Sehlopha sa bafuputsi ba Machaena se entse tsoelo-pele e kholo ea ho hloekisa metsi a litšila ka ts'ebeliso e atlehileng ea theknoloji ea UV/E-Cl ho fokotsa litšila tsa membrane. Thuto, e sa tsoa hatisoa kaTlhaho Puisano, e totobatsa mokhoa o mocha oa ho ntlafatsa ts'ebetso ea ho ntša metsi le ts'ebetso ea ho hloekisa membrane lits'ebetsong tsa ho hloekisa metsi a litšila.
Katleho e Ntlafetseng ea ho Dewatering
Boithuto bo bonts'itse hore ts'ebeliso ea UV/E-Cl e ntlafalitse phallo ea metsi haholo litekong tsa ho tlosa metsi, ho fihlela phallo ho fihla ho 138% ea sistimi ea E-Cl, 239% ea sistimi ea UV, le 198% ea taolo. Sena se fana ka maikutlo a hore UV/E-Cl e senya ka nepo meaho e litšila, e lebisang ts'ebetsong e ntlafalitsoeng ea ho ntša metsi. Ka ho sebelisa sistimi ea mohlala ea SA-BSA, bafuputsi ba khonne ho etsisa boits'oaro bo rarahaneng ba extracellular polymeric substance (EPS) le ho netefatsa bohlokoa ba liprotheine le li-polysaccharides ho hloekisoa ha metsi a litšila (WAS).
Litlhaloso tsa Limolek'hule ka Mekhoa ea ho Fouling
Boithuto bo ile ba lekola litšebelisano tsa limolek'hule tsa liprotheine le li-polysaccharides, ho senola hore borokho ba motlakase lipakeng tsa lihlopha tsa amino le carboxyl bo bapala karolo ea bohlokoa ho silafatseng lera. Ka tlhahlobo ea pono ea FTIR le lipapiso tsa Density Functional Theory (DFT), bafuputsi ba khethile mekhoa e meraro e tlamang ea limolek'hule, e bonts'ang khetho e matla ea likhokahano tsa mela tse khothaletsang khokahano ea polymer. Liphuputso tsena li fana ka kutloisiso ea boemo ba limolek'hule ea kamoo UV/E-Cl e senyang litšebelisano tsena kateng, e lebisang ho fokotseng viscosity, boholo bo boholo ba floc, le ho ntlafatsa ho lokolloa ha metsi.
Karolo ea Synergistic ea Cl Radicals ho Phokotsong ea Fouling
Litlhahlobo tse ling li bonts'itse hore li-radicals tsa chlorine (Cl•) li na le seabo se seholo ho fokotseng BSA le SA, 'me li tlatselitse ho feta 90% ho senyeha ha tsona. Boithuto bona bo tlalehile maemo a phahameng ka ho fetesisa a karabelo e phahameng bakeng sa litšebelisano tsa Cl• le li-macromolecules tsena, tse tšehetsang katleho ea UV/E-Cl ho bolileng ha li-foulants. Ts'ebetso ena ha ea ka ea arola feela meaho ea SA-BSA hore e be likaroloana tse nyane empa hape e ile ea fokotsa matla a bona a viscosity le hydration, ka hona, ea fokolisa lera le litšila le kang la gel.
Thermodynamic Insights: Boemo ba ho etsahala ha Metsi e le Ntho ea Bohlokoa
Patlisiso e ile ea tsoela pele ho hlahloba thermodynamics ea fouling ea membrane, e tiisang hore ho hlaha ha metsi ho bolela - ho fapana le maemo a tloaelehileng a porosity kapa permeability - a laola boitšoaro bo bobe ba li-gel. Tlhahlobo ea Thermogravimetric e senotse hore metsi a tlanngoeng ka har'a likarolo tse litšila e batla e le 80%, athe kalafo ea UV/E-Cl e theoletse tlase ho 10%. Phetoho ena e ile ea lumella hore metsi a lokolloe habonolo, a qetelle a theola khanyetso ea ho sefa le ho ntlafatsa bokhoni ba ho sefa.
