Libakeng tsohle tsa kalafo ea metsi a litšila moo kalafo ea likokoana-hloko e etsoang teng, pula e theoa nako le nako, e leng mokato o mong oa seretse le seretse. Ka hona, ho hlokahala letsatsi le letsatsi ho e tlosa ka litanka tsa lits'ebeletso tsa kalafo.

Haeba mahlale a morao-rao a sebelisa litanka tsa mantlha tsa sedimentation, joale ha nako e ntse e tsamaea, mokelikeli o bokellana butle-butle botlaaseng ba ona, e leng boima bo matla ba tšilafalo. Ka nako e tšoanang, bophahamo ba modumo ea bona e ka ba ka karolelano ea 2-5% ea ts'ebeliso ea letsatsi le letsatsi ea lisebelisoa tsohle.

Tsela ea ho felisa pula

Ho etsa kalafo ea seretse le ho li lahla ha bona ke ts'ebetso e thata, hobane mongobo o phahameng o sitisa motsamao oa bona, o sa khoneheng moruong haholo. Mokhoa o sebetsang ka ho fetisisa oa ho fokotsa bongata ba litšila tse tiileng ke ho nosetsa metsi, kapa ka mantsoe a mang, ho fokotsa mongobo oa bona. Sena se ka fokotsa haholo litšenyehelo tsa ho li lahla.

Ho etsa sena, sebelisa lisebelisoa tsa sejoale-joale ka sebopeho sa dehydrator ea screw. Li lokiselitsoe ka ho khetheha liteisheneng bakeng sa ho itokisa le litekanyetso tsa lintho tse hlokahalang.

Mochini o fepelang metsi a auger o khona ho sebetsana le mefuta eohle ea seretse se entsoeng nakong ea kalafo ea metsi a litšila. Ka lebaka la boholo ba eona bo kopaneng le boima bo tlase, screw dehydrator e ka beoa sebakeng se seng le se seng sa kalafo ea likhoerekhoere.

Sesebelisoa sena se khona ho sebetsa ka mokhoa o iketsang ntle le boteng ba basebetsi ba haufi le sona.

Moralo oa Dehydrator:

  • 1) pelo ea sesebelisoa kaofela ke moropa o nosetsang, o etsang botenya le ho noka ha sludge e tiileng;
  • 2) dosing tank - ho tloha ntlheng ena karolo e itseng ea mobu e kenella ka tankeng ea flocculation ka mofuta oa phallo e bopehileng joaloka V;
  • 3) flocculation tank - karolong ena ea screw dehydrator, sludge e kopantsoe le reagent;
  • 4) phanele ea taolo - ka lebaka la eona, o ka laola sesebelisoa ka mokhoa o iketsang kapa oa pukwanana.
    Seteishene sa ho hlophisa tharollo le tefiso ea tsona.

Morero oa eona ke ho lokisa li-flocculants ka metsing ka mokhoa o iketsang u sebelisa phofshoana ea granular. Ntle le moo, e le khetho, e ka ba le pompo ea phepelo, sensor ea ho omella ea reagent e fanoeng le pompo bakeng sa tharollo e lokiselitsoeng.
