I-Biofiltration iyindlela yokulawula ukungcoliswa kusetshenziswa i- bioreactor equkethe izinto eziphilayo ukuze ithwebule futhi yonise ukungcola ngokwebhayoloji.Ukusetshenziswa okuvamile kufaka phakathi ukucubungula amanzi angcolile, ukuthwebula amakhemikhali ayingozi noma usilika ophuma emanzini, kanye ne- microbiotic oxidation yokungcola emoyeni. Ama-biofilters amaningi asebenzisa imidiya enjengesihlabathi, idwala elichotshoziwe, amatshe omfula, noma uhlobo oluthile lwepulasitiki noma impahla ye-ceramic emise ubuhlalu obuncane namasongo.
