Ungayisebenzisa kanjani i-membrane entsha ye-RO reverse osmosis ngendlela efanele?

• Amaphuzu wezobuchwepheshe okusebenzisa i-membrane entsha ye-RO reverse osmosis:
  Okokuqala, hlambulula isihlabathi sequartz negobolondo likakhukhunathi ecushwe ikhabhoni, bese uhlanza isihlabathi sequartz esisanda kufakwa kanye negobolondo likakhukhunathi elicushwe ikhabhoni isikhathi eside.
  2. Hlola ukuthi ingabe ikhona yini i-chlorine eyinsalela, uma kukhona i-chlorine eyinsalela eyeqa izinga, xazulula inkinga ye-chlorine esele bese uqhubekela esinyathelweni esilandelayo se-RO reverse osmosis membrane.
  3. Ngemuva kokuthi ifilimu entsha ifakiwe, imanzise bese ucwilisa ifilimu amahora angu-1 ~ 2, ngoba ifilimu eyomile, ifilimu efakwe emanzini inomanzi ukuze ivimbele ifilimu ukuba ingalinyazwa ukucindezela okukhulu kakhulu.
  4. Bese uqala i-high-pressure pump, ukucindezela kufanele kukhuphuke kancane kancane, kusuka ku-2 kg kuya ku-8 ~ 10 kg, izinga lokukhipha usawoti we-membrane entsha lingcono.
  5. I-chlorine esele ilawulwa ngaphansi kuka-0.003.
  6. Vula i-valve yamanzi agxilile ngaphambi kokuqala iphampu yokucindezela okuphezulu, futhi ulungise kancane kancane i-valve yamanzi egxilile ngemva kokuvulwa kwepompo yokucindezela okuphezulu ukuze ulawule izinga lokubuyisela ulwelwesi olulodwa cishe ngo-15%.
  7. Amanzi akhiqizwa engxenyeni yokuqala yehora kufanele akhishwe, ngoba kukhona uketshezi oluvikelayo kulwelwesi ukuze kugwenywe ukuthinta ukunambitheka kwamanzi.
  8. Thola inani elingu-PH lamanzi anamandla, ngaphezu kuka-6.5.

• Ungahlulela kanjani ukuthi ulwelwesi olungemuva lwe-osmosis ludinga ukuhlanzwa?

Izakhi zolwelwesi lwe-osmosis ezibuyela emuva zingasetshenziswa cishe iminyaka emi-2 ~ 3. Uma ufuna ukunweba impilo yesevisi, ungakwazi ukuhlanza izakhi zolwelwesi lwe-osmosis, ezivame ukuhlukaniswa zibe izindlela ezimbili: ukushaywa komzimba kanye nokuguquguquka kwamakhemikhali. Izakhi zolwelwesi lwe-osmosis ezibuyela emuva zingasetshenziswa cishe iminyaka emi-2 ~ 3. Uma ufuna ukunweba impilo yesevisi, ungakwazi ukuhlanza izakhi zolwelwesi lwe-osmosis, ezivame ukuhlukaniswa zibe izindlela ezimbili: ukushaywa komzimba kanye nokuguquguquka kwamakhemikhali.

Ukuhlanza ama-membrane e-osmosis angemuva

Njengomthetho wesithupha, uma iyunithi ye-osmosis ehlane ihlanzwa njalo ezinyangeni ezintathu noma ngaphezulu. Uma ihlanzwa kanye njalo ezinyangeni ezingu-1-3, kuyadingeka ukuthuthukisa izimo zokusebenza nokuthuthukisa umphumela wokwelapha.

Yahlulela isimo sokuhlanza:

(1) Ukukhiqizwa kwamanzi ahlanzekile ajwayelekile kwehle ngaphezu kwe-10%.

(2) Izinga elijwayelekile lokungena kukasawoti likhuphuke ngaphezu kwe-10%.

(3) Ukuze kugcinwe izinga elijwayelekile lokugeleza kwamanzi ahlanzekile, umehluko wengcindezi phakathi kwamanzi okuphakelayo namanzi agxilile ukhuphuka ngaphezu kuka-10% ngemva kokulinganisa izinga lokushisa.

(4) Umshini wangaphakathi unezinto ezingcolisayo nezikali ezinkulu.

(5) Ngaphambi kokuthi idivayisi ye-RO ingasebenzi isikhathi eside.

(6) Ukunakekelwa okujwayelekile kwempahla ye-RO.

Okungcolisayo

Ukungcola okuvamile ku-reverse osmosis membrane elements ikakhulukazi i-CaCO3, i-CaSO4, i-BaSO4, i-SrSO4, ama-oxide ensimbi, amadiphozithi e-silicon, izinto eziphilayo kanye ne-biological slime. Uma uhlelo lokudosa lwe-scale inhibitor noma uhlelo lokwengeza i-asidi luhluleka, i-CaCO3 ingase ifakwe ku-elementi ye-membrane, futhi ukuhlanza amakhemikhali kufanele kusetshenziselwe ukuhlanza umjikelezo noma ukucwiliswa ebusuku.

