Inkqubo yeMveliso

Ityhubhu engqukuva billet → ukufudumeza → ukugqobhoza → ukuqengqeleka okuqengqelekayo okuthathu, ukuqengqeleka okuqhubekayo okanye ukukhulisa → ukuhluba → ukulinganisa (okanye ukunciphisa ubukhulu) → ukupholisa → ukolula → uvavanyo lolwelo loxinzelelo lwehydraulic (okanye ukubhaqwa kwempazamo) → ukumakisha → ukugcina.

Indawo yosetyenziso

Umbhobho wensimbi ongenamthungo onzima usetyenziswa ikakhulu kwindawo yokugcina amanzi, i-petrochemical, ikhemikhali, amandla ombane, ukunkcenkceshela kwezolimo, ukwakhiwa kwedolophu kunye namanye amashishini.Kuthutho lwamanzi: unikezelo lwamanzi kunye nokukhupha amanzi.Ukuthuthwa kwerhasi: irhasi yendalo, umphunga, igesi yepetroleum engamanzi.Ukusetyenziswa kolwakhiwo: isetyenziswa njengebhulorho yokugobela imibhobho;amadokhi, iindlela, izakhiwo kunye nezinye izakhiwo.
