• Zoyambira Zochizira Madzi Momwe mungasankhire nembanemba ya RO yoyenera

Kusankhidwa ndi kufananitsa koyenera kwa nembanemba za RO kumatsimikizira kuthekera koyambira kwa zida za RO, ndipo pali mitundu yambiri ya ma membrane a RO pamsika, ndipo mitengo imakhalanso yosiyana kwambiri. Kupatulapo magawo ochepa kwambiri a ma membrane apadera omwe ali ndi mtengo wowonjezera waukadaulo (kusefukira kwamitengo), mitengo yamakanema a RO azinthu wamba, zitsanzo ndi zochitika zogwiritsira ntchito za opanga ambiri zakhala zowonekera komanso zokhazikika. Nthawi zambiri, mtengo wa nembanemba wa RO wotumizidwa kunja ndi wokwera mtengo pang'ono kuposa wamtundu wa RO wapakhomo, koma uli ndi maubwino pang'ono pokhudzana ndi kukhazikika, moyo wautumiki, zizindikiro zazikulu (kutsika kwa mchere, kutulutsa madzi, kuchira) ndi zina zotero.

• Mtundu wa malonda (chithunzi cha ntchito):

Ultra-low pressure membrane element: ultra-low pressureRO nembanemba chinthu akhoza kusankhidwa kwa lolowera madzi TDS≤1000mg/L (ppm), amene ali oyenera mchere ndende chakudya kupanga, madzi tapala, kukonzekera madzi koyera, madzi ulimi wothirira, siteji yachiwiri madzi a magawo awiri nembanemba dongosolo ndi ntchito zina mafakitale.

Ultra-low pressure membrane element: ultra-low pressureRO membrane element itha kusankhidwa kuti ikhale ndi madzi olowera TDS≤1500mg/L, omwe ndi oyenera kuthira mchere ndi madzi apampopi am'matauni ndi pansi ngati madzi osaphika.

• Mitundu yosiyanasiyana yogwiritsira ntchito

XLP mndandanda: otsika kwambiri kuthamanga nembanemba chinthu, ambiri oyenera zochizira magwero otsika mchere madzi ndi otsika mchere zofunika mlingo otsika desalination, monga madzi pamwamba, pansi, madzi apampopi ndi tauni madzi ndi mchere zili zosakwana 1000ppm, makamaka oyenera gawo lachiwiri desalination wa magawo awiri n'zosiyana osmosis nyambo. Amagwiritsidwa ntchito kwambiri m'magawo osiyanasiyana monga madzi oyeretsedwa a masikelo osiyanasiyana, madzi opangira boiler, kukonza chakudya ndi mafakitale opanga mankhwala.

ULP mndandanda: kopitilira muyeso-otsika kuthamanga nembanemba chinthu, ambiri oyenera desalination mankhwala a pamwamba madzi, pansi, madzi apampopi ndi tapala madzi ndi mchere zili za 2000ppm kapena zochepa, makamaka ntchito mmatumba madzi, madzi akumwa, kukatentha madzi kukazinga, processing chakudya ndi makampani opanga mankhwala ndi madera ena.

• Zambiri za reverse osmosis membrane

Mlingo wokanidwa mchere: Mlingo wa kutulutsa mchere wa chinthu cha nembanemba cha RO udadziwika panthawi yomwe imapangidwa, ndipo kuchuluka kwa mchere kumatengera kuchuluka kwa gawo lochotsa mchere lomwe lili pamwamba pa gawo la RO nembanemba, kuchulukira kwa gawo lotulutsa mchere, kukwezeka kwa kuchuluka kwa mchere, komanso kutsika kwamadzi. Mlingo wa desalination wa RO nembanemba pazinthu zosiyanasiyana umatsimikiziridwa ndi kapangidwe kake ndi kulemera kwazinthu, kuchuluka kwa desalination kwa ayoni apamwamba-valent ndi ma ion zovuta monovalent kumatha kupitilira 99%, komanso kuchuluka kwa ma ion a monovalent monga ayoni a sodium, ayoni potaziyamu, ndi ayoni a chloride ndi otsika pang'ono, koma amathanso kupitilira nthawi yochepera 98% ya mankhwala. Kuchotsa mchere wa RO nembanemba) Mlingo wochotsa zinthu zachilengedwe zolemera kwambiri kuposa 100 ukhozanso kupitilira 98%, koma kuchuluka kwa zinthu zomwe zili ndi molekyulu yolemera zosakwana 100 ndizotsika.

