Imizi-mveliso yePulp kunye nePhepha zahlulwe zibe ziinxalenye ezimbini: ukuphamba kunye nokwenza iphepha. Inkqubo yokuphamba yinkqubo apho izinto ezityebileyo kwifayibha ezifana nezinto zilungiswa, ziphekwe, zihlanjwe, zifakwe i-bleach, nezinye izinto ezifana nazo ukuze zenze i-pulp enokusetyenziswa ekwenzeni iphepha. Kwinkqubo yokwenza iphepha, i-slurry ethunyelwa kwisebe lokuphamba ifakwa kwinkqubo yokuxuba, ukugeleza, ukucinezela, ukomisa, ukujija, njl.njl. ukuvelisa iphepha eligqityiweyo. Ngaphaya koko, iyunithi yokubuyisela i-alkali ibuyisela ulwelo lwe-alkali kutywala obumnyama obukhutshiweyo emva kokuphamba ukuze lusetyenziswe kwakhona. Isebe lokunyanga amanzi amdaka liphatha amanzi amdaka emva kokwenza iphepha ukuze lihlangabezane nemigangatho efanelekileyo yokukhupha ukungcola kazwelonke. Iinkqubo ezahlukeneyo zokuveliswa kwephepha ezingasentla zibalulekile kulawulo lwevalvu elawulayo.
