Pentru ce sunt separatoarele de gr\u0103sime?<\/h3>\n\n\n\n

  Separatoarele de gr\u0103sime (uneori se mai numesc \u0219i capcane pentru gr\u0103simi, capcane pentru gr\u0103simi, capcane pentru gr\u0103simi sunt destinate cur\u0103\u021b\u0103rii apelor menajere \u0219i industriale similare compozi\u021biei lor cu un con\u021binut ridicat de gr\u0103simi.<\/p>\n\n\n\n

Evacuarea apelor uzate de acest tip duce la colmatarea sistemelor de canalizare \u0219i, de asemenea, \u00eempiedic\u0103 fluxul proceselor naturale de cur\u0103\u021bare biologic\u0103, afecteaz\u0103 negativ buna func\u021bionare a sistemelor de canalizare autonome. Legisla\u021bia impune cerin\u021be ridicate entit\u0103\u021bilor comerciale \u00een domeniul protec\u021biei apelor subterane. Produsele de descompunere a gr\u0103similor reprezint\u0103 o amenin\u021bare grav\u0103 pentru mediu. Este obligatorie utilizarea separatoarelor de gr\u0103sime de c\u0103tre restaurante, cafenele, puncte alimentare de la \u00eentreprinderi, cofet\u0103rii etc.<\/p>\n\n\n\n

Cum func\u021bioneaz\u0103 un separator de gr\u0103sime?<\/h3>\n\n\n\n

Separatoarele de gr\u0103sime sunt curg\u0103toare, ceea ce \u00eenseamn\u0103 c\u0103 sunt separate mecanic de gr\u0103simi \u00een timpul fluxului de ap\u0103 uzat\u0103 prin separator. Datorit\u0103 specificit\u0103\u021bii mecanismului de ac\u021biune, separatorul de gr\u0103sime este, de asemenea, capabil s\u0103 re\u021bin\u0103 par\u021bial suspensia care se \u00eencadreaz\u0103 u\u0219or, care este colectat\u0103 \u00een camera de colectare a sedimentelor din partea inferioar\u0103 a capcanei de gr\u0103sime.<\/p>\n\n\n\n

Cu condi\u021bia ca capacitatea nominal\u0103 s\u0103 fie corect selectat\u0103 \u0219i s\u0103 treac\u0103 debitul nominal, volumul de lucru al separatorului este suficient pentru ca pic\u0103turi mari de gr\u0103sime s\u0103 se ridice la suprafa\u021b\u0103 \u0219i s\u0103 se combine \u00eentr-un strat uniform.<\/p>\n\n\n\n

Cum se alege un separator de gr\u0103sime?<\/h3>\n\n\n\n

La alegerea unui separator de gr\u0103simi, se ia \u00een considerare natura \u0219i cantitatea de ap\u0103 uzat\u0103 pentru care este destinat\u0103, precum \u0219i:<\/p>\n\n\n\n

- debitul maxim a\u0219teptat;<\/p>\n\n\n\n

- temperatura maxim\u0103 a apelor uzate;<\/p>\n\n\n\n

- densitatea gr\u0103similor separate (uleiuri);<\/p>\n\n\n\n

- influen\u021ba altor factori asupra procesului de cur\u0103\u021bare.<\/p>\n\n\n\n

Dac\u0103 nu exist\u0103 cerin\u021be speciale de reglementare care reglementeaz\u0103 dimensiunea separatorului pentru o anumit\u0103 instala\u021bie, valoarea sa nominal\u0103 poate fi calculat\u0103 utiliz\u00e2nd urm\u0103toarea formul\u0103:<\/p>\n\n\n\n

NS = Qs x ft x fd x fr<\/p>\n\n\n\n

NS - dimensiunea nominal\u0103 a separatorului<\/p>\n\n\n\n

Qs este debitul maxim \u00een l \/ s.<\/p>\n\n\n\n

ft - coeficientul temperaturii apei uzate<\/p>\n\n\n\n

fd - coeficientul de densitate al apelor uzate<\/p>\n\n\n\n

fr - coeficientul con\u021binutului de detergent din efluen\u021bi<\/p>\n\n\n\n

Cum se men\u021bine un separator de gr\u0103sime?<\/h3>\n\n\n\n

Separatoarele de gr\u0103sime trebuie verificate, golite \u0219i cur\u0103\u021bate \u00een mod regulat. Frecven\u021ba \u00eentre\u021binerii depinde de capacitatea separatorului, de cantitatea de n\u0103mol din bazin \u0219i se bazeaz\u0103, de asemenea, pe experien\u021ba de func\u021bionare \u00een condi\u021biile instala\u021biei date.<\/p>\n\n\n\n

Frecven\u021ba golirii depinde de cantitatea de ap\u0103 uzat\u0103 tratat\u0103. Camera de colectare a n\u0103molului trebuie cur\u0103\u021bat\u0103 \u00een mod regulat, de cel pu\u021bin 4 ori pe an. Separatorul \u00een sine trebuie cur\u0103\u021bat cel pu\u021bin o dat\u0103 pe an dac\u0103 nu a fost dep\u0103\u0219it nivelul admis de gr\u0103sime. Separatorul de gr\u0103sime trebuie umplut cu ap\u0103 dup\u0103 fiecare golire.<\/p>","protected":false},"excerpt":{"rendered":"
