Cov ntaub ntawv ua haujlwm txhua hnub ntawm qhov rov qab osmosis system yog lub hauv paus tseem ceeb rau kev txiav txim siab tias lub kaw lus tsis muaj kuab paug thiab cov txheej txheem kev tu kom huv yog tom qab kev ua qias tuaj.
Kev tswj cov kab mob rov qab osmosis yuav tsum them sai sai rau cov ntaub ntawv kaw cia.
Thaum tu, nws yuav tsum tu kom huv raws li txoj cai tu tsev ntawm thim rov qab osmosis membrane.
Cov tsos mob thiab tu kab mob sib kis tsawg
Cov kab mob microbial feem ntau tshwm sim thaum lub sijhawm kaw ntawm cov thim rov qab osmosis system. Hauv qhov rov qab osmosis system uas siv cov dej saum npoo av, cov dej rov qab (cov dej qias neeg), dej hiav txwv, thiab lwm yam zoo li cov khoom siv dej, microbial paug yog feem ntau nrog cov pa phem. Kev paug cov roj ntsha yuav tsum tu kom huv lub sijhawm thaum pib theem. Thaum lub biofilm tsim, nws yog qhov nyuaj heev kom ntxuav, thiab tsuas yog lub membrane daim nyias nyias yuav tsum tau hloov.
Cov Lus Taw Qhia: Siv cov tshuaj tiv thaiv kab mob rau cov txheej txheem rau cov kab mob uas tau ntxim rau cov kab mob me me, thiab tsim kom tsis muaj kab mob los ntawm kev ntxiv NaCLO thiab lwm cov fungicides rau hauv dej mus rau hauv cov khoom siv membrane, thiab yuav tsis muaj kev sib kis me me.
1. Cov tsos mob ntawm kev kis me me
A. Kev muaj kuab paug tshwm sim rau txhua ntu, thiab lub siab sib txawv ntawm thawj ntu thiab ntu thib ob tuaj yeem nce nrawm;
B. Txo cov dej hauv cov dej tsim tawm;
C. Cov kev coj ua ntawm cov dej tsim tawm tsis yog hloov pauv;
D. Qhov tseem ceeb tshwm sim yog nce siab sib txawv.
2. Thaum cov kab mob me me tshwm sim, nws tuaj yeem ntxuav tau raws li cov qauv hauv qab no:
| Lub ntsiab paug | Pom zoo ntxuav kua dej | Cov lus ceeb toom |
| Cov kab mob me | 0.1 % sodium hydroxide (NaOH) + 0.025 % sodium dodecylbenzene sulfonate (Na-DDBS) | Tshaj li, huv nrog (NaOH) thiab (Na-DDBS), PH=12, siab tshaj 30 30 |
| 0.1% sodium hydroxide (NaOH) | Tshaj li, ntxuav nrog (NaOH) ， PH=12, siab tshaj 30 ℃ | |
| 2.0 % sodium tripolyphosphate (STPP) + 0.025 % sodium dodecylbenzene sulfonate (Na-DDBS) | Nyiam dua, huv nrog (Na5P3O10) (Na-DDBS), PH=10, siab tshaj 30 ℃ |
Tom qab cov tshuaj ntxuav tu cov thim rov qab osmosis membrane nrog cov kab mob sib kis tau, qhov system yuav tsum tau muab tshuaj tua kab mob los txhim kho qhov kev tiv thaiv kab mob ua ntej kom tsis txhob muaj cov paug me me.
