Ishelufu yeentsika ezine kuphuculo lweshelufu yevenkile enkulu .Le shelufu ineentsika ezine ezenza ukuba ishelufu yonke izinze ngakumbi kwaye yomelele.Yenziwe ngokugoba okubandayo, ukuhluba okuzenzekelayo komgca wemveliso wokugqobhoza oqhubekayo, kwaye yamkele itekhnoloji yomgubo we-electrostatic.Sikhetha impahla ekrwada yentsimbi yeSPCC ngononophelo.Ishelufu iyonke ibukeka kakuhle, ayinamanzi kwaye ichasene nomhlwa kunye nomgubo ocolekileyo wokwaleka.Ishelufu ngokuqhelekileyo yenziwe ngamaleko ama-5.Ishelufu inokudityaniswa iishelufu eziphambili kunye nezongezelelweyo kunye nekholomu kwaye zihlanganiswe ngokulula ngaphandle kwezixhobo.Umaleko ngamnye unobubanzi obufanayo.
