Book Description
El agua es fundamental para la vida, tanto humana como animal o vegetal, pero puede llegar a ser perjudicial si no se aplican los controles oportunos que garanticen su inocuidad. Su contaminación puede estar provocada por residuos agrícolas, industriales o domésticos. Así pues, una de las problemáticas del agua es la elevada concentración de compuestos orgánicos e inorgánicos como podrían ser el ácido húmico, los aniones y los cationes. Por este motivo, se debe de ejercer un control estricto sobre la calidad del agua; de manera que, se planteen diferentes tecnologías que aseguren una calidad acorde con las necesidades de la sociedad. En la actualidad, se han desarrollado nuevos materiales como la resina MIEX®, fabricada por Orica Watercare, que se basa en la tecnología de intercambio iónico. Este material, tiene la capacidad de disminuir considerablemente la materia en suspensión y las sustancias disueltas, mejorando el rendimiento de las etapas de tratamiento y por consiguiente, obteniéndose una mejoría global en el proceso de tratamiento convencional de potabilización de aguas. El presente estudio se desarrolla mediante dos etapas diferentes: una etapa inicial en batch y otra, utilizando una planta piloto a pequeña escala. En la etapa experimental de batch se analiza el efecto de la dosis de resina MIEX® en el equilibrio de adsorción y a partir de estos datos se evalúa que modelo de isoterma de adsorción puede describir mejor el comportamiento experimental. Por otra parte, en la etapa experimental correspondiente a la planta piloto, se observa el efecto que producen tres dosis diferentes de resina MIEX® en: los parámetros de la membrana (flujo de permeado, permeabilidad y presión transmembrana), la eliminación de la materia orgánica, la concentración de aniones (cloruro, bromuro, nitrato, yoduro y sulfato) así como la concentración de cationes (sodio, potasio, magnesio y calcio). Finalmente, se realiza un estudio del impacto ambiental y una evaluación económica del proyecto.

Book Description
Soil and Sediment Remediation discusses in detail a whole set of remediative technologies currently available to minimise their impact. Technologies for the treatment of soils and sediments in-situ (landfarming, bioscreens, bioventing, nutrient injection, phytoremediation) and ex-situ (landfarming, bio-heap treatment, soil suspension reactor) will be discussed. The microbiological, process technological and socio-economical aspects of these technologies will be addressed. Special attention will be given to novel biotechnological processes that utilise sulfur cycle conversions, e.g. sulfur and heavy metal removal from soils. Also the potential of phytoremediation will be highlighted. In addition, treatment schemes for the clean-up of polluted megasites, e.g. harbours and Manufactured Gaswork Plants (MGP), will be elaborated. The aim of Soil and Sediment Remediation is to introduce the reader in: the biogeochemical characteristics of soil and sediments- new techniques to study soil/sediment processes (molecular probes, microelectrodes, NMR) clean up technologies for soils polluted with organic (PAH, NAPL, solvents) or inorganic (heavy metals) pollutants- preventative and remediative strategies and technologies available in environmental engineering novel process applications and bioreactor designs for bioremediation the impact of soil pollution on society and its economic importance.

Book Description
This Handbook is the first to explore the extensive applications made with bioplastics & biocomposites for the packaging, automotive, biomedical, and construction industries. Bioplastics and biocomposites are becoming increasingly prominent because synthetic plastics and glass fiber composites are neither sustainable nor environmentally friendly. The Handbook of Bioplastics and Biocomposites Engineering Applications brings together scientists from academia and industry to report on current research and applications in the bioplastics and biocomposites arena. This new science is interdisciplinary and integrates pure and applied sciences such as chemistry, engineering and materials science. The Handbook focuses on five main categories of applications: Packaging; Civil Engineering; Biomedical; Automotive; General Engineering. The majority of the chapters review the properties, processing, characterization, synthesis and applications of the bio-based and biodegradable polymers and composites including: Polymers such as polylactic acid (PLA), polyhydroxybutyrate (PHB), guar gum based plastics, cellulose polyesters, starch based bioplastics, vegetable oil derived bioplastics, biopolyethylene, chitosan, etc. Thermoplastic and thermosetting bioplastics and biocomposites with a focus on the automobile industry. The ways how to improve the properties of bioplastics, polymer blends, and biocomposites by combining them with both synthetic and natural fillers and reinforcements such as nanoclays, nanotubes (CNTs), and natural fibers (both wood and plant fibers). Studies that expand the boundaries of bioplastics that will allow for the new materials to be applied to most generic engineering applications. The Handbook will be of central interest to engineers, scientists and researchers who are working in the fields of bioplastics, biocomposites, biomaterials for biomedical engineering, biochemistry, and materials science. The book will also be of great importance to engineers in many industries including automotive, biomedical, construction, and food packaging.
