Flocculant e sebetsa joang ho hloekisa metsi?

Li-flocculantse bapala karolo ea bohlokoa ho hloekisoeng ha metsi ka ho thusa ho tlosa likaroloana tse emisitsoeng le li-colloid metsing.Mokhoa ona o kenyelletsa ho thehoa ha li-flocs tse khōloanyane tse ka lulang kapa tsa tlosoa habonolo ka ho hloekisa.Mona ke kamoo li-flocculants li sebetsang kateng ho hloekisa metsi: 

Li-flocculants ke lik'hemik'hale tse kentsoeng metsing ho thusa ho bokellana ha likaroloana tse nyenyane, tse senyehileng hore e be lihlopha tse kholoanyane, tse khonang ho tlosoa habonolo tse bitsoang li-flocs.

Mefuta e tloaelehileng ea li-flocculants e kenyelletsa li-coagulants tsa inorganic joalo kaPolymeric Aluminium Chloride(PAC) le ferric chloride, hammoho le li-organic polymeric flocculants tse ka bang li-polymer tsa maiketsetso tse kang polyacrylamide kapa lintho tsa tlhaho tse kang chitosan.

Coagulation:

Pele ho flocculation, coagulant e ka kenyelletsoa ho senya likaroloana tsa colloidal.Li-coagulants li fokotsa litefiso tsa motlakase ho likaroloana, li li lumella ho kopana.

Li-coagulant tse tloaelehileng li kenyelletsa polymeric aluminium chloride, aluminium sulfate (alum) le ferric chloride.

Flocculation:

Li-flocculants li kenngoa ka mor'a hore li kopane ho khothalletsa ho thehoa ha lihlopha tse kholoanyane.

Lik'hemik'hale tsena li sebelisana le likaroloana tse senyehileng, li etsa hore li kopane 'me ka potlako li thehe lihlopha tse khōloanyane, tse bonahalang.

Sebopeho sa Floc:

Ts'ebetso ea flocculation e etsa hore ho thehoe lihlopha tse kholoanyane le tse boima tse lulang ka potlako ka lebaka la boima bo eketsehileng.

Ho theha Floc ho boetse ho thusa ho ts'oara litšila, ho kenyelletsa le lintho tse tiileng tse emisitsoeng, libaktheria le litšila tse ling.

Ho lokisa le ho hlakisa:

Hang ha li-flocs li se li thehile, metsi a lumelloa ho lula ka sekotlolo sa sedimentation.

Nakong ea ho lokisa, li-flocs li lula fatše, li siea metsi a hlakileng ka holimo.

Sefa:

Bakeng sa tlhoekiso e eketsehileng, metsi a hloekisitsoeng a ka 'na a kenngoa tlas'a filtration ho tlosa likaroloana leha e le life tse setseng tse ntle tse sa kang tsa lula.

Ho bolaea likokoana-hloko:

Ka mor'a ho phalla, ho lula le ho sefa, metsi a atisa ho phekoloa ka likokoana-hloko tse kang chlorine ho felisa likokoana-hloko tse setseng le ho netefatsa tšireletso ea metsi.

Ka kakaretso, li-flocculants li sebetsa ka ho fokotsa tefiso ea likaroloana tse emisitsoeng, ho khothalletsa ho bokellana ha likaroloana tse nyenyane, ho etsa lihlopha tse khōloanyane tse lulang kapa li ka tlosoa habonolo, tse lebisang ho metsi a hlakileng le a hloekileng.
