Mahinga matua me nga waahanga hanganga:

I raro i te mahi o te whakamahana hau wera me te hurihanga i roto i te wahanga oumu, ko te kiriata whakawehe CH:Cl on

ko te mata, ko te wahanga o te hau karehu ka whakapoapoa hei wai, ka whakamahia tetahi wahi o te hau hiku karekau

te whakamaroke hau whakamaroke, a ko tetahi atu waahanga ka tukuna ki te punaha whakaora hau hiku.Ka whiriwhiri motuhake tatou

he waro whakahohe anga kokonati, he painga o te kaha whakaurunga CH₂Cla nui, teitei

efficieney purenga me te hydrophobicity pai.I roto i te ahua o te tank adsorption whakapae, te uta waro

he nui te kaha, he teitei te ngawari o te mahi, ko te kukū hau hiku o CH: Cla he iti iho i te 20mg/m', a

ko te tere whakaora he nui ake i te 99.97%.
