Evaluation system to alternative forced evaporation landfill leachate from the open air city Esteli

Abstract

 This research allowed to evaluate an alternative treatment system of leachate in the air of the city of Estelí by forced evaporation through a pilot dome greenhouse, where a system was established that simulates weather conditions, allowing an average evaporation of 0.78 cm / day and subsequently identifying gases and offensive odors emitted by leachate that were concentrated in the dome greenhouse after stabilizing these smells, which are almost negligible. This monitoring was performed for twenty consecutive days. During monitoring was determined the temperature for this leaching in a range of 26 ° up to 34 ° C with an average value of 31 ºC and this temperature range is typical for a process called anaerobic mesophile. The obtained values from measurement of evaporation showed an exponential tendency, meaning the higher the measuring point of the blade, the lower the evaporation. It deduces due to the work with two sheets of leachate within the dome. As it was analyzed during this investigation, the optimum was found at 20 cm. The implementation of this project, the evaluation of an alternative system of forced evaporation for leachate from the waste in the air of the city of Esteli, is a nationaly hardly studied field, and thus this is an opportunity and research technique that may eventually allow the use of economical and environmentally friendly technologies.
