1. Zosefera za granular: mphamvu yaikulu ya mtengo- kusefa moyenera
Zosefera za granular ndiye mtundu womwe umagwiritsidwa ntchito kwambiri pazosefera, zomwe zimatsuka madzi kudzera pakutsatsa komanso kutsekereza. Mitundu yodziwika bwino ndi:
1). Mchenga wa Quartz: kukula kwa tinthu 0.5-1.2mm, asidi amphamvu ndi kukana zamchere, mtengo wotsika, womwe umagwiritsidwa ntchito popangira madzi akumwa komanso kuchimbudzi (onani "Industrial Water Treatment Technology Manual").
2). Mpweya woyatsidwa: wogawidwa kukhala chipolopolo cha malasha ndi kokonati, chokhala ndi porosity yofikira 500-1500m²/g (gwero la deta: US Environmental Protection Agency EPA), imatha kugulitsa zinthu zachilengedwe ndi zitsulo zolemera, zoyenera zoyezera madzi ndi kuyeretsa mpweya.
3). Anthracite: kachulukidwe kochepa (1.4-1.6g/cm³), kuphatikizidwa ndi mchenga wa quartz kuti azitha kusefera bwino, zomwe zimagwiritsidwa ntchito kwambiri m'matanki amitundu iwiri.
Kuipa kwa zosefera za granular ndikuti ndizosavuta kuphatikizika ndipo zimafunikira kutsukidwa pafupipafupi, ndi moyo wazaka pafupifupi 3-5.
2. Fiber fyuluta zakuthupi: kusankha koyenera komanso kusefa kwabwino
Zosefera za CHIKWANGWANI zimapangidwa ndi zinthu zosinthika komanso kusefa kwambiri. Mitundu yoyimilira ndi:
1). Ulusi wa polypropylene: wosachita dzimbiri-wosamva, ukhoza kupangidwa kukhala chinthu chosefera thonje cha PP, pore 1-10μm, chomwe chimagwiritsidwa ntchito posefera zisanadze zoyeretsera madzi a m'nyumba.
2). Magalasi CHIKWANGWANI: kutentha kugonjetsedwa (zosachepera kapena zofanana ndi 280 digiri), nthawi zambiri amagwiritsidwa ntchito pochiza zinyalala za gasi zamafakitale, monga dongosolo lamagetsi la desulfurization.
3). Ceramic CHIKWANGWANI: kuphatikiza tinthu ndi CHIKWANGWANI makhalidwe, mphamvu kukana, oyenera mkulu mamasukidwe akayendedwe madzi kusefera mu makampani mankhwala.
Kuipa kwa fiber filter material ndi mphamvu yochepa, yosavuta kuthyoka pakatha-nthawi yaitali, ndipo imayenera kusinthidwa pafupipafupi.
3. Zosefera za membrane ndi zida zomwe zikutuluka: kugwiritsa ntchito ukadaulo wapamwamba
1). Zida zosefera ma membrane:
- Membala ya Microfiltration (0.1-10μm): chotsani mabakiteriya ndi zinthu zomwe zaimitsidwa, monga kusefa kwa zotsukira madzi m'nyumba.
- Nembanemba ya Ultrafiltration (0.01-0.1μm): imatha kuthana ndi ma virus ndipo imagwiritsidwa ntchito kwambiri pochiza dialysis (onani "Membrane Separation Technology Application Guide").
2). Porous ceramic filter media: High temperature resistant (>1000 digiri), kugonjetsedwa ndi dzimbiri, koma mtengo wapamwamba, womwe umagwiritsidwa ntchito kwambiri pakuyeretsa kutentha kwa gasi mumakampani opanga zitsulo.
3). Zosefera zatsopano zophatikizika: monga graphene zosinthidwa zosefera, mphamvu yotsatsa imachulukitsidwa nthawi zopitilira 3 (kafukufuku wa "Nature Materials" 2022), koma sinagulitsidwebe pamlingo waukulu.
4. Kodi kusankha bwino fyuluta TV?
Kuwunika kwathunthu kutengera zolinga zosefera (monga kuchotsa turbidity, sterilization, decolorization), katundu wamadzimadzi (pH mtengo, kutentha) ndi bajeti yamtengo. Mwachitsanzo:
- Kuphatikizika kwa "quartz sand + activated carbon" kumagwiritsidwa ntchito kwambiri muzomera zam'madzi;
- Madzi osayera kwambiri pamakampani opanga zamagetsi amayenera kufananizidwa ndi zosefera za membrane;
- Makanema akusefera a Ceramic ndi omwe amakonda kuwotcha mpweya wotentha kwambiri.
M'tsogolomu, pamene mfundo zoteteza zachilengedwe zikuwongoleredwa, -zochita bwino kwambiri komanso{1}}zosefera zautali zamoyo zonse zidzakhala zomwe zidzachitike pa kafukufuku ndi chitukuko.
