Iingxaki eziqhelekileyo ekusebenziseni i-industrial reverse osmosis membrane components

1.Ukuthomalalisa ukuqukuqela kwamanzi

Isizathu: I-Membrane fouling, i-organic matter, i-inorganic matter, i-solids emisiwe, i-microorganisms kunye nezinye izinto ezingcolileyo kumthombo wamanzi ziya kuqokelela ngokuthe ngcembe phezu komphezulu we-membrane, zenze i-membrane engcolileyo; Ingxaki yokukala, apho ubulukhuni be-ion emanzini busabelana nezinye ii-ion kumphezulu we-membrane ukuze zenze iidiphozithi; Ukuguga kweMembrane, njengoko ixesha lokusetyenziswa lisanda, izinto ze-membrane ziya kuba kwinqanaba elithile lokuguga; Iimeko zokusebenza ezingafanelekanga, ezifana noxinzelelo oluphezulu lwe-inlet, izinga lokungena eliphantsi kakhulu, okanye ukushisa okuphezulu kakhulu; Ukucoca okungaphelelanga kunokubangela ukukhutshwa okungaphelelanga kwezinto ezingcolileyo, okukhokelela ekuqokeleleni ukungcola kwi-membrane surface kwakhona.

Indlela yesigwebo: Ukubeka iliso rhoqo ukuveliswa kwamanzi kunye nomgangatho wenkqubo ye-osmosis ye-reverse, thelekisa ukuhanjiswa kwamanzi okuqala kunye nokukhoyo ngexesha lokusebenza; Xa ukubeka esweni utshintsho kuxinzelelo lwenkqubo kunye nokuthotywa kwe-flux flux kwenzeka, inkqubo inokufuna uxinzelelo oluphezulu lokugcina izinga lokuvelisa amanzi okuqala; Ukuncipha kokuhamba kwamanzi kwizinto ze-membrane ngokuqhelekileyo kuhamba kunye nokunciphisa izinga lokususwa kwetyuwa. Ukuba izinga lokususwa kwetyuwa lifunyenwe lingaphantsi kwexabiso loyilo ngexesha lokuvavanya, ingaba ngumqondiso wokuthotywa kwamanzi.

Amanyathelo okuphendula: Ukucoca rhoqo amacandelo e-membrane kwaye ukhethe ii-agent ezifanelekileyo zokucoca ukucoca umva ngokohlobo lokungcola; Qinisekisa ukuba iimeko zokusebenza zenkqubo ye-membrane ziphakathi koluhlu olucetyiswayo, ugweme ukunyanzeliswa kwe-inlet ngokugqithisileyo kunye nobushushu, kwaye uqinisekise izinga lokungena elizinzile; Ukwamkela iindlela eziphambili zonyango zangaphambili ezifana nentlenga, ukuhluzwa, ukuthambisa, kunye nokususwa kwentsimbi ukunciphisa umthwalo wongcoliseko emanzini; Ukuba umbane wamanzi we-membrane awuzange ubuyiselwe ngokufanelekileyo emva kwemijikelezo emininzi yokucoca kwaye kukho iimpawu zokuguga okanye umonakalo kwizinto eziphathekayo ze-membrane, ukutshintshwa kwento ye-membrane kunokuqwalaselwa.

2.Isenzeko sokwandisa

Isizathu: Ubulunga bamanzi abuzange buhlalutywe ngokupheleleyo, nto leyo eyakhokelela kuyilo lwenkqubo olungekho ngqiqweni; Ukusetyenziswa okungafanelekanga okanye ukungonelanga kwedosi ye-scale inhibitors; Umgangatho wamanzi utshintshile, kwaye iiparamitha zokusebenza kwenkqubo azizange zilungiswe ngexesha elifanelekileyo.

Isikhokelo sempendulo: Ukuqhuba uhlalutyo olubanzi lomgangatho wamanzi phambi koyilo lwesixokelelwano; Khetha ii-inhibitors zesikali ezisebenzayo/i-dispersants ukwenzela idosi; Ukulungelelanisa imilinganiselo yokusebenza kwenkqubo ngexesha elifanelekileyo xa umgangatho wamanzi utshintsha; Susa okanye unciphise ii-ion ezibangela ukukala ngexesha lonyango lwangaphambili.

3.I-oxidation phenomenon

Isizathu: I-chlorine eshiyekileyo ngokugqithisileyo okanye ezinye izinto ze-oxidizing kumanzi angenayo kwi-membrane system.

Isikhokelo sempendulo: Thatha amanyathelo afana nokongeza ii-agent zokunciphisa ukuqinisekisa ukuba i-chlorine eseleyo kwimpembelelo ingaphantsi kwe-0.1ppm; Faka izixhobo ze-ORP / i-chlorine eshiyekileyo kwinkqubo yokubeka iliso ngexesha langempela ukuqinisekisa ukuba izinto ze-oxidizing azifaki kwi-membrane element RO inkqubo.

