Ina ia lafoa'i pe toe fa'aogaina le Lafoa'i pe a mae'a Togafitiga, e mana'omia le fa'aogaina o vaila'au eseese ile fa'agasologa ole Togafitiga ole Lafoa'i.I aso nei,PAM (Polyacrylamide) fa'atau oloao le a taʻu atu ia te oe e uiga i flocculants:
Flocculant: O nisi taimi e taʻua foi o le coagulant, e mafai ona faʻaaogaina e avea o se auala e faʻamalosia ai le vavae ese o le sua-suavai, ma e mafai ona faʻaaogaina i tane faʻamautu muamua, tane faʻamautu lona lua, tane fuʻa, togafitiga maualuga poʻo togafitiga faʻasolosolo ma isi fesoʻotaʻiga.
Flocculants o loʻo faʻaaogaina e fai ma auala e faʻamalosia ai le vavaeeseina o le sua-suavai i le fanua o le faʻaogaina o otaota.E mafai ona fa'aaogaina e fa'amalosia ai le fa'apalapala muamua o le otaota, togafitiga fa'afefeteina ma le fa'apalapala lona lua pe a uma ona fa'agaoioia le palapala palapala, ma e mafai fo'i ona fa'aoga mo togafitiga maualuga po'o togafitiga fa'asolosolo ole otaota.Pe a fa'aogaina mo le fa'asa'oina a'o le'i fa'amamaina le tele o le palapala, o mea fa'afefete ma coagulants e avea ma mea fa'apalapala po'o ni mea e fa'amama ai le suavai.
Pe a faʻaaogaina flocculants masani, o le auala o le faʻaopoopoina o fesoasoani coagulant e mafai ona faʻaogaina e faʻaleleia ai le aafiaga flocculation.Mo se fa'ata'ita'iga, o le fa'aogaina o le silicic acid fa'agaoioi e fai ma fesoasoani fa'amalo mo fugala'au fa'aonanā e pei ole ferrous sulfate ma le alumini sulfate ma fa'aopoopo i ai ile fa'asologa e mafai ona maua ai le fuga lelei.O le mea lea, i faaupuga a le tagata, o le inorganic polymer flocculant IPF ua saunia moni lava e ala i le tuʻufaʻatasia o le coagulant fesoasoani ma le flocculant ona faʻaopoopoina lea e faʻafaigofie ai le faʻaogaina o le tagata faʻaoga.
Coagulation togafitiga e masani lava ona tuu i luma o le nofoaga tuueseeseina malo-suavai, ma tuufaatasi ma le nofoaga tuueseeseina, e mafai ona aveesea lelei sologa ma mea colloidal ma se vaega itiiti o le 1nm i le 100μm i le vai mata, faaitiitia effluent turbidity ma CODCr, ma e mafai ona fa'aoga ile fa'agaioiga muamua ole fa'agasologa ole fa'amama otaota.Togafitiga, togafitiga faʻasolosolo, e mafai foʻi ona faʻaaogaina mo togafitiga faʻamaʻi.Coagulation togafitiga e mafai foi ona aveese lelei microorganisms ma pathogenic siama i le vai, ma aveese emulsified suauu, chroma, uʻamea mamafa ions ma isi filogia i otaota.Ole fua o le aveeseina ole phosphorus o lo'o i totonu ole otaota e mafai ona maualuga ile 90% pe a fa'aogaina le fa'apalapala e togafitia ai le phosphorus.~ 95%, o le auala sili ona taugofie ma sili ona lelei o le aveeseina o phosphorus.
I le faʻagasologa o le faʻaogaina o otaota, o le a faʻaaogaina isi vailaʻau.I aso nei, o leFaumea PAMna o le tasi o latou na faailoa mai.O e malamalama pea?Faʻalogo lelei i le Yuncang ma tali atili faʻamaʻi faʻamaʻi otaota mo oe!
