La invención desarrollada en el ámbito químico presenta un procedimiento de limpieza de Fe y Mn en redes de distribución de aguas, enfocado a la limpieza del contenido de hierro (Fe) y manganeso (Mn) en la superficie interna de tuberías para consumo human

In developed countries the sanitation and treatment of urban wastewater is well sustained and technically solved by means of conventional pipe networksandsubsequentcentralizedtreatments.However,developingcountries lack these infrastructures and are in need of sustainable, decentralized and economically viable solutions for the disposal of their...

The determination of methanogenic and non-methanogenic activity requires careful analysis because don't exist a standardized method to find this bioindicator. Therefore, we wanted to evaluate and optimize this analytical method for the characterization of anaerobic sludge. We did five experiments, where we changed variables such as agitation,...

Environmental Technology is a 6 credits transversal subject included in the curriculum of all the degrees in Industrial Engineering at the Higher Polytechnic School of the University of Seville. In the last 5 academic courses, the students of this matter have been working with the concept of "Naturalization". In the different topics which are...

Olive mill wastewater (OMW) is a major watercourse pollutant agent with a high concentration of phenolic compounds. It is estimated that 30 million OMW m3 are released into rivers every year. Protecting the health of these courses against the uncontrolled discharges implies establishing an adequate legislation, where spillage control tools play...

The world olive oil production represents a very significant sector of the alimentary industry. Nonetheless, the spillages associated to the sector –olive mill wastewater (OMW)– imply serious environmental risks due to their difficult treatments. This study showcases the use of bioparticles from a soil that has repeatedly been contaminated by...

The Water Engineering Master Course is a university-specific degree at the University of Seville which nowadays can be coursed in two different modalities: "on line" and "semi-attendance". Its first edition took place at 2000 and since then, the average of graduated students has been of 40 students per course. The semi-attendance mode offers...

El sistema escalonado de tratamiento de aguas residuales pertenece al sector de la ingeniería del agua y es un sistema biológico aerobio de tratamiento de aguas residuales con aireación por gravedad y lecho rocoso como soporte de biomasa. Consta de varios cajones dispuestos escalonadamente y el agua se oxigena al pasar de un cajón al inferior...

The aim of this paper is to assess the feasibility of the co-digestion of olive mill industrial waste with urban sewage sludge from wastewater treatment plants (WWTP). These wastes include olive mill solid waste (OMSW) and olive mill effluent (OME). This co-digestion process enables the energetic exploitation of OMSW and/or OME and introduces...

El desarrollo de nueva y más estricta legislación en materia de tratamiento de residuos, hace necesaria la utilización y mejora de tecnologías no convencionales que eviten los problemas ambientales asociados a las técnicas de gestión tradicionales, tales como la deposición en vertedero. Los residuos agroindustriales presentan, en la mayoría de...

In this work, bacterial behavior on dense and porous titanium substrates is discussed. Porous titanium was fabricated by a space holder technique (using 50 vol%, NH4HCO3 with particle sizes between 250 and 355 μm). These substrates were coated by sulfonated PEEK (termed SPEEK). Characterization of the porous substrate was carried out using the...

Two main problems limit the success of titanium implants: bacterial infection, which restricts their osseointegration capacity; and the stiffness mismatch between the implant and the host cortical bone, which promotes bone resorption and risk of fracture. Porosity incorporation may reduce this difference in stiffness but compromise...
