Nangona i-originalukupakisha umalekoyeplanti yamandla ideaerator isebenzisa iileya ezisibhozo zokupakisha, kunzima ukufikelela kwimo efanelekileyo yefilim yamanzi kuba ezinye zazo zaphukile, zathambeka, kwaye zaguquguquka. Amanzi atshizwe emva kokutshizwa kokutshiza enza ukuqukuqela kwamanzi eludongeni lwedeaerator. Nangona iphinda ihanjiswe kwi-plate yokutshiza amanzi kwakhona nge-cone yokuqokelela amanzi, kunzima ukufezekisa ukuyila kwasekuqaleni kokusabalalisa ngokulinganayo amanzi kwindawo yokutshiza kwi-packing ngenxa yesakhiwo sayo (ngaphezu kwe-4,000 Φ8 imingxuma ivuliwe kwi-disc enkulu kunye nobubanzi be-1300mm). Ngenxa yesimo esibi sefilimu yamanzi, ukutshiza kwi-packing layer ayilingani, ngoko ke amanzi atshisiweyo kunye ne-steam yesibini ephezulu ayikwazi ukuphumeza ngokupheleleyo ubushushu kunye nenkqubo yokudlulisa ubuninzi, ngakumbi inkqubo yokudlulisa ubuninzi.
Iingqimba ezisibhozo kuphela zokupakisha azikwazi ukuhlangabezana neemfuno, esinye sezizathu zokuba i-deaerator inobunzulu obumpofu be-deoxygenation. Ke ngoko, la manyathelo alandelayo athatyathwa:
a) Buyisela umaleko wokupakisha owileyo, omfutshane, othambekileyo, okanye owaphukileyo;
b) Yongeza imigangatho emibini yokupakisha kwindawo encinci;
c) Gcwalisa umphezulu wetreyi yamanzi nge-mesh yensimbi engenasici ukuqinisekisa ukufana kwamathontsi amanzi atshizwe kumaleko wokupakisha.
