Anaerobic degradation as an efficient system of removal of polymeric compounds. Biodegradability of polyethylene glycos of different molecular weight was assesed, due to the recalcitrant nature of these polymeric compounds, produced in many industrial wastewaters, hardly biodegradable. Anaerobic biodegradation of polyethylene glycol from 200...

En este trabajo se ha determinado la biodegradabilidad de polietilenglicol, de pesos moleculares medios comprendidos entre 200 y 35.000, en cultivos aerobios. Tradicionalmente estos compuestos polímericos se habían identificado como recalcitrantes y son componentes de aguas residuales industriales dificilmente biodegradables. Utilizando...

Degradation of polyethylene glycol by the integration of chemical and biological treattnent Biodegradation of polyethylene glycol 10.000 molecular weight or higher presented problems, therefore suggesting that integration of chemical and biological treatments, to achieve complete degradation from these sizes of polyethylene glycol may be...

This study evaluates the effect of anthropogenic activities on the quality of groundwater beneath a rural area (R'mel area) located in the perimeter of Loukkos, Northwest Morocco. Ten public wells for drinking water were sampled and characterized for physicochemical parameters, heavy metals and pesticides occurrence. Multivariate Statistical...

Recientemente está recibiendo gran aceptación el tratamiento integrado quimicobiológico de aguas residuales que contienen compuestos orgánicos defícilmente biodegradables. Sim embargo, estudios realizados con aguas sintéticas con ácido p-cumárico mostraron que el tratamiento químico previo al tratamiento biológico no mejoraba su degradación. En...

El presente trabajo se inscribe dentro del "Programa de Equipos Docentes para la Formación de Profesores Noveles" organizado por el Instituto de Ciencias de la Educación de la Universidad de Sevilla para el curso 03-04. El equipo docente que ha realizado la experiencia está compuesto por dos profesores noveles bajo la dirección de un profesor...

El diseño y la operación convencional del tratamiento secundario de aguas residuales urbanas presenta diferentes problemas como el bulking, foaming, la eliminación de nutrientes como nitrógeno y fósforo y el exceso de fangos. Para evitar estos problemas, se propuso, inicialmente, el uso de selectores con objeto de seleccionar las bacterias...

Mediterranean countries experience a large production of olive oil, thus generating huge quantities of non-biodegradable vegetation waters. The discharge of these effluents into aquatic environments seriously affects the quality of surface waters. This study investigated the potential use of carbon steel slag (SS) as an adsorbent and improver...

This paper describes an RP-HPLC method to characterize the ozonation products of polyethylene glycols (PEGs) (general formula HO(CH 2CH 2O) n -H) with original mass 5000. Samples with different pH and ozonation times were studied. The amounts of individual products up to n = 56, the percentage of PEGs as a final product and the molecular...

Landfill leachates contain a large number of recalcitrant compounds that make it unsuitable for conventional waste water treatment. This work has studied the effectiveness of a treatment method for the degradation of landfill leachates, based on a photocatalytic advanced oxidation process. The process consists of a photocatalytic treatment...

The relationship between agricultural activities, soil characteristics, and groundwater quality is critical, particularly in rural areas where groundwater directly supplies local people. In this paper, three agricultural sandy soils were sampled and analyzed for physicochemical parameters such as pH, water content, bulk density, electrical...

Municipal wastewater treatment plants typically exhibit two classic problems: high ammonium concentration in water after conventional biological treatment and, in some cases, poor activated sludge sediment ability. Potential solutions to these problems were investigated by adding a synthetic zeolite obtained from coal fly ash to different steps...

Carbonating metallurgical slags plays a pivotal role in achieving efficient mineral CO2 sequestration and waste valorization. This research introduces a novel integrated approach that combines the carbonation of Ladle Furnace Slag (LFS) with the simultaneous degradation of Methyl Orange (MO) in synthetic water. The comprehensive...

The treatment of municipal solid waste landfill leachate in a pilot plant made up of solar compound parabolic collectors, using a solid industrial titanium by-product (WTiO2) containing TiO2 and Fe(III) as a photocatalyst, was investigated. In the study evidence was found showing that the degradation performed with WTiO2 was mainly due to the...

El conocimiento del riesgo que implica la realización de prácticas de laboratorio es imprescindible para estudiantes de grados de Ingeniería, hombres y mujeres, como primer paso a la aplicación de medidas de prevención y protección en sus futuros trabajos profesionales y, en su caso, la detección de riesgos específicos asociados al género. Sin...

Este trabajo constituye una primera aproximación para la adaptación de la actual titulación de Ingeniería Técnica Industrial, especialidad en Química Industrial, al Espacio Europeo de Educación Superior (EEES). Considerando asignaturas propias de la especialidad, de diferente naturaleza (experimental ó teórico-práctica) y curso, se ha elaborado...
