Izixhobo zokucocwa kwamanzi amdaka asekhaya ezingenamandla (itanki yendalo esingqongileyo)

Amanzi amnyama kuqala angena kwi-tank ye-septic yangaphambili yonyango lwangaphambili, apho i-scum kunye ne-sediment ibanjwe, kwaye i-supernatant ingena kwicandelo lonyango lwe-biochemical yesixhobo. Ithembele kwii-microorganisms emanzini kunye nesigcwalisi sebhedi ehambayo emva kokuba i-membrane ixhonywe unyango, i-hydrolysis kunye ne-asidi ithobisa into ephilayo, ukunciphisa i-COD, kunye nokwenza i-ammonification. Emva kokunyangwa kwe-biochemical, i-sewage igeleza kwicandelo lonyango lomzimba we-backend. Izinto ezikhethiweyo zokucoca ezisebenzayo zijolise kwi-adsorption ye-ammonia nitrogen, ukuhluthwa kwezinto eziqinileyo ezimisiweyo, ukubulawa kwe-Escherichia coli, kunye nezixhobo ezixhasayo, ezinokuqinisekisa ukucuthwa okusebenzayo kweCOD kunye ne-ammonia nitrogen kumanzi amdaka. Ngokwesiseko sokuhlangabezana nemigangatho yokunkcenkceshela esisiseko, iimfuno eziphezulu zinokufikelelwa. I-backend inokuxhotyiswa ngetanki yamanzi acocekileyo eyongezelelweyo ukuqokelela kunye nokucocwa kwamanzi omsila, ukuhlangabezana neemfuno zokusetyenziswa kobutyebi kwimimandla yasemaphandleni.
