Hang ha tšilafalo ea likaroloana le colloid e etsahala ho reverse osmosis kapa nanofiltration system, e ka ama haholo tlhahiso ea metsi ea lera 'me ka linako tse ling ea fokotsa sekhahla sa ho ntša letsoai. Matšoao a pele a ho silafatsoa ha colloidal ke ho eketseha ha phapang ea khatello ea tsamaiso, 'me mehloli ea likaroloana kapa li-colloid ka har'a mohloli oa metsi a kenang lera a fapana ho ea ka libaka, hangata ho akarelletsa le libaktheria, sludge, colloidal silicon, lihlahisoa tsa tšepe tsa tšepe, joalo-joalo Lithethefatsi tse sebelisoang karolong ea pele ho phekolo, joalo ka polyaluminum le ferric chlorication kapa ferric chloride e ka 'na ea boela ea e-ba teng. e tlositsoe hantle ka tanka ea ho hlakisa kapa filthara e mahareng. Ho feta moo, cationic polymeric dielectrics e ka boela ea itšoara ka li-anionic scale inhibitors, 'me li-precipitates tsa tsona li ka silafatsa likarolo tsa lera. SDI15 e sebelisetsoa ho lekola tšekamelo ea ho silafatsoa ho joalo kapa kalafo pele ho metsi. Ka kopo sheba kenyelletso e qaqileng likhaolong tse amehang.

14. Nako e kae e lumelletsoeng ea ho koala ntle le ho hlatsuoa ha sistimi?

Haeba tsamaiso e sebelisa li-scale inhibitors, ha mocheso oa metsi o le pakeng tsa 20-38 ℃, ho nka lihora tse ka bang 4; Hoo e ka bang lihora tse 8 ka tlase ho 20 ℃; Haeba sistimi e sa sebelise li-scale inhibitors, ho tla nka letsatsi le le leng.

15. Tšebeliso ea matla ea tsamaiso ea membrane e ka fokotsoa joang?

Likarolo tse tlase tsa tšebeliso ea matla li lekane, empa hoa lokela ho hlokomeloa hore sekhahla sa bona sa desalination se tlase hanyane ho feta sa li-membrane tse tloaelehileng.

E ka feta ka bolokolohi ka har'a lera la microfiltration, le sebelisetsoang ho tlosa libaktheria, li-micro flocs, kapa lihlahisoa tse emisitsoeng kaofela (TSS). Khatello e tloaelehileng mahlakoreng ka bobeli a lera ke 1-3 bar

16.Na tsamaiso ea metsi a hloekileng ea reverse osmosis e ka qala le ho emisa khafetsa?

Sistimi ea membrane e entsoe ho ipapisitse le ts'ebetso e tsoelang pele, empa ts'ebetsong ea 'nete, ho tla lula ho e-na le maqhubu a itseng a ho qala le ho koala. Ha tsamaiso ea membrane e koetsoe, hoa hlokahala ho sebelisa metsi a eona a hlahisitsoeng kapa metsi a hloekisitsoeng esale pele bakeng sa ho phalla ka khatello e tlase ho nka sebaka sa metsi a mangata a nang le li-scale inhibitors tse tsoang likarolong tsa lera. Mehato e boetse e lokela ho nkuoa ho thibela ho tsoa ha metsi ka har'a sistimi le ho kenya moea, joalo ka ha karolo e dutla 'me ea omella, e ka baka tahlehelo e ke keng ea khutlisoa ea phallo ea tlhahiso ea metsi. Haeba ho koala ho le ka tlase ho lihora tse 24, ha ho hlokahale ho nka mehato ea ho thibela kholo ea likokoana-hloko. Empa haeba nako ea ho koala e feta melaoana e boletsoeng ka holimo, mokelikeli o sireletsang o lokela ho sebelisoa bakeng sa ho boloka tsamaiso kapa ho phalla ka nako ea tsamaiso ea membrane.

17.Ho tseba joang hore na tataiso ea ho kenya mehele ea ho koala metsi a letsoai holim'a likarolo tsa membrane?

Lesale la ho tiisa metsi a letsoai holim'a membrane element ho hlokahala hore e kenngoe qetellong ea ntho e kenang, 'me lesoba le shebane le tataiso ea ho kena. Ha sekepe sa khatello se tletse metsi, ho buloa ha eona (molomo oa molomo) ho tla tsoela pele ho buleha, ho tiisa ka ho feletseng ho phalla ha metsi ho tloha karolong ea membrane ho ea leboteng le ka hare la sekepe sa khatello.

18.U ka tlosa silicon joang metsing?

Silicon ka metsing e teng ka mefuta e 'meli: silicon e sebetsang (silicon ea monomeric) le silicon ea colloidal (polysilicon): silicon ea colloidal ha e na litšobotsi tsa li-ion, empa e na le tekanyo e batlang e le khōlō. Colloidal silicon e ka ts'oaroa ka mekhoa e metle ea ho sefa ea 'mele, joalo ka reverse osmosis, mme bokahare ba metsi bo ka fokotsoa ka theknoloji ea coagulation, joalo ka litanka tsa tlhakiso ea coagulation. Leha ho le joalo, mahlale a karohano a itšetlehileng ka litšoaneleho tsa tefiso ea ion, joalo ka li-resin tsa phapanyetsano ea ion le lits'ebetso tse tsoelang pele tsa electrodeionization (CDI), li na le katleho e fokolang ea ho tlosa silicon ea colloidal.

Boholo ba silicon e butsoitseng bo nyane haholo ho feta ba silicon ea colloidal, ka hona, mahlale a mangata a ho sefa a 'mele joalo ka tlhakiso ea coagulation, filtration, le air flotation ha e khone ho tlosa silicon e kentsoeng. Mekhoa e ka khonang ho tlosa silicon e kentsoeng hantle e kenyelletsa reverse osmosis, phapanyetsano ea ion, le electrodeionization e tsoelang pele.
