Filtro subsuperficial para el co-tratamiento de lixiviados y aguas servidasel uso de biomedia plástica como material de filtro

Resumen

The most relevant elements in the design of subsurface horizontal filters are support material and flow control. Studying similar performance materials and improving them with new management procedures is essential to determine the economic and technical implications for sustainable application of these technologies in the future. To compare the performance of a new material with the one generally used in these systems, a pilot scale system was implemented, consisting of four treatment units in parallel. Two of the treatment units used gravel and two units used plastic material, with a higher specific surface area and porosity being ostensibly lighter. Two alternating units used a continuous flow system and two of them underwent a flow procedure that consisted of automatic, discontinuous filling and emptying, which allowed passive and alternate aeration of the support media.
