In Ukwelashwa kwamanzi wezimboni, ukususwa kwama-solids amisiwe kuyisixhumanisi esibalulekile. Akugcini nje ngokuthuthukisa ikhwalithi yamanzi, futhi kunciphisa ukugqoka nokuklebhula kwemishini nokuvalwa. Njengamanje, izindlela zokususa ama-solids amiswe ngokuyinhloko zibandakanya ukuqina, ukufona, ukugcwala kanye nokufakelwa. Phakathi kwazo, indlela ye-flocculation isetshenziswa kabanzi ngenxa yokusebenza kwayo okuphezulu kanye nomnotho. Kule ndlela, i-polymer ebizwa ngePolydadMac idlala indima ebalulekile.
IPolydadMac, enegama eligcwele eligcwele Yakhiwa ikakhulukazi nge-polymering diaterimethylammonium chloride monomer ngokusebenzisa i-chain yokukhula polymerization. Lokhu kulungiswa kwe-polymerization kuvame ukwenziwa ngaphansi kwe-catalysis ye-acid noma usawoti, futhi i-polymer ye-linear eqondile ingatholakala. Kuvame ukubanzi okuphuzi noma okumhlophe ku-powder ophuzi noma ama-granule. Ine-soubelity enhle futhi ingahlakazwa ngokulinganayo ezixazululweni zamanzi.
I-PolydadMacInobunzima obukhulu bokushaja futhi ngokuvamile iziphatha njenge-polymer ye-cationer. Lokhu kusho ukuthi kungenzeka ama-adsorb athuke kabi ama-solids amisiwe kanye nezinhlayiya ezihlanganisiwe emanzini ukwakha ama-flocs amakhulu, ngaleyo ndlela athole ukususwa okusebenzayo kwama-solids amisiwe. I-PolydadMac imvamisa isetshenziswa njenge-flocculant futhi i-coabulant futhi isetshenziswa kabanzi emikhakheni ehlukene yokwelashwa kwamanzi, kubandakanya nokwelashwa kwamanzi wezimboni kanye nokwelashwa kwendle kwendle. Ingakha ngokushesha ama-flocs amakhulu futhi aminyene kumanzi amdaka futhi asuse ngempumelelo ama-solids amisiwe, ama-ion anensimbi eqinile kanye nokungcoliswa kwe-organic.
Ekwelashweni kwamanzi amdaka kusuka ku-pulp kanye namaphepha okugaya, indlela yesenzo yePolydadMac ibonakala ikakhulu kulezi zinto ezilandelayo:
Hlanganisa ukungathathi hlangothi
Isenzo esishukumisayo: Njengoba i-Floc yakhiwa, izodweba ama-solids amiswe ama-solids kanye nezinhlayiya ezi-colloidal emanzi angcolile ku-floc, efinyelela ukuhlukaniswa okuqinile okuwuketshezi ngesenzo somzimba.
Umphumela we-Net-Capture: Ama-polymers aphezulu anama-polymers angakha isakhiwo senethiwekhi esiminyene, ukudonsa okumisiwe ama-solids kanye nezinhlayiya ze-colloidal kuyo njengetha lokudoba, ngaleyo ndlela kufinyelelwe ukuhlukaniswa okusebenzayo.
Uma kuqhathaniswa nezinye izindlela zokwelashwa kwamanzi, kusetshenziswa i-polydadmac yokuphatha i-pulp nephepha imfucumfucu kunezindlela ezilandelayo:
Ubuningi obukhulu bokushaja: Ubuningi obuphezulu bePolydadMac bukuvumela ukuthi bakwazi ukudonsa ngempumelelo ama-solids athuthelwe kabi ama-solids kanye nezinhlayiya ze-colloidal, ngcono ukusebenza kahle kokwelashwa.
Ukuqina okuqinile: I-PolydadMac inemiphumela emihle yokwelashwa ngezinhlobo ezahlukahlukene zePulp nePhepha wachitha amanzi futhi azithintwe ukuguquguquka kwekhwalithi yamanzi.
Ukusebenza kahle okuphezulu nokusetshenziswa okuphansi: usebenzisa i-polydadmac njengobaI-flecculontantFuthi ama-coalulant anganciphisa kakhulu umthamo wamakhemikhali, ngenkathi ethuthukisa ukusebenza kahle kokwelashwa futhi anciphise izindleko zokusebenza.
Ngobungane ngemvelo: I-PolydadMac iyi-polymer ye-cationer. I-Floc ekhiqizwa ngemuva kokusetshenziswa ayiboshelwa kalula ibe yizinto eziyingozi futhi inobungani bemvelo.
Ekuphetheni, polydadmac, njengePolymer ephezulu, inezinzuzo zokusebenza kahle okuphezulu, ukusetshenziswa okuphansi, kanye nobungani bemvelo, futhi kudlala indima ebalulekile ekwelapheni amanzi angcolile kusuka ku-pulp nasemaphepheni amamitha. Ngesikhathi lapho umkhuba wokuvikelwa kwemvelo kunzima ukumelana khona, i-polydadmac ngumkhiqizo wamakhemikhali odumile ohlangabezana nezimpawu zemikhiqizo enobungani bemvelo.