Ho ea ho Lisebelisoa tse Sebetsang
Ka liphetho tsena tse qobellang, bafuputsi ba fana ka maikutlo a ho ntlafatsa liparamente tsa reactor, ho kenyeletsoa lisebelisoa tsa elektrode, matla a UV, le nako ea kalafo, ho matlafatsa ts'ebetso ea scalability. Boithuto bona bo boetse bo sisinya ho kopanngoa ha UV/E-Cl le li-oxidants tse ling, joalo ka hydrogen peroxide, ho matlafatsa tlhahiso e matla le ho ntlafatsa katleho ea kalafo. Ho phaella moo, bafuputsi ba hatisa monyetla oa ho sebelisa litharollo tsa NaCl tse tlaase-concentration-tse kang metsi a leoatle-ho fumana phekolo ea metsi a litšila e tsitsitseng le e theko e tlaase.
Katleho ea Bokahohle ho Membrane Technology
Leha phuputso ena e entsoe ho sebelisoa WAS, liphuputso tsa eona li na le litlamorao tse kholo ho feta ho hloekisa metsi a litšila. Kamohelo ea ho hlaha ha metsi e le eona ntho e ka sehloohong phokotsong ea pholiso ea membrane e na le bohlokoa ba bokahohle ho pholletsa le mekhoa e fapaneng ea li-membrane le sekala sa reactor. Katleho ena e bula tsela bakeng sa theknoloji e sebetsang hantle le e tsitsitseng ea ho hloekisa indastering ea ho hloekisa metsi lefatšeng ka bophara.
Ka tlhoko e ntseng e eketseha ea lefats'e ea taolo e nepahetseng ea metsi a litšila, theknoloji ea UV/E-Cl e fana ka tharollo e ts'episang ea ho ntlafatsa bophelo bo bolelele ba membrane, ho fokotsa litšenyehelo tsa ts'ebetso, le ho ntlafatsa ts'ebetso ea kalafo ka kakaretso. Ha bafuputsi ba ntse ba tsoela pele ho ntlafatsa le ho eketsa mokhoa ona o mocha, bokamoso ba ho hloekisa metsi a litšila bo shebahala bo sebetsa hantle le bo tsitsitseng.

Ho hloekisoa ha metsi ka mokhoa o Sebetsang le oa Eco-Friendly Sludge ka Holly's Technology
Lefapheng la ho hloekisa metsi, Holly o ikemiselitse ho fana ka litharollo tse ncha tsa ho tlosa seretse ho bareki ba rona. HLDS ea rona ea Multi-disc Sludge Dewatering Screw Press, e nang le moralo o ikhethang o se nang li-clog le ts'ebetso e tsoetseng pele ea ho itlhoekisa, e fokotsa haholo litšenyehelo tsa kaho ea limela tsa likhoerekhoere. Sesebelisoa sena se sebelisa sistimi ea taolo ea othomathike ea PLC, e kopanyang screw le mehele e tsamaisang bakeng sa ho itlhoekisa, e ka nkang mochini oa khatiso oa setso joalo ka lebanta le mochini oa foreimi. Ha ho bapisoa le li-centrifuges, HLDS e sebetsa ka matla a tlaase le tšebeliso ea metsi, e leng se etsang hore e sebetse hantle le ho boloka tikoloho.
HLDS Sludge Dewatering Screw Press e sebelisoa haholo lits'ebetsong tse fapaneng tsa ho hloekisa metsi a litšila, ho kenyeletsoa masepala, petrochemical, fiber ea lik'hemik'hale, ho etsa pampiri, meriana, letlalo le likarolo tse ling tsa ho hloekisa metsi liindasteri. E boetse e sebetsa hantle bakeng sa ho alafa moiteli oa Dairy Farm, Palm Oil Sludge, Septic Sludge, le tse ling. Lisebelisoa tsa rona li netefalitsoe lits'ebetsong tse ngata tsa lefats'e la 'nete, tse bonts'ang ts'ebetso e ikhethang le melemo ea moruo, ho thusa likhoebo ho fokotsa litšenyehelo tsa ts'ebetso ha li ntse li fihlela sepheo sa tikoloho.
Ha thekenoloji ea ho hloekisa metsi e ntse e tsoela pele ho fetoha, litharollo tse ncha tsa Holly li fa bareki lefats'e ka bophara lisebelisoa tse sebetsang hantle le tse bolokang chelete e ngata, tse kenyang letsoho ntlafatsong e tsitsitseng ea indasteri ea ho ntša metsi a litšila le ea ho hloekisa metsi. Ka motsoako oa theknoloji e tsoetseng pele le boiphihlelo ba lilemo tsa indasteri, Holly o ikemiselitse ho fana ka lisebelisoa tse tsoetseng pele ka ho fetisisa tsa ho hloekisa metsi a litšila, tsoelo-pele ea indasteri le ts'ireletso ea tikoloho.
