Malangizo Ogwiritsira Ntchito Moyenera RO Reverse Osmosis Membrane

1. Chenjezo! Ntchito zosayenerera izi zitha kuwononga mwachindunji nembanemba ya RO reverse osmosis

Kugwira ntchito kwa nembanemba za RO reverse osmosis kumawoneka kokhazikika, koma kunyalanyaza pang'ono ntchito kungayambitse kulephera msanga, makamaka m'magulu atatu a mavuto.

Mpweya wotsalira womwe sunatulutsidwe mokwanira pansi pa kuthamanga kwambiri ungapangitse "nyundo ya pneumatic" kuwononga nembanemba

Mpweya wotsalira mkati mwa chipangizocho ukagwira ntchito pansi pa mphamvu yamagetsi, ukhoza kupanga "mphamvu ya nyundo yamadzi," yomwe imakhudza mwachindunji zinthu za nembanemba ndikuwononga thupi. Izi nthawi zambiri zimachitika m'njira ziwiri:

Zipangizo zikayambiranso, mpweya sunatsukidwe mokwanira: Mukamaliza kuchotsa zipangizo, yambaninso ntchitoyo. Ngati mpweya sunatulutsidwe kwathunthu ndipo kupanikizika kukuwonjezeka mofulumira, mpweya wotsalawo udzakhudza kwambiri nembanemba. Njira yoyenera ndikugwiritsa ntchito mphamvu yochepa ya 2 ~ 4 bar poyamba, ndikuwonjezera pang'onopang'ono kupanikizikako pokhapokha ngati thovu silikuwoneka mu flow meter (kusonyeza kuti mpweya wachotsedwa kwathunthu).

Kutseka mapaipi kosayenera kumalola mpweya kulowa: Ngati kulumikizana pakati pa zida zokonzeratu (monga microfilter) ndi pampu yamphamvu kwambiri kwatuluka kapena sikunatsekedwe bwino, madzi osakwanira okonzeratu (monga kuchepa kwa madzi chifukwa cha kutsekeka kwa microfilter) kumapangitsa kuti paipiyo ituluke mpweya, zomwe zimapangitsa kuti mpweya uyamwe. Njira zothetsera vutoli ndi monga kuyeretsa kapena kusintha microfilter yotsekeka, kuyang'ana ndi kukonza mapaipi otulutsa mpweya, ndikuwonetsetsa kuti palibe mpweya wolowa panthawi yogwira ntchito.

2. Njira yolakwika yotseka imayambitsa kukula kwa filimu ndi kuipitsidwa

Anthu ambiri amakhulupirira kuti "kutseka = kuzimitsa nthawi yomweyo," koma izi zitha kusiya zoopsa zobisika pa nembanemba za RO, makamaka zokhudzana ndi nkhani ziwiri:

Kuchepetsa kuthamanga kwa magazi popanda kutsuka kungayambitse kukula kwa madzi m'mbali mwa madzi: Pa nthawi ya ntchito ya RO membrane, kuchuluka kwa madzi m'mbali mwa madzi kumakhala kwakukulu kwambiri kuposa m'madzi odyetsera. Ngati kuthamanga kwa magazi kutsika mofulumira mukatseka popanda kutsuka bwino, madzi m'mbali mwa madziwo amamatira pamwamba pa madzi, zomwe zimapangitsa kuti madziwo azitsekeka zomwe zimatseka ma pores a madzi m'mbali mwa madzi ndikuchepetsa mphamvu zosefera pakapita nthawi.

Tsukani ndi madzi okhala ndi mankhwala ophera tizilombo: Ena amagwiritsa ntchito madzi ophera tizilombo ophera tizilombo toyambitsa matenda, zomwe sizikulimbikitsidwa. Panthawi yomwe zipangizo sizikugwira ntchito, madzi okhala ndi mankhwala ophera tizilombo amatha kuchitapo kanthu ndi madziwo kapena kusiya zotsalira zomwe zimadetsa madziwo, zomwe zingakhudze ubwino wa madzi otuluka m'thupi.

3. Kusakonza bwino ndi kupha tizilombo toyambitsa matenda kungayambitse "kufalikira" kwa tizilombo toyambitsa matenda m'thupi.

Zinthu zopangidwa ndi polyamide zomwe zimapezeka mu RO nembanemba ndi zomwe anthu ambiri amagwiritsa ntchito, koma zili ndi vuto: kukana bwino mankhwala ophera tizilombo monga chlorine. Ngati mankhwala ophera tizilombo monga chlorine sanagwiritsidwe ntchito bwino panthawi yogwira ntchito, kuphatikizapo kusayang'anira bwino kuipitsidwa ndi tizilombo toyambitsa matenda, mabakiteriya ndi tizilombo toyambitsa matenda m'madzi zimafalikira pamwamba pa nembanemba, zomwe zimapangitsa kuti pakhale ma biofilms. Izi sizimangotseka ma pores a nembanemba komanso zimayambitsa kuipitsidwa kwa tizilombo toyambitsa matenda m'madzi otuluka (chifukwa chachikulu cha kuchuluka kwa tizilombo toyambitsa matenda m'madzi oyera omwe opanga ambiri amapanga chili pano).
