Los resultados muestran que en términos de DQO los sistemas cumplen con la normativa aplicable para volcamiento en pozos absorbentes o absorción por suelo, siendo el sistema de tipo A el que mostro mayor concentración de DQO. Los niveles de coliformes fecales fueron altos en todos los sistemas evaluados, por lo que sería necesaria una etapa final de desinfección a los fines de minimizar los riesgos de contaminación de cuerpos de agua y afectaciones a la salud humana. Los sistemas descentralizados podrían ser una opción válida a ser tenida en cuenta formalmente en la planificación territorial y urbana en el área metropolitana del Valle de Lerma (AMVL). Sin embargo, es necesario profundizar la evaluación del funcionamiento de los sistemas, analizar las perspectivas sociales existentes y avanzar en la construcción de un marco legal que de formalidad y control a estas alternativas tecnológicas. ABSTRACT.-In this paper was evaluated twelve decentralized treatment systems of domestic wastewater located in different sectors of the metropolitan area of the Valle de Lerma, in the province of Salta (Argentina). Have been sampled three types of systems: (A) septic tank; (B) septic tank and UASB reactor; (C) Septic tank, UASB and slow filter. The results show that in terms of COD all systems comply with the regulations applicable to final disposal in wells or absorption by ground, with a system type A which showed higher concentration of COD. Fecal coliform levels were high in all systems evaluated, so a final disinfection stage coul be necessary in order to minimize the risks of contamination of water bodies and human health.

Los resultados muestran que en términos de DQO los sistemas cumplen con la normativa aplicable para volcamiento en pozos absorbentes o absorción por suelo, siendo el sistema de tipo A el que mostro mayor concentración de DQO. Los niveles de coliformes fecales fueron altos en todos los sistemas evaluados, por lo que sería necesaria una etapa final de desinfección a los fines de minimizar los riesgos de contaminación de cuerpos de agua y afectaciones a la salud humana. Los sistemas descentralizados podrían ser una opción válida a ser tenida en cuenta formalmente en la planificación territorial y urbana en el área metropolitana del Valle de Lerma (AMVL). Sin embargo, es necesario profundizar la evaluación del funcionamiento de los sistemas, analizar las perspectivas sociales existentes y avanzar en la construcción de un marco legal que de formalidad y control a estas alternativas tecnológicas. ABSTRACT.-In this paper was evaluated twelve decentralized treatment systems of domestic wastewater located in different sectors of the metropolitan area of the Valle de Lerma, in the province of Salta (Argentina). Have been sampled three types of systems: (A) septic tank; (B) septic tank and UASB reactor; (C) Septic tank, UASB and slow filter. The results show that in terms of COD all systems comply with the regulations applicable to final disposal in wells or absorption by ground, with a system type A which showed higher concentration of COD. Fecal coliform levels were high in all systems evaluated, so a final disinfection stage coul be necessary in order to minimize the risks of contamination of water bodies and human health. Decentralized systems could be a valid option to be formally taken into account in territorial and urban planning in the AMVL. However, it is necessary to deepen the performance evaluation of systems, assess existing social perspectives and progress in building a legal and formal framework to control the performance of these technological alternatives.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><a id="8cb83e414f42801a409a9d783aa84362" class="wp-workCard--action" rel="nofollow" data-click-track="profile-work-strip-download" data-download="{"attachment_id":57513035,"asset_id":37538671,"asset_type":"Work","button_location":"profile"}" href="https://www.academia.edu/attachments/57513035/download_file?s=profile"><span><i class="fa fa-arrow-down"></i></span><span>Download</span></a><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="37538671"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="37538671"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 37538671; window.Academia.workViewCountsFetcher.queue(workId, function (count) { var description = window.$h.commaizeInt(count) + " " + window.$h.pluralize(count, 'View'); $(".js-view-count[data-work-id=37538671]").text(description); $(".js-view-count[data-work-id=37538671]").attr('title', description).tooltip(); }); });</script></span></span><span><span class="percentile-widget hidden"><span class="u-mr2x work-percentile"></span></span><script>$(function () { var workId = 37538671; window.Academia.workPercentilesFetcher.queue(workId, function (percentileText) { var container = $(".js-work-strip[data-work-id='37538671']"); container.find('.work-percentile').text(percentileText.charAt(0).toUpperCase() + percentileText.slice(1)); container.find('.percentile-widget').show(); container.find('.percentile-widget').removeClass('hidden'); }); });</script></span></div><div id="work-strip-premium-row-container"></div></div></div><script> require.config({ waitSeconds: 90 })(["https://a.academia-assets.com/assets/wow_profile-a9bf3a2bc8c89fa2a77156577594264ee8a0f214d74241bc0fcd3f69f8d107ac.js","https://a.academia-assets.com/assets/work_edit-ad038b8c047c1a8d4fa01b402d530ff93c45fee2137a149a4a5398bc8ad67560.js"], function() { // from javascript_helper.rb var dispatcherData = {} if (true){ window.WowProfile.dispatcher = window.WowProfile.dispatcher || _.clone(Backbone.Events); dispatcherData = { dispatcher: window.WowProfile.dispatcher, downloadLinkId: "8cb83e414f42801a409a9d783aa84362" } } $('.js-work-strip[data-work-id=37538671]').each(function() { if (!$(this).data('initialized')) { new WowProfile.WorkStripView({ el: this, workJSON: {"id":37538671,"title":"TRATAMIENTO DESCENTRALIZADO DE AGUAS RESIDUALES DOMÉSTICAS EN EL ÁREA METROPOLITANA DEL VALLE DE LERMA, PROVINCIA DE SALTA, ARGENTINA.
