Qu'est-ce qu'un d\u00e9canteur \u00e0 microsable ?<\/p>\n\n\n\n

  1. Un r\u00e9servoir de s\u00e9dimentation \u00e0 microsable est un dispositif innovant de traitement de l'eau qui permet une s\u00e9dimentation \u00e0 grande vitesse en ajoutant du microsable comme support de floculation. Sa charge surfacique peut \u00eatre jusqu'\u00e0 10 fois sup\u00e9rieure \u00e0 celle des proc\u00e9d\u00e9s traditionnels, et il est largement utilis\u00e9 dans la purification de l'eau potable, le traitement des eaux us\u00e9es industrielles et d'autres domaines.<\/li>\n\n\n\n

    Floculation \u00e0 l'aide d'un support de microsable : L'ajout de sable de quartz d'une taille de 0,1 \u00e0 0,3 mm comme noyau de floculation, combin\u00e9 \u00e0 des coagulants (tels que le PAC) et \u00e0 des floculants (tels que le PAM), permet de former des flocs de haute densit\u00e9.<\/p>\n\n\n\n

    Conception de la structure en trois \u00e9tapes : Elle comprend trois zones fonctionnelles : un bassin de coagulation (pour l'ajout de produits chimiques), un bassin de floculation (pour le m\u00e9lange de microsable) et un bassin de s\u00e9dimentation (pour la s\u00e9paration \u00e0 l'aide de tubes inclin\u00e9s).<\/p>\n\n\n\n

    Syst\u00e8me de contr\u00f4le intelligent : Utilise un syst\u00e8me de r\u00e9cup\u00e9ration de microsable contr\u00f4l\u00e9 par PLC, permettant d'atteindre un taux de recyclage des particules de sable de 98% par le biais d'un s\u00e9parateur \u00e0 hydrocyclone.<\/p>\n\n\n\n

      Approvisionnement en eau des municipalit\u00e9s : Particuli\u00e8rement adapt\u00e9 au traitement des sources d'eau \u00e0 basse temp\u00e9rature et \u00e0 faible turbidit\u00e9, avec une turbidit\u00e9 des effluents atteignant 1 \u00e0 2 NTU. Eaux us\u00e9es industrielles : Lors du traitement des eaux us\u00e9es de teinture\/\u00e9lectroplastie, le taux d'\u00e9limination des MES atteint plus de 95%, et le taux d'\u00e9limination des TP d\u00e9passe 80%. Gestion des eaux pluviales : La capacit\u00e9 de traitement atteint 120 m\u00b3\/(m\u00b2-h), utilis\u00e9e pour le traitement d'urgence de la pollution due aux d\u00e9bordements des eaux pluviales.<\/p>","protected":false},"excerpt":{"rendered":"

      What is a microsand sedimentation tank? Microsand Carrier Flocculation: By adding quartz sand with a particle size of 0.1-0.3mm as flocculation nuclei, combined with coagulants (such as PAC) and flocculants (such as PAM), high-density flocs are formed. Three-Stage Structure Design: Includes three functional areas: a coagulation tank (for adding chemicals), a flocculation tank (for mixing…<\/p>","protected":false},"author":1,"featured_media":1910,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_kad_post_transparent":"","_kad_post_title":"","_kad_post_layout":"","_kad_post_sidebar_id":"","_kad_post_content_style":"","_kad_post_vertical_padding":"","_kad_post_feature":"","_kad_post_feature_position":"","_kad_post_header":false,"_kad_post_footer":false,"_kad_post_classname":"","footnotes":""},"categories":[1,32],"tags":[704,703,702,706,705,219],"class_list":["post-2193","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-categorized","category-waste-water-treatment-news","tag-adding-quartz-sand","tag-microsand-carrier-flocculation","tag-microsand-sedimentation-tank","tag-municipal-water-supply","tag-plc-controlled","tag-sedimentation-tank"],"_links":{"self":[{"href":"https:\/\/www.luckywwtp.com\/fr\/wp-json\/wp\/v2\/posts\/2193","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.luckywwtp.com\/fr\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.luckywwtp.com\/fr\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.luckywwtp.com\/fr\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.luckywwtp.com\/fr\/wp-json\/wp\/v2\/comments?post=2193"}],"version-history":[{"count":1,"href":"https:\/\/www.luckywwtp.com\/fr\/wp-json\/wp\/v2\/posts\/2193\/revisions"}],"predecessor-version":[{"id":2194,"href":"https:\/\/www.luckywwtp.com\/fr\/wp-json\/wp\/v2\/posts\/2193\/revisions\/2194"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.luckywwtp.com\/fr\/wp-json\/wp\/v2\/media\/1910"}],"wp:attachment":[{"href":"https:\/\/www.luckywwtp.com\/fr\/wp-json\/wp\/v2\/media?parent=2193"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.luckywwtp.com\/fr\/wp-json\/wp\/v2\/categories?post=2193"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.luckywwtp.com\/fr\/wp-json\/wp\/v2\/tags?post=2193"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
