Evaluation of the anaerobic degradation of black liquor from a Kraft pulp plant with addition of organic co-substrates
(I W A PUBLISHING, 2009)
The purpose of this study was to assess the anaerobic degradation of black liquor with and without additional carbon sources. Batch experiments were conducted using black liquor, from an integrated pulp and paper mill ...
Methanogenic potential and microbial community of anaerobic batch reactors at different ethylamine/sulfate ratios
(Brazilian Society of Chemical Engineering, 2011-03-01)
Methylamine and sulfate are compounds commonly found in wastewaters. This study aimed to determine the methanogenic potential of anaerobic reactors containing these compounds and to correlate it with their microbial ...
The recycling of biodigested vinasse in an upflow anaerobic sludge blanket reactor is a feasible approach for the conservation of freshwater in the biofuel ethanol industry
(2020-07-20)
The generation of large volumes of vinasse during the production of biofuel ethanol is a challenging problem since inappropriate application of the byproduct as an agro-fertigant can give rise to contamination of soil and ...
Water reuse: Dairy effluent treated by a hybrid anaerobic biofilm baffled reactor and its application in lettuce irrigation
(2021-08-01)
There is a synergy between the large quantities of organics-rich effluents generated by the dairy industry and the continually increasing water needs for crop irrigation. In this sense, this study aimed at evaluating the ...
Class and Home Problems: Modeling of an Industrial Anaerobic Digester: A Case Study for Undergraduate Students
(University of Florida, 2014-05)
The traditional approach in undergraduate chemical reaction engineering courses, as practiced in our uni-versity, is typically limited to design problems that can be solved by analytical methods. The study of single reaction ...
Disinfection of anaerobic/aerobic sanitary effluent using ozone: Formaldehyde formation
(2019-01-01)
The scarcity of natural resources supports the perspective of reusing treated effluents, mainly in agriculture, where the reduction in the demand of drinking water and the provision of alternative sources for nutrients are ...
Acidic and thermal pre-treatments for anaerobic digestion inoculum to improve hydrogen and volatile fatty acid production using xylose as the substrate
(2020-01-01)
Xylose is a by-product of lignocellulosic biomass processing for production of second-generation biofuels and could be suitable for bioproduct manufacturing. This paper describes an innovative approach that enables the ...
Influence of inoculum on performance of anaerobic reactors for treating municipal solid waste
(Elsevier B.V., 2004-09-01)
The influence of bovine rumen fluid inoculum during anaerobic treatment of the organic fraction of municipal solid waste (MSW) was studied in this work. The parameters adopted for evaluation were the biostabilization ...
Dynamics of sulfidogenesis associated to methanogenesis in horizontal-flow anaerobic immobilized biomass reactor
(ELSEVIER SCI LTD, 2009)
Two bench-scale horizontal anaerobic fixed bed reactors were tested to remove both sulfate and organic matter from wastewater. First, the reactors (R1 and R2) were supplied with synthetic wastewater containing sulfate and ...
