Article
Enzymatic processes offer an option for the treatment of rich-starch effluents from the industrial processing of potatoes, which has been usually provided by means coagulation-flocculation units followed by settling, filtering or mechanical separation stages. Pre-treatment of these effluents with amylase enzymes increases the biodegradable-soluble...
Article
Full-text available
The energy potential of high-organic loaded agro-industrial effluents receiving biological treatment is often neglected, particularly in emergent regions, because of different technical and regulatory drawbacks. In addition, small alternative bioenergy sources are forced to compete disadvantageously with conventional energy supply, hindering their...

Este documento analiza el estado del arte y las bases conceptuales sobre la transformación e innovación de la cultura organizacional en Instituciones de Educación Superior. Bajo la modalidad de preguntas orientadoras se dio respuesta a dos cuestionamientos principales: a) ¿Cuáles son los elementos diferenciadores de las organizaciones innovadoras,...
Article
Conventional biological processes used to treat high-polluted agro-industrial effluents produce biogas and sludge, two by-products stocking up important energy contents. Advanced biotechnologies to treat these effluents are being developed to obtain increased biogas production and other efficient and useful energy sources, such as bio-hydrogen and...
Article
Biogas produced in municipal and industrial wastewater treatment facilities (BWWF) is a resource wasted in several socioeconomic contexts. BWWF-based projects are compared against energy projects using conventional electricity or natural gas (NG), following strict economic considerations that usually tip the balance in favour of conventional energy...
Article
Mexico's government has introduced a Law on Climate Change that is unique worldwide; it establishes targets for greenhouse gases reductions at the same level of developed countries despite being an emerging country. This reform represents a crucial challenge for the electrical and transport sectors largely dependent on fossil energy since Mexico is...
Article

CWWTP are sanitation facilities formed by the coupling of an aerobic post-treatment (i.e. activated sludge, extended aeration, etc.) with a primary anaerobic treatment (i.e. UASB). In these combined arrangements, usually biogas produced in the UASB units is used to drive mechanical energy for aeration requirements in the secondary treatment (i.e. A...

Full-text available
Los digestores o reactores biológicos anaerobios de tipo UASB (Up-flow Anaerobic Sludge Blanquet), han demostrado ser una tecnología robusta y adaptable al tratamiento de aguas residuales de baja, media y alta carga, capaz de producir biogás con altas concentraciones de metano. Aunque los UASB son unidades simples en su configuración y operación, s...
Conference Paper
Full-text available
El modelamiento de digestores anaerobios busca una reproducción cada vez más realística de los diferentes procesos bioquímicos y fisicoquímicos que ocurren en estos equipos, haciéndose necesaria una determinación o estimación de variables y de parámetros biocinéticos. En la práctica, ésto conduce a una mejor capacidad de predecir, bajo diversas sit...

Greenhouse gas emissions from the waste sector account for only 4% of the total production, with wastewater management accounting for accurately 8 to 10% of this contribution. Wastewater disposal and treatment activities, mainly contributes to non-CO2 gases such as methane (CH4) and nitrous oxide (N2O). Capturing or avoiding these emissions is thus...
Article
The perovskite type oxide LaNiO3 was used as starting material for the CO2 reforming of methane. The reaction was studied by a pulse technique using a CH4/CO2 ratio close to one, in order to understand the catalyst behavior. LaNiO3 was reduced prior to the reaction by temperature programmed reduction (TPR) under hydrogen. The catalyst was thus comp...

Project
1. To identify and quantify hormones used as contraceptive, as well antibiotics surplus, in the input and output effluents of colombian WWTP to study their effectiveness to remove this kind of emergent pollutants 2. To adapt ELISA methods for low-cost and easier detection of hormones in water. 3. To study alternative pathways for technological adaptation of current colombian sanitation infrastructure to deal with recalcitrant hormones and antibiotics in the urban water cycle.
Project
