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 kokutshiza akwenza umpompozo wamanzi eludongeni lwedeaerator. Nangona iphinda isasazwe kwipleyiti yokutshiza amanzi kwakhona ngekhowuni yokuqokelela amanzi, kunzima ukufezekisa uyilo lwangaphambili lokusasaza ngokulinganayo amanzi kumaleko okutshiza kwipakethe ngenxa yobume bayo (ngaphezu kwe-4,000 Φ8 imingxuma ivuliwe kwi idiski enkulu enobubanzi obuyi-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.
