- Activated charcoal production from tree pruning in the Amazon region of Brazil for the treatment of gray water Marcelo M. Pedroza Leonardo H. D. Neves Elaine C. S. Paz Fabrício M. Silva Claudia S. A. Rezende Aymara G. N. Colen Matheus G. Arruda Ingeniería coal Pyrolysis gray water tree pruning filtration column The objective of this work was to obtain, through the tree pruning pyrolysis, coal to be used in the removal of pollutants present in gray waters. The coal obtained during the process was used in a gray water filtration column and dye adsorption test. In this investigation it was proposed the treatment of gray water by the following series steps: (a) coagulation/ flocculation, (b) decantation, (c) sand filtration and (d) coal filtration column. The maximum coal yield was 60.10% obtained at 360 ºC and heating rate of 30 ºC/min. The gray water polishing using the coal obtained from the tree pruning pyrolysis process was efficient in the removal of the studied analytical parameters. For turbidity, COD, total solids and residual chlorine parameters, the removal values were 99, 98, 71 and 100 %, respectively. The charcoal from the filtration column was responsible for removing organ matter of gray water. 2021 artículo científico 1665-6423 https://www.redalyc.org/articulo.oa?id=47471683006 https://www.redalyc.org/journal/474/47471683006/ https://www.redalyc.org/journal/474/47471683006/html/ https://www.redalyc.org/journal/474/47471683006/47471683006.epub https://www.redalyc.org/journal/474/47471683006/movil 10.14482/INDES.30.1.303.661 en http://www.redalyc.org/revista.oa?id=474 Journal of Applied Research and Technology application/pdf Universidad Nacional Autónoma de México Journal of Applied Research and Technology (México) Num.1 Vol.19
