Poly Aluminium Chloride e sebetsa joang?

Lefatšeng la ho hloekisa metsi,Poly Aluminium Chloride(PAC) e hlahile e le coagulant e feto-fetohang le e sebetsang hantle. Ka tšebeliso e atileng ea ho hloekisa metsi a nooang le litsi tsa ho hloekisa metsi a litšila, PAC e etsa maqhubu ka matla a eona a makatsang a ho hlakisa metsi le ho tlosa litšila. Sehloohong sena, re shebana le tšebetso ea PAC le bohlokoa ba eona tabeng ea tlhoekiso ea metsi.

Khemistri ka morao ho PAC:

Poly Aluminium Chloride ke motsoako oa lik'hemik'hale o entsoeng ka aluminium le chlorine, ka mokhoa oa AlnCl(3n-m)(OH)m. Sebopeho sa eona se feto-fetohang se bakoa ke taba ea hore e ka ba teng ka mefuta e fapaneng ho latela karo-karolelano ea aluminium-to-chloride le tekanyo ea polymerization. Liphapang tsena li lumella PAC ho ikamahanya le liphephetso tse ngata tse fapaneng tsa tlhoekiso ea metsi.

Coagulation le Flocculation:

Mosebetsi oa mantlha oa PAC kalafong ea metsi ke coagulation le flocculation. Ha PAC e eketsoa metsing a tala, e etsoa ka hydrolysis. Nakong ea ts'ebetso ena, e etsa aluminium hydroxide flocs, e sebetsang haholo ho hapa litšila tse emisitsoeng ka metsing. Li-aluminium hydroxide flocs li sebetsa joalo ka limakete tse nyane, li hohela le ho kopanya likaroloana tse kang litšila, libaktheria le lintho tse phelang.

Ho Tlosa Litšila:

PAC's coagulation-flocculation mechanism e thusa ho tloseng litšila tse fapaneng metsing, ho kenyeletsoa lintho tse tiileng tse emisitsoeng, li-colloid, esita le lintho tse ling tse qhibilihisitsoeng. Ha li-flocs li ntse li hola le ho ba boima ho feta, li lula tlase ho tanka ea kalafo ka sedimentation kapa li ts'oaroa habonolo ke li-filters. Sena se fella ka tlhahiso ea metsi a hloekileng le a hloekileng.

pH ho se nke lehlakore:

O mong oa melemo e hlokomelehang ea PAC ke ho se nke lehlakore ha pH. Ho fapana le li-coagulants tsa setso tse kang aluminium sulfate kapa ferric chloride, tse ka fetolang pH ea metsi haholo, PAC e boloka maemo a pH a batla a tsitsitse. Sena se fokotsa tlhoko ea lik'hemik'hale tse eketsehileng ho lokisa pH, ho nolofatsa ts'ebetso ea kalafo le ho fokotsa litšenyehelo.

Melemo ea ho sebelisa PAC:

Katleho: PAC e sebetsa ka mokhoa o atlehileng ho pholletsa le mefuta e mengata e fapaneng ea litšoaneleho tsa metsi le lits'ila.

Versatility: E ka sebelisoa bakeng sa kalafo ea metsi ea mantlha le ea thuto e phahameng.

Masala a Tlase: PAC e hlahisa lihlahisoa tse fokolang tsa seretse, ho fokotsa litšenyehelo tsa ho lahla.

E na le Litšenyehelo: Ho sebetsa hantle ha eona le ho se nke lehlakore ha pH ho etsa hore e be khetho e baballang chelete bakeng sa limela tsa ho hloekisa metsi.

Tšireletseho: PAC hangata e nkuoa e bolokehile ho sebetsa ho feta li-coagulants tse ling.

Likopo tsa PAC:

PAC e fumana ts'ebeliso e batsi liindastering tse fapaneng, ho kenyeletsoa tlhoekiso ea metsi ea masepala, tlhoekiso ea metsi a litšila a indasteri, esita le indastering ea pampiri le ea masela. Bokhoni ba eona ba ho tlosa mefuta e mengata ea litšila bo etsa hore e be sesebelisoa sa bohlokoahali bakeng sa ho netefatsa phepelo ea metsi a hloekileng le a sireletsehileng.

Qetellong, Poly Aluminium Chloride (PAC) ke tharollo e tsotehang ea ho hloekisa metsi e sebetsang ka ho kopanya le ho phalla. Ho sebetsa ha eona, ho feto-fetoha ha maemo, le ho se nke lehlakore ha pH li e behile e le khetho e ratoang bakeng sa lits'ebeletso tsa kalafo ea metsi lefatšeng ka bophara. Ha tlhoko ea metsi a hloekileng e ntse e hola, PAC e ntse e le karolo ea bohlokoa ho netefatsa phihlello ea metsi a bolokehileng le a nooang bakeng sa lichaba ho pota lefatše.