4.Isenzeko seteleskopu

Isizathu: Ukungaphumeleli ukulandela iimfuno ngexesha lofakelo okanye ukuchithwa kubangele ukungahambi kakuhle phakathi kwe-osmosis membranes; Ukungonelanga kokuqina kunye namandla egobolondo le-membrane kubangele i-deformation ngexesha lokusebenza ngoxinzelelo; Xa uqala ipompo yoxinzelelo oluphezulu, uxinzelelo lwe-inlet lwenkqubo lukhuphuka ngokukhawuleza.

Isikhokelo sempendulo: Ukomeleza ukurekhodwa kunye nohlalutyo lwedatha yokusebenza. Emva kokulinganisa idatha, xa ukuhlukana koxinzelelo kudlula i-15% yexabiso lokuqala, ukucocwa kweekhemikhali kufuneka kwenziwe ngexesha elifanelekileyo, kwaye ingqalelo kufuneka ihlawulwe ukuba ingagqithisi umlinganiselo ophezulu ovumelekileyo woxinzelelo. Nje ukuba kwenzeke into enzulu yeteleskopu, kuyafuneka ukuba kuthathelwe indawo i-membrane ezonakalisiweyo kwaye kuphandwe unobangela wokumahluko woxinzelelo ongaphaya komgangatho.

5.I-concentration polarization phenomenon

Isizathu: Ngexesha lenkqubo ye-osmosis ebuyela umva, ngenxa yokuhamba kwamanzi ngokuqhubekayo kwi-membrane, kukho umahluko woxinaniso phakathi kwamanzi etyuwa kufuphi nomphezulu we-membrane kunye ne-inlet yetyuwa. Ukugxininiswa kwesisombululo kwi-membrane ebusweni buphezulu, kwaye njengoko ubuninzi bamanzi budlula kwi-membrane surface, ukugxininiswa kwanda kakhulu, ukwenza isisombululo esiphezulu. Ezinye iityuwa ziya kuthi chu ngokucotha iikristale.

Isikhokelo sempendulo: Ukwandisa izinga lokuhamba kwamanzi agxininisiweyo kunye nokwandisa amandla okucheba kwi-membrane surface; Lawula izinga lokubuyisela kunye ne-avareji ye-flux yenkqubo.

6.Isenzeko sokuqhawuka

Isizathu: Uxinzelelo oluphezulu lokungena, ubushushu obuphezulu, isando samanzi. Xa kukho umoya kwi- reverse osmosis system, impompo yoxinzelelo oluphezulu iyaqaliswa. Uxinzelelo lwempompo yoxinzelelo oluphezulu luphakama ngokukhawuleza, olunokubangela amandla anamandla kwi-membrane ye-RO, okubangela umphumo wesando samanzi kunye nomonakalo olula kwi-membrane ye-osmosis.

Isikhokelo sempendulo: Emva kokuba i-membrane element ixininiswe, i-membrane eyonakeleyo kufuneka ithathelwe indawo; Lawula uxinzelelo lokusebenza kunye nobushushu bento ye-membrane ngaphakathi kweemfuno zoyilo.

7.Umonakalo womphezulu weMembrane

Isizathu: I-particle kumanzi angenayo ingena kwinkqubo ye-RO, ibangela imikrwelo kwi-membrane surface; Imikrwelo ebangelwa zizinto zokukala; Ihamile yamanzi; Izinto zekhemikhali zinokubangela umonakalo kwi-membrane yomhlaba.

Isikhokelo sempendulo: Faka endaweni yesihluzo sokhuseleko ngexesha elifanelekileyo ukukhusela amasuntswana aqinileyo emanzini ukuba angangeni kwi-membrane element; Xa ucoca amacandelo e-membrane engcolileyo, isantya sokuqala sokuhamba kufuneka sincitshiswe ukukhusela umonakalo obangelwa ukugungxula okugqithisileyo; Ukuthintela isando samanzi, ukukhutshwa koxinzelelo oluphantsi kufuneka kuqhutywe ngaphambi kokuba kuqaliswe ipompo yoxinzelelo oluphezulu, kunye nokunyuka koxinzelelo lwempompo ephezulu akufanele kube ngokukhawuleza. Ukuguquguquka okuguquguqukayo, ukuqala okuthambileyo okanye ivalve yokuvula kancinane yombane kufuneka isetyenziswe ukuqalisa impompo yoxinzelelo oluphezulu; Ukuthintela iikhemikhali ezingahambelaniyo ukuba zingangeni kwi-membrane system.
