Kamoo PAC e Ntlafatsang Bokgoni ba Phekolo ea Metsi a Liindasteri

Sebakeng sa kalafo ea metsi ea indasteri, ho batla litharollo tse sebetsang hantle le tse sebetsang ke habohlokoa haholo. Mekhoa ea indasteri hangata e hlahisa metsi a mangata a litšila a nang le lintho tse tiileng tse emisitsoeng, lintho tse phelang le litšila tse ling. Phekolo e sebetsang hantle ea metsi ke ea bohlokoa eseng feela bakeng sa ho latela melao empa hape le bakeng sa ts'ebetso e tsitsitseng.Aluminium chloride e ngata(PAC) e bapala karolo ea bohlokoa ts'ebetsong ena ka ho nolofatsa ho hoama le ho flocculation, e leng mehato ea bohlokoa ea ho arola litšila ho metsi.

Poly aluminum chloride ke k'hemik'hale e sebetsang ka ho feto-fetoha ea phekolo ea metsi e sebetsang haholo-holo e le coagulant. Coagulants e nolofalletsa ho senyeha ha likaroloana tsa colloidal ka metsing, e li lumellang ho kopana ho ba li-floc tse kholoanyane, tse boima tse ka tlosoang habonolo ka ho senngoa kapa ho sefshoa. Sebopeho se ikhethang sa PAC, se khetholloang ka marang-rang a rarahaneng a li-polymer tsa aluminium oxyhydroxide, se e nolofalletsa ho theha li-floc tse kholoanyane le tse teteaneng ha li bapisoa le li-coagulant tse tloaelehileng tse kang aluminium sulfate.

Melemo ea Bohlokoa ea ho Sebelisa PAC Phekolong ea Metsi a Liindasteri

Ho Ntlafatsa ho Kopana le ho Tsamaisana ha Metsi

PAC e na le thepa e phahameng ea ho kopanya ha e bapisoa le lintho tse kopanyang tsa setso joalo ka aluminium sulfate. Sebopeho sa eona sa polymeric se lumella ho bokellana ka potlako ha likaroloana tse tšesaane, ho etsa li-floc tse kholoanyane le tse teteaneng. Sena se lebisa ho senyeheng le ho sefa ho sebetsang hantle, ho fellang ka metsi a hlakileng haholoanyane.

Katleho ea Mefuta e Meholo ea pH

E 'ngoe ea melemo ea bohlokoa ea PAC ke bokhoni ba eona ba ho sebetsa ka katleho holim'a mefuta e mengata ea pH (5.0 ho isa ho 9.0). Sena se etsa hore e lokele ho phekola mefuta e fapaneng ea metsi a litšila a indasteri ntle le ho hloka tokiso e kholo ea pH, e bolokang nako le litšenyehelo tsa ts'ebetso.

Bophahamo ba Lerōle bo Fokolitsoeng

PAC e hlahisa seretse se fokolang ha e bapisoa le lintho tse ling tse kopanyang metsi, kaha e hloka litekanyo tse tlase le thuso e fokolang ea lik'hemik'hale ho fihlela liphetho tse lakatsehang. Sena ha se fokotse feela litšenyehelo tsa ho sebetsana le seretse le ho se lahla empa hape se fokotsa tšusumetso ea tikoloho ea ts'ebetso ea kalafo.

Bokgoni bo Ntlafetseng ba ho Sefa

Ka ho hlahisa di-floc tse hlophisitsweng hantle, PAC e ntlafatsa tshebetso ya ditsamaiso tsa ho sefa tse theohelang tlase. Metsi a hlwekileng a tswang mohatong wa ho sefa a eketsa nako ya bophelo ba di-filter mme a fokotsa ditlhoko tsa tlhokomelo.

Tšebeliso e Tlase ea Lik'hemik'hale

Bokgoni bo phahameng ba PAC bo bolela hore ho hlokahala dikhemikhale tse fokolang ho fihlella diphetho tse ntle ka ho fetisisa. Sena se fetolela ho boloka ditjeo le phokotso ya tshusumetso e ka bang teng tikolohong ya dikhemikhale tse setseng metsing a hlwekisitsweng.

Litšebeliso tsaPAC ho Phekolo ea Metsi a Liindasteri

PAC e sebelisoa liindastering tse fapaneng, ho kenyeletsoa:

Indasteri ea Masela:Ho tlosa didae le ditshila tsa tlhaho metsing a ditshila.

Tlhahiso ea Pampiri:Ho ntlafatsa ho hlaka le ho tlosoa ha mebala metsing a ts'ebetso.

Oli le Khase:Ho hlwekisa metsi a hlahisitsoeng le ho hloekisa lithōle.

Lijo le Lijo tse Nooang:Ho netefatsa hore ho latela melao e thata ea ho ntša thepa.

Ha liindasteri li ntse li loanela ho amohela mekhoa e metle, PAC e hlahella e le khetho e tsitsitseng. Bokhoni ba eona ba ho sebelisa litekanyo tse tlase, tlhahiso e fokotsehileng ea seretse, le bokhoni ba ho hokahana hantle le litsamaiso tse teng tsa kalafo li tsamaisana le lipheo tsa ho fokotsa tšebeliso ea mehloli le ho fokotsa litšila.

Ka ho kenyelletsa PAC lits'ebetsong tsa kalafo ea metsi, liindasteri li ka finyella likhoerekhoere tse hloekileng, tsa latela melao ea tikoloho, le ho kenya letsoho mekhoeng ea tsamaiso ea metsi e tsitsitseng. Bakeng sa liindasteri tse batlang ho ntlafatsa litsamaiso tsa tsona tsa kalafo ea metsi, PAC e fana ka tharollo e tšepahalang le e pakiloeng ho fihlela litlhoko tsa liphephetso tsa sejoale-joale tsa tlhoekiso ea metsi.
