Membrane Yatsopano ya RO Siikugwira Ntchito?

Chifukwa chiyani RO Membrane Yatsopano Sikugwira Ntchito?Tiyeni tikambirane zifukwa ndi mayankho pansipa:

1. Kutentha kwamadzi olowera ndikotsika kwambiri:
Kutentha kogwira ntchito kwa nembanemba ya reverse osmosis ndi 25 ℃, ndipo kupanga madzi kumatsika ndi 3% nthawi iliyonse kutentha kutsika ndi digiri imodzi.Ngati kutentha kuli kochepa kuposa 0 ° C, madzi osaphika amaundana ndipo mwachibadwa sangathe kutulutsa madzi bwinobwino.

2. Kuthamanga kwa madzi olowera ndikotsika kwambiri:
Mfundo yogwirira ntchito ya nembanemba ya reverse osmosis ndikusefa ndi kukakamiza.Ngati pampu yolimbikitsa ikugwiritsidwa ntchito kwa nthawi yayitali, mphamvu yolowera imatsika, ndipo madzi osaphika sangathe kukwaniritsa zofunikira, zomwe zimapangitsa kuti madzi asatuluke mu reverse osmosis system.Nthawi zambiri, kukakamizidwa kogwira ntchito kwa nembanemba ya reverse osmosis kumafunika kufikira 4.14MPA.

3. Mphamvu pH
Mitundu yosiyanasiyana ya ma membrane a RO imakhala ndi pH yovomerezeka, ndipo pH yamadzi okhudzidwa ilibe mphamvu pakupanga ma tater.Koma ngakhale mkati mwazovomerezeka, zimakhudza kwambiri kukana mchere.Kumbali imodzi, mtengo wa pH umakhalanso ndi vuto linalake pamayendedwe amadzi opangira.Izi ndichifukwa choti nembanemba ya reverse osmosis yokha imakhala ndi magulu ena ogwira ntchito, ndipo pH yamtengo imatha kukhudza nembanemba.Munda wamagetsi pamtunda nawonso umakhudza kusamuka kwa ayoni.Phindu la pH limakhudza mwachindunji mawonekedwe a zonyansa zomwe zimakhudzidwa.Mwachitsanzo, kwa dissociable organics, kukana kutsika kumachepa ndi kuchepa kwa pH.Komano, chifukwa CO2 kusungunuka m'madzi kwambiri anakhudzidwa ndi pH mtengo, pamene pH mtengo ndi otsika, alipo mu mawonekedwe a mpweya CO2 ndipo mosavuta likulowerera n'zosiyana osmosis nembanemba.Choncho, mlingo wokana mchere umakhala wotsika pamene pH mtengo uli wochepa.Pamene pH ikuwonjezeka, mpweya wa CO2 umasinthidwa Kwa HCO-3 ndi CO2-3 ions, kukana mchere kumawonjezeka pang'onopang'ono, ndipo kukana mchere kumafika pamwamba kwambiri pakati pa pH 7.5 ndi 8.5.

4. Mphamvu mchere ndende
Kuthamanga kwa Osmotic ndi ntchito ya kuchuluka kwa mchere kapena organic kanthu m'madzi.Mchere wochuluka kwambiri, kuthamanga kwa osmotic kumawonjezeka.Pamene kulowetsedwa kolowera kumakhalabe komweko, kuthamanga kwa ukonde kudzachepa ndipo kupanga madzi kudzachepa.Kutsekemera kwa mchere kumayenderana ndi kusiyana kwa mchere pakati pa kutsogolo ndi kumbuyo kwa nembanemba.Kuchuluka kwa mchere wokhudzidwa, kumapangitsanso kusiyana kwakukulu, ndipo kuchuluka kwa mchere kumawonjezeka, zomwe zimabweretsa kuchepa kwa kukana mchere.Kwa dongosolo lomwelo, madzi amchere amchere amasiyana, kuthamanga kwa ntchito ndi ma conductivity a madzi azinthu ndizosiyana.Pachiwonjezeko chilichonse chamchere wamchere ndi 100 ppm, kuthamanga kwamadzi olowera kumafunika kukwera pafupifupi 0.007 MPa.Pa nthawi yomweyo, chifukwa cha kuchuluka kwa ndende, mankhwala madzi madutsidwe Komanso kuchuluka moyenerera.

5. Kutsekeka koyambirira:
Ma membrane am'mbuyo a osmosis amakhala ndi zofunika kwambiri pakumwa madzi, ndipo zida zoyenera zochizira, monga zosefera mchenga wa quartz, zosefera zachitetezo, ndi zina zambiri, nthawi zambiri zimawonjezedwa pamaso pa zinthu za nembanemba.Ngati chikugwiritsidwa ntchito kwa nthawi yayitali, chipangizocho chikhoza kutsekedwa chifukwa cha zonyansa zambiri.Pambuyo potsekeka, padzakhala kutsika kwina kwa kupanga madzi.Pamene pretreatment zonyansa kwathunthu oletsedwa, madzi yaiwisi sangathe kulowa n'zosiyana osmosis nembanemba kudzera pretreatment, ndiye n'zosiyana osmosis The nembanemba adzaoneka otchedwa palibe madzi.

6. Chovala chotchinga chatsekedwa:
Panthawi yogwiritsira ntchito, valavu yowunikira ikhozanso kutsekedwa ndi zonyansa.Mukhoza kutenga valve yowunikira kuti muwone ngati kupanga madzi kwadongosolo kwawonjezeka kwambiri.Nthawi zambiri, mwayi wotsekereza ma valve ndi ochepa.

7. Nembanemba ya reverse osmosis yatsekedwa ndi zonyansa:
Kuphatikiza pa prepreatment ikhoza kutsekedwa, nembanemba ya reverse osmosis imathanso kutsekedwa.Madzi osaphika amakhala ndi zonyansa zambiri.Nthawi zambiri chipangizo chopangira mankhwala chimatha kusefa zonyansa zambiri kuti madzi omwe ali ndi mphamvu akwaniritse zofunikira za reverse osmosis.Komabe, machitidwe ena opangira mankhwala amapangidwa mopanda nzeru, zomwe zimapangitsa kuti zikhale zonyansa monga organic matter, chlorine yaulere, ndi zolimba zoyimitsidwa.Kulowa mkati mwa membrane element, kuchititsa kutsekeka kwa membrane element.Pamene zonyansa zimatsekereza kukula kwa pore nembanemba, sipadzakhala kupanga madzi.

8. Makina osefa atsekeredwa:
Pogwiritsa ntchito, njira zodzitetezera zoyenerera nthawi zambiri zimawonjezeredwa kuseri kwa nembanemba ya reverse osmosis kuteteza madzi amadzimadzi kuti asakhudzidwe ndi zinthu zina, monga kusefera kwa carbon activated, kusefera moyenera, ndi zina zotero. zimakhudzanso reverse osmosis ya kupanga madzi dongosolo.
