Structural modification of regenerated Fuller Earth and its application in the adsorption of anionic and cationic dyes
Universidad Nacional de Colombia (Sede Medellín). Facultad de Minas., 2015Co-Authors: Beltran-pérez, Oscar Dario, Hormaza-anaguano Angelina, Zuluaga-diaz Benjamin, Cardona Gallo, Santiago AlonsoAbstract:Fuller's Earth is an inorganic material used in the electric industry for dielectric oil regeneration. After decontamination treatment, Fuller's Earth is regenerated and reused. In this study, the removal capacity of regenerated Fuller for the treatment of water contaminated with dyes of different nature and in turn, how this capacity can be increased by structural modification of the material was evaluated. Thus, the regenerated Fuller Earth without any modification reached 99% removal of methylene blue. However, for treatment of effluents contaminated with red 40, acid and thermal modification of material was required to obtain adsorption greater than 94% of the dye. In conclusion, regenerated Fuller Earth adsorbent is suitable for treating effluents contaminated with cationic coloring materials. However, removal of anionic dyes is not efficient, the structural modification of the material to be necessary to enhance the removal of these type colorants

Después de un tratamiento de descontaminación, la tierra Fuller se regenera y reutiliza. En este estudio se evaluó la capacidad de remoción de la tierra Fuller regenerada para el tratamiento de aguas contaminadas con colorantes de diferente naturaleza y a su vez, como esta capacidad puede ser aumentada mediante la modificación estructural del material. Así, la tierra Fuller regenerada sin ninguna modificación alcanzó remociones del 99% de azul de metileno. Sin embargo, para el tratamiento de efluentes contaminados con rojo 40 se requirió la modificación acida y térmica del material para obtener adsorciones superiores al 94% del colorante. En conclusión, la tierra Fuller regenerada es un material adsorbente adecuado para el tratamiento de efluentes contaminados con colorantes de naturaleza catiónica. No obstante, la remoción de colorantes aniónicos no es eficiente, siendo necesaria la modificación estructural del material para mejorar la remoción de este tipo de colorantes

Tecnologías de tratamiento para la tierra Fuller contaminada con aceite dieléctrico.
'Escuela de Ingenieria de Antioquia - EIA', 2013Co-Authors: Beltran-pérez, Oscar Dario, Berrío-giraldo L. I. Ivette), Agudelo E. A. Alexánder), Cardona Gallo, Santiago AlonsoAbstract:In recent years, Colombia has been implementing agreements and regulations for the proper handling and final disposal of hazardous waste, because the amount generated each time is increasing and the adverse impact that these residues in human health and environment. The Fuller Earth is an inorganic adsorbent material (mainly aluminosilicate mineral) used in the electrical industry for the regeneration of dielectric oil, a derivative of petroleum used as an electrical and thermal insulation in power transformers. After oil regeneration process, the content of polyaromatic hydrocarbons (or PAH�s by its initials in english) that has Fuller Earth it become a hazardous waste that requires proper treatment to reduce its pollution and allows its reuse or safely dispose in a landfill. This is why in this article reviews the available technologies for treating this type of hazardous waste (Fuller Earth contaminated with dielectric oil), dividing the treatments into two streams, physic-chemical technologies and biological, exploring alternatives appropriate and effective treatment. The limited information about existing treatments of Fuller Earth contaminated with dielectric oil have guided the review in terms of the technologies implemented in hydrocarbon contaminated soils being the analogy valid due to the similar physical characteristics presented by Fuller Earth with respect to a low soil carbon content.Desde faz em alguns anos em Colômbia vêm-se implementando convênios e normas para o adequado manejo e disposição final dos resíduos perigosos, como a quantidade gerada a cada vez vai em aumento e ao impacto adverso que estes resíduos apresentam no ser humano e o médio ambiente. A terra Fuller é um material inorgánico adsorbente (mineral de aluminosilicatos principalmente), utilizado na indústria eléctrica para a regeneração do azeite dieléctrico, um derivado do petróleo empregado como aislante eléctrico e térmico nos transformadores de potência. Após o processo de regeneração do azeite, o conteúdo de hidrocarburos do tipo poliaromáticos (ou os PAH por suas siglas em inglês) que apresenta a terra Fuller a convertem num resíduo perigoso que requer de um adequado tratamento, para que reduza sua contaminação e permita sua reutilização ou segura disposição final num recheado sanitário. Por isto, neste artigo se revisam as tecnologias disponíveis para o tratamento deste tipo de resíduo perigoso (terra Fuller contaminada com azeite dieléctrico), dividindo os tratamentos em duas correntes, as tecnologias fisicoquímicas e as biológicas, explorando as alternativas mais apropriadas e eficientes para seu tratamento. A escassa informação a respeito dos tratamentos existentes para a terra Fuller contaminada com azeite dieléctrico têm orientado a revisão em termos das tecnologias implementadas em solos contaminados com hidrocarburos sendo válida a analogia devido às similares características físicas que apresenta a terra Fuller com respeito a um solo de baixo conteúdo de carbono.Desde hace algunos años en Colombia se vienen implementando convenios y normas para el adecuado manejo y disposición final de los residuos peligrosos, debido a que la cantidad generada cada vez va en aumento y al impacto adverso que estos residuos presentan en el ser humano y el medio ambiente.
