Apa este principalul consumabil \u00een orice instala\u021bie de sp\u0103lare. O linie standard de PET de 2.000 kg\/h consum\u0103 4-5 tone de ap\u0103 pe or\u0103 dac\u0103 nu este recirculat\u0103. Implementarea unui sistem de ap\u0103 cu circuit \u00eenchis folosind Flota\u021bie cu aer dizolvat (DAF)<\/a> este o modalitate dovedit\u0103 de a reduce consumul, men\u021bin\u00e2nd \u00een acela\u0219i timp calitatea sp\u0103l\u0103rii necesar\u0103 pentru produsele de cur\u0103\u021bare chimice.<\/p>\n

La Rumtoo, integr\u0103m sisteme DAF pentru a viza cele trei valori principale ale apelor uzate industriale: solide \u00een suspensie (SS), gr\u0103simi, uleiuri \u0219i unsori (FOG) \u0219i cererea biochimic\u0103 de oxigen (BOD).<\/p>\n

Provocarea inginereasc\u0103: SS, FOG \u0219i BOD<\/h2>\n

Apele uzate provenite din reciclarea plasticului nu sunt doar \u201cmurdare\u201d; ele con\u021bin contaminan\u021bi specifici care contracareaz\u0103 filtrarea standard.
\n1. Solide \u00een suspensie (SS)<\/strong>Microplastice \u0219i fibre de h\u00e2rtie (<50 microni) care trec prin filtrele mecanice cu sit\u0103, dar transform\u0103 apa \u00een tulbure, reduc\u00e2nd eficacitatea sortatoarelor optice.
\n2. Gr\u0103simi, Uleiuri, Unsoare (FOG)<\/strong>Reziduuri din recipientele alimentare (recipiente din polipropilen\u0103, canistre de lapte din HDPE). Aceste elemente hidrofobe acoper\u0103 fulgii de plastic, \u00eempiedic\u00e2nd detergen\u021bii s\u0103 ac\u021bioneze.
\n3. CBO (Consumul Biologic de Oxigen)<\/strong>Substan\u021be organice dizolvate, cum ar fi zaharurile din sticlele de sucuri. CBO ridicat duce la cre\u0219terea bacteriilor \u0219i la mirosuri nepl\u0103cute \u00een rezervoarele de ap\u0103.<\/p>\n

Cum func\u021bioneaz\u0103 tehnologia DAF Rumtoo<\/h2>\n

Flota\u021bia cu aer dizolvat func\u021bioneaz\u0103 pe principiul densit\u0103\u021bii diferen\u021biale. Spre deosebire de rezervoarele de sedimentare care se bazeaz\u0103 pe gravita\u021bie (amprent\u0103 lent\u0103 \u0219i mare), DAF folose\u0219te microbule (30-50 microni) pentru a ridica contaminan\u021bii la suprafa\u021b\u0103.<\/p>\n

Procesul \u00een 4 etape<\/h3>\n
    \n
  1. Dozarea substan\u021belor chimice<\/strong>Tratarea apei cu un coagulant (de exemplu, PAC) \u0219i un floculant (PAM) pentru a lega particulele fine \u00een grupuri mai mari numite \u201cflocoane\u201d.<\/li>\n
  2. Injec\u021bie cu microbule<\/strong>Ap\u0103 saturat\u0103 cu aer la presiune ridicat\u0103 (5-7 bari) este eliberat\u0103 \u00een rezervor. Sc\u0103derea brusc\u0103 de presiune creeaz\u0103 milioane de microbule.<\/li>\n
  3. Aderen\u021b\u0103 \u0219i cre\u0219tere<\/strong>Bulele se ata\u0219eaz\u0103 de FOG \u0219i de floconii solizi, reduc\u00e2ndu-le densitatea sub ap\u0103. Acestea se ridic\u0103 rapid la suprafa\u021b\u0103.<\/li>\n
  4. Skimming<\/strong>Un racletor mecanic \u00eendep\u0103rteaz\u0103 p\u0103tura de n\u0103mol plutitoare, \u00een timp ce apa clarificat\u0103 este extras\u0103 de pe fund pentru reutilizare \u00een Linie de sp\u0103lat din plastic<\/a>.<\/li>\n<\/ol>\n

    Compara\u021bie de performan\u021b\u0103: DAF vs. Sedimentare<\/h2>\n

    Pentru instala\u021biile de reciclare, DAF este superior, deoarece particulele fine de plastic \u0219i uleiurile vor \u00een mod natural s\u0103 pluteasc\u0103, nu s\u0103 se scufunde.<\/p>\n\n\n\n\n\n\n\n\n

    Concluzie<\/h2>\n

    Instalarea unui Sistemul DAF<\/a> transform\u0103 apele uzate dintr-o datorie de eliminare \u00eentr-un activ reutilizabil. Cu programul chimic \u0219i dimensionarea potrivite, DAF poate elimina 90-95%+ de contaminan\u021bi \u021bint\u0103, ceea ce poate extinde semnificativ ciclurile de reutilizare a apei de sp\u0103lare \u0219i poate reduce costurile de dozare a substan\u021belor chimice \u0219i taxele de deversare \u00een mediu.<\/p>","protected":false},"excerpt":{"rendered":"
