Descripción: “...No hubo diferencia estadística significativa p<0.05.Palabras clave: Cero recambio, Microorganismos eficientes, relación C:N,Tilapia.ABSTRACT:  The synergic, syntropic and metabiotic ability of a combination of lactic acid bacteria, phototrophic bacte- ria and yeast (also known as effective microorganisms – EM) to reduce residual water contamination is well recognised. Fish ponds’ organic matter (which would normally be eliminated) could be used as substrate for EM culture. ...”

Descripción: “...La escasa información acerca de los tratamientos existentes para la tierra Fuller contaminada con aceite dieléctrico han orientado la revisión en términos de las tecnologías implementadas en suelos contaminados con hidrocarburos siendo válida la analogía debido a las similares características físicas que presenta la tierra Fuller con respecto a un suelo de bajo contenido de carbono.Abstract: 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. ...”
