Tataiso ea Mohato ka Mohato ea ho Fumana Tekanyo e Ntle ea PAM
Mohato oa 1: Lokisa Tharollo ea PAM
Pele o nooa, PAM e lokela ho qhibilihisoa hantle:
- Khothaletso e khothaletsoang: 0.1% - 0.2%
- Sebelisa metsi a hloekileng, a sa tieang haholo
- Hlohlelletsa butle ho qoba ho senyeha ha polymer
- Nako ea ho qhibiliha: metsotso e 30–60
Mohato oa 2: Etsa Teko ea Nkho
Teko ea nkho e bohlokoa bakeng sa ho fumana tekanyo e nepahetseng.
Mokhoa:
- Bokella disampole tse emelang metsi a litšila
- Kenya litekanyo tse fapaneng tsa PAM (mohlala, 2 ppm, 5 ppm, 8 ppm)
- Kopanya 'me u shebe ho phaphamala ha metsi
- Lumella ho lula
- Bapisa liphetho
Mohato oa 3: Hlahloba Matšoao a Tshebetso
Matšoao a bohlokoa a kenyeletsa:
- Boholo le ho teteana ha Floc
- Lebelo la ho rarolla
- Ho hlaka ho hlollang
- Bophahamo ba seretse
Mohato oa 4: Ntlafatsa Tekanyo
Fetola tekanyo ho latela lintho tse hlokometsoeng:
- Li-floc tse nyane → eketsa tekanyo
- Li-floc tse hlephileng kapa tse phaphametseng → fokotsa tekanyo
- Metsi a nang le mashala → fetola mofuta kapa kopanya le coagulant
Ho kopanya PAM le Di-Coagulant (Leano la PAC + PAM)
Litšebelisong tse ngata tsa indasteri,PAMe sebelisoa hammoho le lintho tse kopanyang mali tse kangPolyaluminum Chloride (PAC).
Hobaneng o Sebelisa PAC + PAM?
- •PAC e thibela tjhaja ya dikarolwana
- •PAM e kopanya likaroloana ho etsa li-floc tse kholoanyane
Melemo ea ho sebelisa PAC le PAM hammoho
- ✓Tšebeliso e fokotsehileng ea lik'hemik'hale kaofela
- ✓Ho lula kapele
- ✓Ho hlaka ho ntlafetseng
- ✓Ho tlosa metsi a seretse ho betere

- Mocheso o tlase o liehisa karabelo
- Tekanyo e phahameng e ka hlokahala mariha
Maemo a ho Kopanya
- Ho kopanya ho sa lekaneng → kabo e fokolang
- Ho kuta ho feteletseng → ho senyeha ha polymer
Matlo a Seretse
- Ho teteana ha seretse
- Kabo ea boholo ba likaroloana
- Dikahare tsa tlhaho
Lintlha tsena li bohlokoa haholo lits'ebetsong tsa ho tlosa metsi a litšila.
Liphoso tse Tloaelehileng Ts'ebelisong ea PAM
Ho qoba liphoso tsena ho ka ntlafatsa ts'ebetso haholo:
- Ho eketsa PAM e omileng ka ho toba metsing a litšila
- Ho sebelisa mofuta o fosahetseng oa PAM
- Teko ea ho tlola nkho
- Ho sebelisa moriana o feteletseng ho "potlakisa" kalafo
- Tokiso e mpe ea tharollo
