The activity will take place on Wednesday 19 of March, at 11: 30 hrs., In the Bright room of the Department of Mining Engineering.

Within the framework of the Seminar on Research in Geology, Mining, Metallurgy, and Environment (SIGMMA), organized by the Department of Mining Engineering of the University of La Serena, the exhibition '' Biological Reactors for the Treatment of Acid Drainage from Minas '', dictated by Dr. (c) Norma Pérez.

Dr. (c) Pérez, is a Biologist from the Universidad del Valle, Colombia (2006), Master of Science, mention of Microbiology at the Universidad de Concepción (2011) and candidate for a PhD in Agricultural Engineering, Water Resources, at the University of Concepción. He is also a member of the study groups on Bioremediation and Analysis of Contaminated Environments with Mining Liabilities.

In her presentation, Dr. (c) Pérez will describe her work related to the development of a biological treatment system where the reduction of sulphate with organic material predominates as reactive substrates, in particular the viability of biological treatment with active diffusion (TBDA) as new treatment system for water contaminated with metals. Results will be presented regarding the effect of the distribution of the reactive material, the operation under demanding conditions (low pH and high load of metals) and studies of the capacity of the inoculum to treat copper drainages. Emphasis will be placed on the chemical and microbiological results (molecular analysis of the microorganisms present in the remediation).

The activity will take place on Wednesday 19 of March, at the 11: 30 hrs., In the Bright room of the Department of Mining Engineering, Faculty of Engineering, University of La Serena, located on Benavente 980 street.
