Huesa&rsquo;s laboratory<br \/>\nbegan by carrying out a pilot test in which the direct treatment of the discharge with ultrafiltration<br \/>\nceramic membranes was tested. During this pilot test, the best applicable physical-chemical pre-treatment was previously analysed, concluding that the best alternative was a coagulation pre-treatment.<\/p>\n<p>Once a test was carried out with the complete treatment line selected (coagulation plus ceramic<br \/>\nultrafiltration), a rejection of around 10 % was obtained, which was characterised by high values of<br \/>\norganic contamination (always within the law).<\/p>\n<p>In any case, the rejection represented a very high operating cost in the solution proposed, so it was<br \/>\ndecided to pilot alternatives that would improve the quality of the treated water and significantly reduce the operating costs for rejection management.<\/p>\n<p>For this reason, a battery of tests was started in pilot plants using MBR, which combines biological<br \/>\ntreatment that increases the yields of organic pollution and surfactant elimination and reduces the<br \/>\noperating costs of reject management, with clarification using membranes, taking advantage of the good<br \/>\nresults detected in the previous pilot project described above.<\/p>\n<p>The aim of this new treatment is to determine the best technology from a technical and environmental<br \/>\npoint of view, comparing clarification with submerged membranes and external tubular membranes,<br \/>\nextending the piloting over a period such that the need for nutrients and sludge production in the<br \/>\nbiological reactor can be determined on a full-scale basis.<\/p>\n<p>Thus, both pilot plants are of MBR type, the biological part being identical for both. Clarification is carried out by means of membranes, so that the best possible clarification is guaranteed, using external tubular membranes in one plant and internal microfiltration membranes in the other plant.<\/p>\n<div id=\"attachment_17056\" style=\"width: 622px\" class=\"wp-caption aligncenter\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-17056\" class=\"wp-image-17056 size-full\" src=\"https:\/\/jhuesa.com\/wp-content\/uploads\/2023\/10\/MBR-membranas-sumergidas.jpg\" alt=\"membranas sumergidas\" width=\"612\" height=\"719\" srcset=\"https:\/\/jhuesa.com\/wp-content\/uploads\/2023\/10\/MBR-membranas-sumergidas.jpg 612w, https:\/\/jhuesa.com\/wp-content\/uploads\/2023\/10\/MBR-membranas-sumergidas-255x300.jpg 255w\" sizes=\"auto, (max-width: 612px) 100vw, 612px\" \/><p id=\"caption-attachment-17056\" class=\"wp-caption-text\">MBR reactor with submerged membranes<\/p><\/div>\n<p>&nbsp;<\/p>\n<div id=\"attachment_17060\" style=\"width: 602px\" class=\"wp-caption aligncenter\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-17060\" class=\"size-full wp-image-17060\" src=\"https:\/\/jhuesa.com\/wp-content\/uploads\/2023\/10\/MBR-membranas-externas.jpg\" alt=\"membranas externas\" width=\"592\" height=\"737\" srcset=\"https:\/\/jhuesa.com\/wp-content\/uploads\/2023\/10\/MBR-membranas-externas.jpg 592w, https:\/\/jhuesa.com\/wp-content\/uploads\/2023\/10\/MBR-membranas-externas-241x300.jpg 241w\" sizes=\"auto, (max-width: 592px) 100vw, 592px\" \/><p id=\"caption-attachment-17060\" class=\"wp-caption-text\">Skid pilot plant MBR external membrane<\/p><\/div>\n<p>The main conclusions of this pilot plant are detailed below:<\/p>\n<ul>\n<li>The quality of water treated with MBR is significantly improved compared to direct treatment<br \/>\nwith ultrafiltration membranes.<\/li>\n<li>The analytical quality is very similar for the two membrane alternatives tested in MBR treatment<br \/>\nin terms of COD, BOD5 and surfactants, the success of the treatment being due to the biological<br \/>\ntreatment.<\/li>\n<li>The most relevant difference between the two technologies was that the submerged membranes<br \/>\nrequired three cleanings due to the drastic loss of filtration capacity, while the external<br \/>\nmembranes did not require any cleaning during the whole pilot.<\/li>\n<\/ul>\n<h3><span class=\"ez-toc-section\" id=\"Adopted_solution\"><\/span>Adopted solution<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>In view of the pilots carried out, the technical department of J.
