: yesRapid Commun Mass Spectrom
ABSTRACT Rationale Pollution of surface and shallow groundwater by nitrate (NO3−$$ {\mathrm{NO}}_3^{-} $$) is a global concern, resulting in the deterioration of drinking water quality. Stable isotopes of NO3−$$ {\mathrm{NO}}_3^{-} $$ (δ15N and δ18O) can be used to trace its sources and identify prevailing biogeochemical processes.
