Ulayini wokukhiqiza iyogathi uthuthukisiwe ukuze kuqinisekiswe inqubo yokuvubela elawulwayo ebalulekile ekwenzeni iyogathi yekhwalithi ephezulu enokuvumelana okubushelelezi nokunokhilimu. Kusukela ekulawuleni okunembayo kwezinga lokushisa kuya ekuphathweni ngokucophelela kwamasiko abukhoma, sonke isiteji siklanyelwe ukusekela umsebenzi ofanelekile we-microbial kanye nokuthuthukiswa kokuthungwa. Lezi zinhlelo ezizenzakalelayo zigcina inhlanzeko nokungaguquguquki, okuvumela ukukhiqizwa kwesilinganiso esikhulu ngaphandle kokuphazamisa ukunambitheka noma inani lokudla okunempilo. Kungakhathaliseki ukuthi ukhiqiza izinhlobo ezilula noma ezinambithekayo, umugqa uqinisekisa ukufana, ukuqina kweshalofu, nokuthungwa okucebile okulindelwe abathengi.
