Uyisebenzisa njani inwebu entsha ye-RO reverse osmosis ngokuchanekileyo?
- Amanqaku obugcisa bokusebenzisa i-RO entsha ye-osmosis membrane:
Okokuqala, hlambulula isanti yequartz kunye neqokobhe lekhokhonathi esebenzayo, kwaye uhlambe isanti esanda kufakwa yequartz kunye neqokobhe lekhokhonathi esebenzayo ixesha elide.
2. Khangela ukuba kukho i-chlorine eshiyekileyo, ukuba kukho i-chlorine eshiyekileyo edlula umgangatho, lungisa ingxaki ye-chlorine eshiyekileyo uze uqhubekele kwinqanaba elilandelayo le-RO reverse osmosis membrane.
3. Emva kokuba ifilimu entsha ifakwe, amanzi kwaye udibanise ifilimu kwiiyure ze-1 ~ 2, ngenxa yokuba ifilimu eyomileyo, ifilimu edibeneyo ifumile kakhulu ukukhusela ifilimu ukuba yonakaliswe ngoxinzelelo oluphezulu.
4. Emva koko qalisa ipompo yoxinzelelo oluphezulu, uxinzelelo kufuneka lunyuswe ngokukhawuleza, ukusuka kwi-2 kg ukuya kwi-8 ~ 10 kg, isantya se-desalination ye-membrane entsha ingcono.
5. I-chlorine eshiyekileyo ilawulwa ngaphantsi kwe-0.003.
6. Vula i-valve yamanzi egxininisiweyo ngaphambi kokuba uqalise ipompo yoxinzelelo oluphezulu, kwaye ulungise ngokukhawuleza i-valve yamanzi egxininisekile emva kokuba i-high-pressure pump ivuliwe ukulawula izinga lokubuyisela kwi-membrane enye malunga ne-15%.
7. Amanzi avelisiweyo kwisiqingatha sokuqala seyure kufuneka ahlanjululwe, kuba kukho ulwelo olukhuselayo kwi-membrane ukuphepha ukuchaphazela ukunambitha kwamanzi.
8. Khangela ixabiso le-PH lamanzi anempembelelo, ngaphezu kwe-6.5.
- Indlela yokugweba ukuba i-membrane ye-osmosis ifuna ukucocwa?
Izinto ezibuyela umva i-osmosis inwebu zinokusetyenziswa ngokubanzi malunga ne-2 ~ 3 iminyaka. Ukuba ufuna ukwandisa ubomi benkonzo, unokucoca i-reverse osmosis membrane elements, ezidla ngokuhlulwa zibe ziindlela ezimbini: ukugungxulwa komzimba kunye nokugungxulwa kweekhemikhali. Izinto ezibuyela umva i-osmosis inwebu zinokusetyenziswa ngokubanzi malunga ne-2 ~ 3 iminyaka.

Ukucocwa kwe-reverse osmosis membranes
Njengomthetho wesithupha, ukuba iyunithi ye-osmosis icoca rhoqo kwiinyanga ezintathu nangaphezulu. Ukuba ihlanjululwe kanye kwiinyanga ezi-1-3, kuyimfuneko ukuphucula iimeko zokusebenza kunye nokuphucula umphumo wonyango.
Gxininisa imeko yokucoca:
(1) Ukuveliswa komgangatho wamanzi acocekileyo kwehle ngaphezu kwe-10%.
(2) Izinga eliqhelekileyo lokungena kwetyuwa liye landa ngaphezu kwe-10%.
(3) Ukuze kugcinwe umlinganiselo oqhelekileyo wokuhamba kwamanzi ahlambulukileyo, umahluko woxinzelelo phakathi kwamanzi okutya kunye namanzi agxininisekile anyuswe ngaphezu kwe-10% emva kokulinganisa ubushushu.
(4) Isixhobo sangaphakathi sinongcoliseko olukhulu kunye nesikali.
(5) Ngaphambi kokuba isixhobo se-RO singasebenzi ixesha elide.
(6) Ukugcinwa rhoqo kwezixhobo zeRO.
Ungcoliseko
Ungcoliseko oluqhelekileyo kwireverse osmosis membrane elements are mainly CaCO3, CaSO4, BaSO4, SrSO4, metal oxides, silicon deposits, organic matter and biological slime. Xa inkqubo yedosing ye-scale inhibitor okanye inkqubo yokongeza i-asidi ingaphumeleli, i-CaCO3 inokufakwa kwizinto ze-membrane, kwaye ukucocwa kweekhemikhali kufuneka kusetyenziswe ukucoca i-cyclic okanye ukucwina ebusuku.