Njira yowerengera kuchuluka kwa kukana mchere komanso kutsekemera kwa mchere wa RO membrane:

Kuthekera kwa mchere wa RO nembanemba = RO nembanemba imadutsa ndende / mphamvu yamadzi × 100%

Mlingo wa desalination wa RO nembanemba = (mchere womwe uli m'madzi amadzimadzi / mchere wamadzi amphamvu a 1-RO membrane) × 100%

Kupanga Madzi: GPD = Magaloni (US)/Tsiku, GFD = Ma Galoni (US)/pa sikweya phazi/tsiku

Kuchuluka kwa madzi a RO nembanemba - kumatanthawuza mphamvu yotulutsa madzi ya RO system, mwachitsanzo, kuchuluka kwa madzi omwe amadutsa mumtundu wa RO pa nthawi, nthawi zambiri amawonetsedwa mu matani pa ola kapena magaloni patsiku. 1 galoni (US) = malita 3.785, 1 kiyubiki mita = 264.2 magaloni (US).

Kuthekera kwa nembanemba ya RO ndichizindikiro chofunikira cha zokolola zamadzi za RO membrane element. Imatanthawuza kuchuluka kwa kuthamanga kwa permeate pagawo la nembanemba ya unit, yomwe nthawi zambiri imawonetsedwa mu magaloni pa sikweya phazi patsiku (GFD). Kuthamanga kwambiri kwa osmotic kumapangitsa kuti madzi azithamanga kwambiri pamwamba pa nembanemba ya RO, zomwe zimakulitsa kuwonongeka kwa nembanemba.

Kupanikizika (kuthamanga kwambiri kwa ntchito): 1 kg kuthamanga = 1 bar ≈ 14.5 psi = mutu 10m (pampu)

PSI (mapaundi pa sikweya inchi) ndi gawo la kuyeza. P amatanthauza mapaundi, S amatanthauza masikweya, ine amatanthauza mainchesi, ndipo United States amagwiritsidwa ntchito pogwiritsira ntchito psi monga unit, kutanthauza mphamvu ya mapaundi pa inchi imodzi.

Kuthamanga kwa ma membrane a RO nthawi zambiri kumakhala pakati pa 2-20MPa, kutengera zinthu monga mtundu, kukula, zinthu, ndi mtundu wamadzi wa chinthu cha membrane. Nthawi zambiri, kukhathamiritsa kwa magwiridwe antchito a nembanemba ya RO, kumapangitsanso kutulutsa mchere, komanso kumawonjezera chiwopsezo cha kuvala kwa zinthu komanso kuwonongeka kwa nembanemba. Chifukwa chake, kupanikizika kogwira ntchito kwa nembanemba ya RO kuyenera kuwongolera mkati mwazoyenera kuti zitsimikizire kukhazikika kwake ndi moyo

Pakugwiritsa ntchito, mphamvu yogwiritsira ntchito ma membrane a RO iyenera kusinthidwa malinga ndi mtundu wamadzi komanso zofunikira zamankhwala. Mwachitsanzo, pakuchotsa mchere m'madzi a m'nyanja, mphamvu yogwira ntchito ya nembanemba ya RO nthawi zambiri imakhala pakati pa 5-10MPa kuti ikwaniritse bwino komanso kukhala ndi moyo wautali. Pochiza madzi otayira m'mafakitale, ma membrane a RO amatha kugwira ntchito movutikira kwambiri kuti athe kuthana ndi zovuta zamadzi komanso kuchuluka kwa mchere wambiri.

Mlingo Wochira: Kuchira kwa membrane wa RO - kumatanthauza kuchuluka kwa madzi a chakudya mumtundu wa RO womwe umasinthidwa kukhala permeate kapena permeate. Zimatsimikiziridwa molingana ndi mtundu wamadzi omwe amadziwikiratu komanso zofunikira zamadzi za RO system. Kubwezeretsa kwa dongosolo la membrane la RO kumatsimikiziridwa panthawi yopangidwira.
Mlingo wobwezeretsa wa nembanemba ya RO = (kuthamanga kwamtundu wa RO membrane / kutuluka kwamphamvu) × 100%
