Tšebeliso ea Reverse Osmosis Membrane le Theknoloji e Amanang le Phekolo ea Metsi
- Phekolo ea metsi a litšila
Phekolo ea metsi a litšila ke ts'ebeliso ea mantlha ea li-membrane tsa reverse osmosis. Ka theknoloji ea reverse osmosis, tšepe e boima kapa oli e nang le metsi a litšila e hlahisoang ke lifeme tsa motlakase le lifeme tsa khatiso le ho daea li ka phekoloa hantle. E ka boela ea sebelisoa ho phekola likhoerekhoere tsa litoropo, litšila tsa lithōle, joalo-joalo, ho finyella ho hlaphoheloa ha mehloli ea metsi.
Ts'ebetsong ea ho hlahisa matla a mocheso, ho sebelisoa metsi a mangata a pholileng a potolohang, ao hangata a nang le litšila tse sa tšoaneng le moferefere o phahameng. Haeba e lahleloa ka kotloloho, e tla baka tšilafalo tikolohong. Motsoako oa li-membrane tse se nang letho tsa fiber ultrafiltration le membrane ea polyamide composite reverse osmosis e ka tšoara metsi a pholileng a potolohang ka har'a metsi a ka sebelisoang hape a nang le moferefere oa metsi ka tlase ho 0.02 NTU le index ea tšilafalo e ka tlase ho 0.7.
Metsi a litšila a hlahisoang ke lifeme tsa khatiso le tse daeang a na le li-ion tse ngata tsa letsoai, li-ion tsa mebala le lintho tse ling. Tšebeliso ea ultrafiltration le reverse osmosis dual membrane technology e ka sefa lintho tse phelang, li-ion tsa letsoai, joalo-joalo metsing a litšila, 'me tšebeliso ea lik'hemik'hale ea oksijene ea metsi a hlahisoang ha e phahametse 10 mg / L, e leng se bontšang phello e kholo ea phekolo ea metsi.
Mekhoeng ea setso ea ho hloekisa metsi a litšila a nang le litšepe tse boima, ho hlokahala hore ho eketsoe lisebelisoa tsa lik'hemik'hale, 'me litlhoko tsa ts'ebetso ea phekolo li phahame. Tšebeliso ea li-membrane tsa reverse osmosis le thekenoloji ea multistage reverse reverse osmosis ho hloekisa metsi ana a litšila ho ka tlosa ka katleho likarolo tsa tšepe tse boima tse ka metsing a litšila.
Likarolo tse fumanehang ka har'a litšila tsa litoropong li ngata ebile li rarahane. Tšebeliso ea polyamide reverse osmosis membrane bakeng sa phekolo ea eona e ka hloekisa leachate ea litšila ho fihlela boemong ba ho qhala, ho finyella phekolo ea leachate ea litšila.
- Tlhahiso ea metsi a hloekileng
Metsi a hloekisitsoeng a na le mefuta e mengata ea tšebeliso ea metsi a nooang a malapeng, tlhahiso ea indasteri le meriana. Lisebelisoa tsena li na le litlhoko tse phahameng tsa metsi, 'me tšebeliso ea li-membrane tsa reverse osmosis bakeng sa phekolo ea metsi e hloka ho latela litekanyetso tse hlokahalang tsa tlhahiso.
Ka lebaka la ts'ebetso e batlang e holile ea tlhahiso ea metsi a ultrapure, likarolo tsa membrane tse lumellanang li ka sebelisoa ho hlahiseng metsi a ultrapure. Sistimi ea reverse osmosis e ka laola phallo ea metsi ho fihla ho 650 m ³/h le ho hlahisa metsi a ultrapure ka conductivity ea 0.3 m S/cm. Bothata ba ho silafala ha membrane nakong ea kalafo ea metsi bo ka rarolloa ka mekhoa ea ho hloekisa lik'hemik'hale. Sistimi ea kalafo ea metsi a hloekileng e sebelisoang hajoale ke reverse osmosis electrodeionization system.
Mabapi le tlhahiso ea metsi a indasteri, molemong oa ho fihlela tlhoko ea ts'ebeliso, bafuputsi ba malapeng ba hlahisitse tharollo ea ho aha sistimi ea reverse osmosis e sebelisang likarolo tsa membrane tsa "ultra-low pressure roll". Tlhahiso e le 'ngoe ea metsi a lera la lesela le phunyeletsang morerong ona e ka fihla ho 41.4 cubic metres ka letsatsi, ka tekanyo ea ho boloka e seng ka tlase ho 99.7%, e ka finyellang ka botlalo tlhokahalo ea metsi ea tlhahiso ea indasteri ea caustic soda.
Ntle le moo, tlhahiso ea indasteri ea chlor alkali, hoa hlokahala ho sefa Ca ² ⁺ le Mg ² ⁺ li-ion metsing nakong ea tlhahiso. Ka hona, PVD reverse osmosis membrane e ka sebelisoa ho li tlosa, ha e ntse e netefatsa sekhahla se tlase sa ho boloka sodium chloride, ho fihlela kalafo ea metsi le tlhoekiso tlhahisong ea indasteri ea chlor alkali.
Tlhahisong ea meriana, ho sebelisa ultra-low pressure polyamide composite permeable membrane module ion separation system le ho sebelisa mokhoa oa mekhahlelo e 'meli oa reverse osmosis ho hlahisa metsi a hloekileng a hlokahalang ts'ebetsong ea tlhahiso ea meriana e ka finyella liphello tse ntle tsa tlhahiso. Sekema sena sa tlhoekiso ea metsi se na le sekhahla sa ho hlaphoheloa se seng ka tlase ho 80% ka mor'a hore reverse osmosis ea bobeli, e tlisang melemo e mengata ea moruo ho lik'hamphani tsa meriana.