Ukuqulunqwa
Ukungcola okuhlukeneyo kubangela amanqanaba ahlukeneyo omonakalo kwi-membrane, kwaye ukungcola okuhlukeneyo kusebenzisa izisombululo ezahlukeneyo zokucoca.
Izixhobo zokucoca
Ngokuqhelekileyo iqulethwe yimpompo yokucoca, ibhokisi yokulungiselela iikhemikhali, i-5-20um yokukhusela i-filter, i-heater, i-valve yepayipi ehambelanayo kunye nezixhobo zokulawula.
Iindlela zokucoca ziquka ukuthambisa okumileyo kunye nokucoca ngebhayisekile. I-Static soaking ifakwe kulwelo lokucoca, kwaye ixesha limalunga ne-1-15h ngokuxhomekeke kwiqondo longcoliseko. Amanyathelo jikelele okucoca ngomjikelo ngala:
- Pump amanzi ahlambulukileyo kwibhokisi yokulungiselela kwisitya soxinzelelo kwaye uyikhuphe imizuzu embalwa.
- Lungiselela isisombululo sokucoca ngamanzi ahlambulukileyo kwibhokisi yokulungiselela.
- Biyela isitya soxinzelelo ngolwelo lokucoca ngeyure eli-1 okanye ufikelele kwixesha elimiselweyo. Isantya sokuhamba sokucoca sinokumiselwa ngokwetheyibhile engezantsi, kwaye xa ukungcoliswa kubi kakhulu, ukuhamba kokucoca kunokunyuswa ukuya kwi-150% ye-resin etafileni. Ngeli xesha, ukuhla kwengcinezelo yokucoca kukhulu, kwaye ulawulo oluqhelekileyo alukho ngaphezu kwe (0.10-0.14MPa) / i-root film element okanye i-0.4MPa / i-root film assembly. Ekuqaleni kokucocwa iyeza, i-50% yexabiso lokuhamba kwimitha ingasetyenziselwa ukuthulula isisombululo sokucoca esishushu kwisitya soxinzelelo ukulawula uxinzelelo, ukwenzela ukuba ikwazi ukunqoba ukuhla koxinzelelo phakathi kokungena kunye nokuphuma kwamanzi ngaphandle kwamanzi ahlambulukileyo aphuma ngaphandle. Ukuze ugweme ukuhlanjululwa kwesisombululo sokucoca, i-valve yokukhutshwa kwamanzi egxininisiweyo ingavulwa ukukhupha amanzi aqokelelweyo kwinkqubo ngaphambi kokucoca. Inkqubo ye-osmosis engasemva inokucocwa ngokwamacandelo. Isalathiso sokucoca siyafana nendlela yokuqhuba, kwaye ukucocwa komva akuvumelekanga, ngaphandle koko kunokubangela ukuba ifilimu iqhube kwaye yonakalise izinto zefilimu.
- Emva kokuba ukucoca umjikelezo kugqityiwe, hlamba ibhokisi yokulungiselela ngamanzi ahlambulukileyo.
- Hlanza isitya soxinzelelo ngamanzi amatsha.
- Emva kokugungxulwa, sebenzisa inkqubo ye-osmosis ebuyela umva ngevalve yokukhupha amanzi evulekileyo de amanzi amatsha acoceke, angabinagwebu, okanye angabinalwelo lokucoca, oludla ngokuthatha imizuzu eyi-15-30.
Reverse osmosis inwebu yokutshintshwa
Emva kokusebenza okuqhelekileyo kwesixhobo se-osmosis esibuyela umva kangangexesha elithile, izinto ezibuyela umva i-osmosis inwebu ziya kungcoliswa ziziqina ezimisiweyo okanye iityuwa ezinganyibilikiyo ezinokubakho kumanzi okutya, kwaye ezi mpawu zilandelayo ziya kuvela:
- Ubunzima bezinto ze-membrane ze-reverse osmosis izixhobo zandile;
- Izinga lokususwa kwe-membrane ye-RO landa okanye lehla kakhulu;
- Phantsi koxinzelelo olusemgangathweni, ukuveliswa kwamanzi kwezixhobo ze-osmosis ezibuyela umva kwehle kakhulu.
- Ukuze kuphunyezwe isivuno esisemgangathweni samanzi, uxinzelelo lokusebenza kufuneka luphuculwe;
- Ukuhla koxinzelelo phakathi kwamanzi anempembelelo kunye namanzi agxininisiweyo ezixhobo ze-osmosis eziguqukayo ziyanda;
- Thatha i-membrane element kwisitya soxinzelelo, ugalele amanzi kwicala lokungena le-membrane ethe tye, ukuba amanzi akakwazi ukuhamba nge-membrane element, aphuphuma kuphela ukusuka ekupheleni kobuso, ebonisa ukuba i-inlet flow channel ivaliwe.
