Impahla yokupheda yebhola emisiwe iwuhlobo lwempahla yokugxusha emisiwe engenalo udaka lokuphumula, okuwumkhiqizo wakamuva othuthukiswe ezintweni eziyisisekelo eziningi zokuhlanza amanzi angcolile.
I-spherical suspension filler, eyaziwa nangokuthi i-porous rotating spherical suspension filler, iwuchungechunge lwakamuva lwemikhiqizo eyenzelwe ukwelashwa kwamanzi angcolile asekhaya kanye nobuchwepheshe bokwelashwa kwe-biofilm.Inesakhiwo esigcwele esinezinhlangothi ezintathu ekwelashweni kwe-biochemical of indle, inendawo enkulu ethize, ibekwe ngokuqondile, ayidingi ukulungiswa, kulula ukulengiswa ifilimu, futhi ayivinjiwe.
