Momwe Mungawunikire Kachitidwe ka Reverse Osmosis Membranes?

Reverse osmosis (RO) nembanemba, monga chigawo chachikulu chazida zochizira madzi, amagwira ntchito yofunika kwambiri m'magawo ambiri chifukwa cha magwiridwe antchito, otsika mtengo, komanso okonda zachilengedwe. Ndi kupita patsogolo kosalekeza kwaukadaulo komanso kuwonekera kwa zida zatsopano, ukadaulo wa reverse osmosis ukuthana pang'onopang'ono ndi zovuta zosiyanasiyana zochizira madzi, kupatsa anthu madzi otetezeka komanso okhazikika. Kupyolera mu kusanthula mozama, zikuwonekeratu kuti nembanemba ya RO ili ndi malo ofunikira kwambiri pazamankhwala amadzi. Sikuti zimangokweza miyezo yaubwino wa madzi komanso zimayendetsa zatsopano komanso kupita patsogolo kwaukadaulo wamankhwala amadzi wonse. Motsogozedwa ndi chidziwitso chochulukirachulukira cha kasungidwe ka madzi, kugwiritsa ntchito ukadaulo wa reverse osmosis kudzafalikira, zomwe zikuthandizira kwambiri kugwiritsa ntchito bwino madzi padziko lonse lapansi.

Momwe Mungawunikire Kachitidwe ka Reverse Osmosis Membranes? Nthawi zambiri, magwiridwe antchito a reverse osmosis (RO) amayezedwa ndi zisonyezo zitatu zazikulu: kuchuluka kwa kuchira, kuchuluka kwa madzi opangira madzi (ndi flux), komanso kukana mchere.

1. Kuchira Mlingo

Mlingo wochira ndi chizindikiro chofunikira kwambiri cha magwiridwe antchito a nembanemba ya RO kapena dongosolo. Zimayimira gawo la madzi odyetsa omwe amasandulika kukhala madzi opangidwa (madzi oyeretsedwa). Njirayi ndi:Kubwezeretsanso (%) = (Chitundu Choyenda Mlingo wa Madzi ÷Kudyetsa Madzi Oyenda) × 100

2. Madzi Opangira Madzi ndi Flux

Kuchuluka kwa Madzi opangira madzi: Kumatanthawuza kuchuluka kwa madzi oyeretsedwa opangidwa ndi nembanemba ya RO pa nthawi ya unit pansi pa zovuta zinazake. Magawo wamba akuphatikizapo GPD (magalani patsiku) ndi LPH (malita pa ola).

Flux: Imawonetsa kuchuluka kwa madzi opangidwa pagawo lililonse la nembanemba pa nthawi ya unit. Mayunitsi nthawi zambiri amakhala GFD (magaloni pa sikweya phazi patsiku) kapena m³/m²·tsiku (ma kiyubiki mita pa lalikulu mita patsiku).

Chilinganizo: Mtengo Wopangira Madzi = Flux × Malo Ogwira Ntchito A Membrane

3. Mlingo Wokana Mchere

Kuchuluka kwa kukana mchere kumawonetsa kuthekera kwa areverse osmosis (RO)nembanemba kuchotsa zonyansa m'madzi. Nthawi zambiri, kutulutsa bwino kwa nembanemba za RO pazoyipa zenizeni kumatsata njira izi:

Kukana kwakukulu kwa ayoni a polyvalent poyerekeza ndi ma ion a monovalent.

Mlingo wochotsa ma ion ovuta ndi apamwamba kuposa ma ion osavuta.

Kuchepetsa kuchotsera bwino kwa ma organic compounds okhala ndi mamolekyu olemera osakwana 100.

Kuchepetsa mphamvu yolimbana ndi zinthu zamagulu a nayitrogeni ndi mankhwala ake.

Kuphatikiza apo, kuchuluka kwa kukana mchere kumagawidwa m'mitundu iwiri:

Mlingo Wowonekera Wokana Mchere:

Mlingo Wowonekera Wokana (%) = 1-(Chinthu Chothira Mchere Wothira Mchere / Dyetsani Kuthira kwa Mchere wa Madzi)

Mlingo Weniweni Wokana Mchere:

Mlingo Weniweni Wokanidwa (%) = 1-2xProduct Madzi Othira Mchere / (Dyetsani Madzi Othira Mchere + Kusunga Mchere)] ÷2×A

A: Concentration polarization factor (nthawi zambiri kuyambira 1.1 mpaka 1.2).

Metric iyi imayang'ana bwino momwe membrane imagwirira ntchito pochotsa zonyansa pansi pa zochitika zenizeni padziko lapansi.

Timapereka mitundu yonse yazida zochizira madzi, Zogulitsa zathu zimaphatikizapo zida zofewetsa madzi, zida zoyeretseranso madzi, zida zoyeretsera madzi a UF, ultrafiltration UF zida zoyeretsera madzi, zida zochotsera madzi am'nyanja, zida za EDI zamadzi opitilira muyeso, zida zoyeretsera madzi otayira ndi zida zopangira madzi.
