Hanganga me te kaupapa o te centrifuge porowhita whakapae:
Ko te pūwero porowhita whakapae he taputapu tango porowhita. Ko te pūwero porowhita whakapae he mea hanga i te nuinga o te wā mai i te kawe porowhita me te wāhanga rerekē me ngā pahu hurihuri ōrite, te pahu ōrite e huri ana ki te pahu ki te hurihanga, me te pou hurihuri hurihuri paku iti iho. Ina wehea te whakatārewatanga o te pūwero porowhita whakapae, ka tukuna te wai whakatārewatanga ki te ngongo e te pou hurihuri tuwhera, ā, ka maka tonu te whakatārewatanga ki roto i te kōhao pahu hurihuri o te mīhini pūwero i raro i te kaha pūwero o te pahu pūwero kia huri i te hurihanga tere-teitei. I roto. Ko te pahu hurihuri tere-teitei o te pūwero porowhita whakapae i whakaputa i te kaha pūwero kaha hei maka i ngā matūriki āhua-totoka me te matotoru āhua-wai ki runga i te pakitara o roto o te pahu hei hanga i tētahi paparanga totoka (nā te mea ko te mowhiti, e kiia nei ko te paparanga mowhiti totoka) nā te matotoru he iti te kaha pūwero, nō reira ka taea anake te hanga i tētahi paparanga wai i roto i te paparanga mowhiti totoka, e kiia nei ko te paparanga mowhiti wai. Nā te rerekētanga o te tere o te porowhita me ngā pahu o te centrifuge porowhita whakapae, ka puta he nekehanga whanaunga (arā, ko te rerekētanga tere), ā, ka whakamahia e te centrifuge porowhita whakapae te nekehanga whanaunga o te porowhita me te pahu hei whakatairanga mārire i te paparanga paru o te paparanga mowhiti totoka. I te mutunga o te pahu hurihuri, ā, i muri i te haere i roto i te wāhi maroke, ka tukuna tonutia te wai o te paparanga mowhiti wai o te paparanga mowhiti wai e tohatohahia ana e te porowhita hurihuri mai i te awa o te pū wai, ka ringihia tonutia ki te pahu hei hanga i te wai wehewehe.
