Economic and environmental implications of the development of UASB reactors in Mexico for sustainable industrial wastewater treatment

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract The objective of this work is to demonstrate that the inclusion of an up‐flow anaerobic sludge bed (UASB reactor) within an industrial wastewater treatment plant reduces the plant's investment and operating costs compared to a system based solely on conventional complete‐mix activated sludge (CMAS), operating under the same design principles ...

Thermophilic anaerobic biodegradability of water from crude oil production in batch reactors

Revista Técnica de la Facultad de Ingeniería, 2010
The anaerobic biodegradability of water from crude oil production coming from the extraction of light petroleum (APPL), medium petroleum (APPM) and heavy petroleum (APPP) was studied under thermophilic conditions.

Thermochemical pre- and biological co-treatments to improve hydrolysis and methane production from poultry wastes [PDF]

, 2011
Poultry industry wastes, namely feathers and poultry litter, are an interesting source of substrate for biogas production. The aim of this work was to assess the biomethane potential of raw poultry wastes, as well as the possibility of enhancing this ...

A Study of High‐Emission Industries: How Policy, Strategy, and Technology Shape Corporate Social Responsibility Toward Carbon Neutrality

Corporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT The extant carbon neutrality (CN) literature largely offers macro‐ or meso‐level analyses, providing limited insights into implementation experiences that could inform granular policymaking and industry strategies. To address this gap, we examine the lived CN experiences of firms in the transportation, energy, manufacturing, and construction ...

ANAEROBIC-AEROBIC TREATMENT OF TEXTILE WASTEWATER IN A SEQUENCING BATCH REACTOR

Scientific Study & Research: Chemistry & Chemical Engineering, Biotechnology, Food Industry, 2014
In this work, the treatment of synthetic textile wastewater using sequential batch reactor (SBR) was studied. This in order to predict the effectiveness of biological treatment on wastewater containing dyes while minimizing the aeration cost.

Biological treatment of the organic fibre from the autoclaving of municipal solid wastes : preliminary results [PDF]

, 2012
Commingled municipal solid waste (MSW) was autoclaved in the presence of saturated steam for 30 min at 145 °C and 600 kPa. The organic fibre fraction from the autoclaved resulting material was examined for biodegradability.

Development and in vitro evaluation of chitosan nanoparticles encapsulating Phoenix dactylifera L. (Ajwah) seed extract with supporting in silico molecular docking analysis

Food Biomacromolecules, EarlyView.
Abstract This research describes the engineering of chitosan nanoparticles (CS NPs) via ionic gelation to encapsulate Ajwah seed extract (ASE), repurposing a plant waste product for its documented antioxidant and anticancer potential. Physicochemical analysis confirmed the formation of stable nanoparticles with hydrodynamic diameters between 152.3 and ...

Anaerobic degradation process of phthalic acid esters

浙江大学学报. 农业与生命科学版, 2006
Ten phthalic acid esters (PAEs) were tested anaerobically to assess their potential for biogas production. Results showed that biogas production decreased with the increasing alkyl chain length of PAEs resulting in its increased half-life.

Anaerobic biodegradation of hydrocarbons.

Science progress, 1990
The anaerobic biodegradation of hydrocarbons has long been a subject of controversy but enough data have now been accumulated to support the view that hydrocarbons can be metabolized in the natural environment in the absence of molecular oxygen. For a limited number of molecules, anaerobic hydrocarbon metabolism has been demonstrated under fermentative

Bioelectrochemical single reactor for reductive and oxidative removal of trichloroethylene from contaminated groundwater

Journal of Chemical Technology &Biotechnology, EarlyView.
Abstract BACKGROUND Chlorinated aliphatic hydrocarbons such as trichloroethylene (TCE) are persistent groundwater contaminants due to improper disposal and low biodegradability. This work presents an innovative bioelectrochemical system for the integrated reductive/oxidative removal of TCE from contaminated water, implemented in a single tubular ...
