Uma iqashwe kubuchwepheshe be-MBBR, Isithwali se-MBBR sifaneleka kakhulu kukho kokubili ukufakwa kwezitshalo ezintsha kanye nokuthuthukiswa kwezindawo ezikhona. Izici zayo ezihlukile kanye nezinzuzo ziyenza ilungele kokubili ukuhlanzwa kwamanzi angcolile ezimbonini nakumasipala:
● Izinto ezihlala isikhathi eside eziqinisekisa ukuphila okude
● Izinto ezinhle kakhulu ze-hydrophilic ezisiza ukunamathela kwama-microorganisms, okuholela ekwakhekeni kwe-biofilm ngokushesha.
● Indawo emagebhugebhu ekhulisa indawo ethile, ngaleyo ndlela ikhulise i-biomass
Abathwali be-MBBR babonisa ukusebenza kahle okumangalisayo ekuqedeni i-BOD, i-nitrogen, ne-ammonia. Zikulungele kakhulu ukuthuthukisa kanye nokuvuselela izindawo zokuhlanza indle, kanye nezinqubo ezithuthukisiwe zokukhishwa kwendle. Ukwengeza, lobu buchwepheshe buthola ukusetshenziswa ekwakhiweni kwemishini ehlanganisiwe, kunciphisa kakhulu indawo edingekayo yaphansi cishe ngo-1/3 kuya ku-1/2 uma kuqhathaniswa nezindlela zendabuko.
