Anaerobic Treatment of Eucalyptus Fiberboard Manufacturing Wastewater by a Hybrid USBF Lab-Scale Reactor

Environmental Technology (1995)

José M. Fernández R. Méndez Juan M. Lema

A hybrid upflow sludge bed-filter anaerobic reactor (USBF) at lab-scale was used for the treatment of eucalyptus fiberboard manufacturing wastewater at 37ºC. A physical-chemical pre - treatment adding a neutral polyelectrolyte was applied to remove inert solids present in the wastewater that may accumulate in the reactor. Chemical Oxygen Demand (COD) removals around 94% were obtained at an organic loading rate (OLR) of 14.8 kg COD m−3 d−1, corresponding to a hydraulic retention time (HRT) of 3 days. About 70% of COD was converted to methane, giving a volumetric yield of 2.6 m3 CH4 m−3 reactor d−1 and about 7.8 m3 CH4 m−3 wastewater. The biogas methane content was approximately 53%.

Effects of Profile Depth and Management on the Composition of Labile and Total Soil Organic Matter

Soil Science Society of America Journal (2012)

M. Susan Erich Alain F. Plante José M. Fernández Ellen B. Mallory Tsutomu Ohno

Carbon in deeper soil layers may be more stable than that in surface soil due to differences in source, composition, and environmental conditions. We studied the effects of profile depth on soil organic matter (SOM) composition and stability by comparing soils which had received organic amendments since 1991 to non-amended soils from the same study. We used thermometric analysis and excitation-emission fluorescence spectroscopy to characterize total SOM as well as a highly labile fraction of soil organic carbon (SOC) extracted with water (about 1% of total SOC), a moderately labile fraction extracted by pyrophosphate (5–18% of total SOC), and the resistant fraction remaining in the soil after pyrophosphate extraction. The concentrations of both total and water-extractable C decreased with depth. Amended soils had more total SOC than non-amended soils at the 0- to 15- and 15- to 30-cm depths, but not at the 30- to 45-cm depth, and greater amounts of water-extractable C at all depths. The most thermally labile fraction of SOM in the bulk samples was not affected by either depth or amendment, while the thermally resistant fraction decreased slightly with depth, but was unaffected by amendment. The thermally refractory fraction was unaffected by amendment but increased with depth. Thermal analysis of the residue after sequential extraction confirmed that the sequential extraction procedure removed relatively labile C and left behind more stable organic matter. Both thermal analysis, of soil pre- and post-pyrophosphate extraction, and fluorescence of pyrophosphate-extractable C suggested that C deeper in the profile was more microbially decomposed than surface C.

Relationships between Biological and Thermal Indices of Soil Organic Matter Stability Differ with Soil Organic Carbon Level

Soil Science Society of America Journal (2013)

Clément Peltre José M. Fernández Joseph M. Craine Alain F. Plante

Thermal analysis techniques can provide an important addition to our understanding of soil organic matter (SOM) composition and stability. Several recent studies have linked thermal and biological stability of SOM; however, contrasting results have been reported. The objective of this study was to characterize the relationships between thermal and biological SOM stability for a wide range of mineral soils. Soils were collected from 28 sites from across the United States and analyzed by thermogravimetry (TG) and differential scanning calorimetry (DSC) coupled with CO2 evolved gas analysis (CO2–EGA). We compared thermal analysis results to mean soil respiration rates during incubation at 20°C for 365 d (R20). For soils with <30 g C kg−1 (low C), R20 was negatively correlated with the temperature at which half of the DSC energy is released and the temperature at which half of the CO2–EGA is evolved. Conversely, for soils with >30 g C kg−1 (high C), R20 was positively correlated with CO2–EGA and DSC energy released between 345 and 460°C and to SOM energy density (in J mg−1 C). Differences between low-C and high-C soils indicate the relative importance of mineral association of SOM in low-C soils and the abundance of intact plant debris that is relatively energy dense and thermally resistant but relatively easy to decompose in high-C soils. Above all, thermal analysis proved to be a useful technique for interpreting SOM stability, but sample C concentration must be considered because it affects the dominant SOM stabilization mechanisms and thermal analysis results.

Tratamiento de aguas residuales de las industrias de tablero de fibra

José M. Fernández

En este trabajo se realiza un estudio para la depuracion integral de las aguas residuales de la fabricacion de tablero de fibra (ARFTF). El estudio se divide en dos fases, la primera, realizada a escala de laboratorio, y la segunda, consistente en el diseno y desarrollo del proceso a nivel piloto industrial. En la etapa de laboratorio se evalua: I) pretratamiento fisicoquimico del efluente bruto mediante la adicion de diversos coagulantes y floculantes; II) tratamiento anaerobio por medio de tres tecnologias diferentes (UASB, filtro anaerobio y reactor hibrido USBF); Y III) postratamiento (biologico aerobio y fisicoquimico). En la operacion a nivel piloto industrial se evalua la eficacia de tratamiento por medio de un reactor de tecnologia hibrida UASB-FA (USBF), al ser el equipo con el cual se obtuvieron los mejores resultados a escala de laboratorio, utilizando como pretratamiento un proceso de floculacion-decantacion. En ambas etapas se estudian aspectos como, capacidades, eficacias y estabilidad del proceso de tratamiento, asi como estudios de eliminacion de compuestos especificos como azucares totales y reductores, compuestos fenolicos y compuestos causantes de toxicidad biouminiscente evaluada por photobacterium phosphoreum, a la alimentacion y efluente de los correspondientes reactores. En base a estos estudios se propone un prediseno de la planta industrial consistente en un sistema que combina un proceso de pretratamiento fisicoquimico, tratamiento biologico anaerobio y un postratamiento biologico aerobio.

Caracterización de las aguas residuales de la planta refinadora de aceites comestibles ERASOL

Revista CENIC. Ciencias Biológicas (2007)

A. Ábalos A. Marañón José M. Fernández Isabel Aguilera María Fernanda Despaigne

The pollution of the smattering waters and receiver bodies, is a dan- gerous environmental problem actually. The Santiago de Cuba bay, the second most important economic in the country, receives daily the environmental impact of the 27 pollute focus; being the food industry a sector socioeconomic with high incidence in the pollution of its waters because of the discharge of a lot of quantity of waste- waters without treatment from different process of this industry. The production of the soybean oil (Glycine max) in the refiner plant of eatable oils ERASOL produce approximately 72 m 3 / d of waste that are poured directly in the bay without any previ- ous treatment. The aim of this work is the characterization of the wastewaters of the refinated soybean oil having in mind the environmental parameters and the rules of the Cuban pattern for the drain in receptor marine bodies. The analysis showed that the bay receives a lot of wastewater from ERASOL with 9,7 pH, 40232,50 mg/L of organic loads, 18537,13 mg/L of oils and 0,2 mL/L of sedimentable solids. These results showed that wastewaters of the ERASOL plant don't fulfil with the specifications of the Cuban standard in marine bodies. INTRODUCCION
