SiC ceramic membrane muaj flux siab, siab corrosion kuj, yooj yim tu, thiab ntev kev pab cuam lub neej, ua rau nws haum rau ib tug ntau yam ntawm daim ntaub ntawv.JMFILTEC cov khoom tau ntse thov nyob rau hauv high standard purification ntawm cov dej haus, pre-kho ntawm seawater desalination, Kev sib cais thiab rov qab cov ntaub ntawv tshwj xeeb, kev kho kom sib sib zog nqus thiab rov qab siv cov dej phwj tuaj thiab cov dej khib nyiab, thiab lwm yam kev thov. Nov yog qee qhov kev tshawb fawb peb tau ua:
Case 1
Dej hiav txwv DesalinationRO kev kho mob
Lub npe qhov project: 28800 m³ / d Ningbo desalination project:
Qhov system no yog ib lub tshuab desalination nrog cov dej tso tawm ntawm 28800 m3/d. Cov dej nyoos yog muab los ntawm cov dej hiav txwv ntawm Zhejiang ntug dej hiav txwv. Cov dej uas tsim tau tsuas yog siv rau aquaculture. Cov dej zoo ua tau raws li ntau qhov ntsuas tau teev tseg hauv "Dej Zoo Standard for Desalination Products" HY/T 247-2018.
Cov dej tsim tawm ntawm lub tshuab desalination tau txais kev ua kom tsis muaj kab mob ultraviolet thiab raug thauj mus rau tus tswv dej taw tes los ntawm lub twj tso kua mis tsis tu ncua.
Ultrafiltration membrane pretreatment txheej txheem khiav daim ntawv:
Desalination txheej txheem:
Seawater → Silicon carbide tiaj daim ntawv membrane system → Silicon carbide tiaj daim ntawv membrane dej ntau lawm twj tso kua mis → Ultraviolet sterilization ntaus ntawv → Silicon carbide tiaj daim ntawv membrane dej ntau lawm pas dej ua ke → RO booster twj tso kua mis → RO kev ruaj ntseg lim → RO siab twj tso kua mis → RO ntaus ntawv (nrog rau lub zog rov qab ntaus ntawv thiab RO) → RO dej ntau lawm pas dej ua ke
Cov kua qaub-puag cov dej khib nyiab tsim los ntawm ultrafiltration thiab thim rov qab osmosis tshuaj ntxuav yog tawm tom qab neutralization los ntawm qhov nruab nrab nruab nrab.
Qhov zoo ntawm qhov project:
● Thawj cov txheej txheem luv luv desalination pretreatment project nyob rau hauv Suav teb, siv micro-coagulation + ca ceramic membrane direct filtration txheej txheem, hloov cov txheej txheem ib txwm ntxiv cov tshuaj flocculation sedimentation + xuab zeb filtration + multi-media filtration + ultrafiltration.
● Thawj silicon carbide membrane daim ntawv thov qhov project hauv aquaculture hauv Suav teb.
● Qhov loj tshaj plaws ceramic membrane daim ntawv thov qhov project rau desalination pretreatment nyob rau hauv Suav teb.
● Kev txuag hluav taws xob thiab txo qis, txuag av.
Raw dej zoo:
Cov dej nyoos ntawm qhov project no yog dej hiav txwv.
