Les installations biologiques sont adapt\u00e9es \u00e0 l’\u00e9puration des rejets civils et\/ou industriels<\/strong>, si elles peuvent \u00eatre assimil\u00e9es \u00e0 des civils (c’est-\u00e0-dire li\u00e9es \u00e0 des activit\u00e9s de production qui sont essentiellement caract\u00e9ris\u00e9es par des charges organiques, plus ou moins continues).<\/p>\n\n

Les types de traitements biologiques<\/h2>\n\n

Les typologies d\u00e9puratives biologiques, pour le traitement des d\u00e9chets organiques, peuvent \u00eatre r\u00e9sum\u00e9s comme mentionn\u00e9 ci-dessous:<\/p>\n\n

  1. Installations \u00e0 boues activ\u00e9es<\/strong>, bas\u00e9s sur la d\u00e9puration qu\u2019est r\u00e9alis\u00e9 par une masse bact\u00e9rienne en suspension. Ils se sont longtemps impos\u00e9s pour leur grande souplesse de fonctionnement, les espaces relativement r\u00e9duits qui requi\u00e8rent et le co\u00fbt suffisamment contenu de l\u2019installation.<\/li>
  2. Syst\u00e8mes \u00e0 filtres percolateurs<\/strong>, bas\u00e9s sur la d\u00e9puration r\u00e9alis\u00e9e par une masse bact\u00e9rienne et des autres organismes qui se d\u00e9veloppent dans une base fixe. Ils sont caract\u00e9ris\u00e9s par simplicit\u00e9 de fonctionnement et les co\u00fbts r\u00e9duits d\u2019exploitation.<\/li>
  3. Syst\u00e8mes \u00e0 biodisques<\/strong>, sur la base du sch\u00e9ma fondamental typique des filtres \u00e0 percolation, ils utilisent, comme support de la masse bact\u00e9rienne, des disques en plastique sp\u00e9ciaux, mis en rotation, et partiellement immerg\u00e9s dans les eaux us\u00e9es \u00e0 traiter. Ils sont particuli\u00e8rement adapt\u00e9s aux petites et moyennes collectivit\u00e9s. Dans ces applications, ils repr\u00e9sentent une am\u00e9lioration par rapport aux filtres percolantes, tout en maintenant une faible consommation d\u2019\u00e9nergie.<\/li>
  4. Les syst\u00e8mes membranaires<\/strong>, d\u00e9rivent du couplage des proc\u00e9d\u00e9s traditionnels \u00e0 boues activ\u00e9es avec les proc\u00e9d\u00e9s de filtration sur membranes semi-perm\u00e9able. Les avantages majeurs li\u00e9s \u00e0 cette technologie r\u00e9sident dans la possibilit\u00e9 d\u2019\u00e9liminer ou de r\u00e9duire l\u2019unit\u00e9 de s\u00e9dimentation en aval du compartiment biologique, donc dans la possibilit\u00e9 de r\u00e9duire consid\u00e9rablement la taille des installations. La s\u00e9paration boue-eau, en effet, est assur\u00e9e par une membrane semi-perm\u00e9able et non plus conditionn\u00e9e par la capacit\u00e9 de d\u00e9cantation des boues activ\u00e9es.<\/li><\/ol>","protected":false},"excerpt":{"rendered":"
