ukuhlanza-umjikelezo-kanye{2}}nezinyathelo zokuqapha{3}}zo{4}}zokushisa-nokushintshisana
Imishini yokudlulisa ukushisa iqukethe isishintshi sokushisa, iphampu yokujikeleza, namapayipi. Ukuhlanza ngokuyinhloko kususa isikali, i-sediment, nama-microorganisms ukuvimbela ukuvala nokunciphisa ukusebenza kahle kokushisa. Ukuze uthole izinga elihle lamanzi, ukuhlanza kungenziwa minyaka yonke; emanzini aqinile noma ukungcola okuphezulu, kungase kudingeke ukuhlanzwa njalo, njengakanye ezinyangeni eziyisithupha. Kodwa-ke, abasebenzisi bangadinga ukuqondiswa okuqondile, njengokuthi unganquma kanjani ukuthi ukuhlanza kuyadingeka noma izincomo ezimweni ezahlukahlukene.
Lapho uhlanza isishintshi sokushisa samanzi-kuya{1}}kumanzi, imininingwane ebalulekile ihlanganisa ukuvala iyunithi ukuze ihlanzwe ukugwema ukulimaza amashubhu okushintshanisa ukushisa. Sebenzisa i-ejenti yokuhlanza efanele, njengesixazululo esine-asidi noma esine-alkaline, kodwa naka ukugxilisa ingqondo nezinga lokushisa ukuze uvimbele ukugqwala. Hlanza kahle ngemva kokuhlanza ukuze ugweme i-ejenti yokuhlanza eyinsalela. Ukwengeza, kungase kudingeke ukuthi kuhlolwe ukuvuza noma ukushintsha izingxenye.