Ukwakhiwa

Ukungcola okuhlukene kubangela amazinga ahlukene omonakalo kulwelwesi, futhi ukungcola okuhlukahlukene kusebenzisa izixazululo ezihlukene zokuhlanza.

Imishini yokuhlanza

Ngokuvamile yakhiwa iphampu yokuhlanza, ibhokisi lokulungiselela amakhemikhali, isihlungi sokuphepha esingu-5-20um, i-heater, ama-valve amapayipi ahlobene nezinsimbi zokulawula.

Izindlela zokuhlanza zihlanganisa ukucwiliswa kwe-static kanye nokuhlanza i-cyclic. Ukucwiliswa okungaguquki kucwiliswe oketshezini lokuhlanza, futhi isikhathi sicishe sibe ngu-1-15h kuye ngezinga lokungcola. Izinyathelo ezijwayelekile zokuhlanza i-cyclic yilezi:

1. Pompa amanzi ahlanzekile ebhokisini lokulungiselela ungene emkhunjini wokucindezela bese uwukhipha imizuzu embalwa.

2. Lungiselela isixazululo sokuhlanza ngamanzi ahlanzekile ebhokisini lokulungiselela.

3. Zungezisa umkhumbi wokucindezela ngoketshezi lokuhlanza ihora elingu-1 noma ufinyelele isikhathi esinqunyiwe. Izinga lokugeleza kokuhlanza linganqunywa ngokusho kwethebula elingezansi, futhi lapho ukungcola kunzima, ukugeleza kokuhlanza kunganyuswa ku-150% we-resin etafuleni. Ngalesi sikhathi, ukwehla kwengcindezi yokuhlanza kukhulu, futhi ukulawula okuvamile akukho ngaphezu kuka-(0.10-0.14MPa)/into yefilimu yezimpande noma umhlangano wefilimu ongu-0.4MPa/impande. Ekuqaleni kokuhlanzwa komuthi, i-50% yenani lokugeleza kumitha ingasetshenziswa ukuthululela isisombululo sokuhlanza esishisayo emkhunjini wokucindezela ukulawula ukucindezela, ukuze ukwazi ukunqoba ukwehla kokucindezela phakathi kokungena nokuphuma kwamanzi ngaphandle kwamanzi ahlanzekile aphumayo. Ukuze ugweme ukuhlanjululwa kwesisombululo sokuhlanza, i-valve yokukhipha amanzi egxilile ingavulwa ukukhipha amanzi aqoqiwe ohlelweni ngaphambi kokuhlanza. Isistimu ye-osmosis ephambene ingahlanzwa ngezigaba. Indlela yokuhlanza iyafana nendlela yokugijima, futhi ukuhlanzwa okuhlanekezelwe akuvunyelwe, ngaphandle kwalokho kungabangela umqulu wefilimu ukuthi uqhume futhi kulimaze izakhi zefilimu.

4. Ngemva kokuqedwa kokuhlanza umjikelezo, geza ibhokisi lokulungiselela ngamanzi ahlanzekile.

5. Hlanza isitsha sokucindezela ngamanzi amasha.

6. Ngemva kokuwasha, sebenzisa i-reverse osmosis system nevalvu yokukhipha amanzi ahlanzekile ivuliwe kuze kube yilapho amanzi ahlanzekile ehlanzekile, engenagwebu, noma engenawo uketshezi lokuhlanza, ngokuvamile oluthatha imizuzu eyi-15-30.

Hlehlisa ukushintshwa kolwelwesi lwe-osmosis

Ngemva kokusebenza okuvamile kwempahla ye-osmosis ehlehlayo isikhathi esithile, izakhi zolwelwesi lwe-osmosis ezibuyela emuva zizongcoliswa izinto eziqinile ezimisiwe noma usawoti ongancibiliki okungenzeka ube khona emanzini okuphakelayo, futhi kuzovela izimpawu ezilandelayo:

1. Isisindo sezakhi ze-membrane zemishini ye-osmosis engemuva senyukile;
2. Izinga lokususwa kwe-membrane ye-RO landa noma lehla kakhulu;
3. Ngaphansi kwengcindezi evamile, ukukhiqizwa kwamanzi kwemishini ye-osmosis ehlehlayo yehle kakhulu.
4. Ukuze kuzuzwe isivuno samanzi esijwayelekile, ingcindezi yokusebenza idinga ukuthuthukiswa;
5. Ukwehla kwengcindezi phakathi kwamanzi anamandla kanye namanzi agxilile emishini ye-osmosis ehlehlayo kuyanda;
6. Thatha i-membrane element emkhunjini wokucindezela, uthele amanzi ohlangothini lokungena lwe-membrane element eqondile, uma amanzi engakwazi ukugeleza ku-membrane element, echichima kuphela ebusweni bokuphela, okubonisa ukuthi umzila wokugeleza we-inlet uvinjelwe.
