Ubusazi? Ukukhusela iiMembranes zakho ze-RO Ngexesha lokuCima kubalulekile!

Xa iinkqubo ze-osmosis (RO) zicoca ngenkuthalo amanzi, sibeka iliso ngononophelo uxinzelelo, ukuhamba kunye nomgangatho. Kodwa kwenzeka ntoni xa isixhobo siyeka? Okothusayo kukuba, eli xesha lingasebenziyo libeka iingozi ezibalulekileyo ezifihlakeleyo kwiinwebu ezithambileyo ze-RO, ezinokuthi zibangele umonakalo ongalungisekiyo kunye nokunciphisa ubomi bazo. Ukuqonda le mingcipheko kunye nokuphumeza iinkqubo ezifanelekileyo zokuvala ukuvalwa kubalulekile.

Ukuvalwa Kwenzeke Njani IiMembranes ze-RO:

Ukukhula kwebhayoloji (i-Biofouling): Amanzi amileyo ngaphakathi kwimikhumbi yoxinzelelo aba yindawo yokuzalela iintsholongwane ezifana nebhaktiriya kunye nomngundo. Ezi zinto ziphilayo ziphindaphindeka ngokukhawuleza, zenze iifilimu zebhayoloji ezincangathi ngokuthe ngqo kumphezulu wenwebu. Le biofilm inciphisa kakhulu i-flux (ukukhutshwa kwamanzi) kunye nokwandisa ityuwa, intsebenzo ephantsi ngokusisigxina nasemva kokucoca.

Ukubunjwa kweScale: Iiminerali ezinyibilikileyo ezifana ne-calcium carbonate, i-sulfates, okanye i-silica, egxininiswe kumphezulu we-membrane ngexesha lokusebenza, inokukhanya kwaye ibe lukhuni kwi-membrane ngexesha lokuvalwa. Oku kulinganiswa kwehlisa kakhulu imveliso kwaye kuhlala kunzima ukukususa ngokupheleleyo.

Ukuphelelwa ngamanzi kunye ne "Creep": Iimembranes zenzelwe ukusebenza phantsi koxinzelelo. Ngexesha lokuvalwa okwandisiweyo ngaphandle kokumanzisa, umaleko ongeneka lula unokoma. Okubi kakhulu, ngaphandle koxinzelelo lwangaphakathi lokubamba imilo yazo, izinto ezixineneyo zenwebu ezipakishwe ngaphakathi kweenqanawa zoxinzelelo zinokukhubaza ngokwasemzimbeni ("ukukhasa"). Le deformation yonakalisa imijelo yokuhambahamba entsonkothileyo kunye nesakhiwo sezinto eziphathekayo, okukhokelela kwilahleko yokusebenza esisigxina kunye nokuvuza okunokwenzeka.

Ukuthotywa kweMichiza (Okunokwenzeka): Ukuba iikhemikhali ezigcinayo ezingahambelaniyo zithomalalisa ngokuhamba kwexesha okanye zigungxulwa ngokungafanelekanga ngaphambi kokuba ziqalise kwakhona, zinokuhlasela i-membrane yepolymer ngokwayo. Ukungcola okungena kwinkqubo engavalwa kakuhle ngexesha lokuphumla nako kunokubeka umngcipheko weekhemikhali.

Izisombululo: Ukukhusela iiMembranes Ngexesha lokuValwa

Isitshixo lugcino olusebenzayo, olulungiselelwe ixesha lokuvala:

Ukuvalwa kwexesha elifutshane (

Ukugungxula: Yenza ukugungxulwa okucokisekileyo, okuphantsi koxinzelelo ngamanzi emveliso ye-RO (okanye i-permeate ecocekileyo) ukushenxisa amanzi okutya axinanisiweyo ukusuka kumphezulu wenwebu ngoko nangoko emva kokumisa ukuhamba kokutya.

Gcina ubumanzi: Gcina izinto ze-membrane zifakwe ngokupheleleyo kwaye inkqubo itywinwe ukukhusela ukuphelelwa ngamanzi emzimbeni. Jikelezisa kwakhona okanye ugungxule rhoqo iiyure ezingama-24-48 ukuba kunokwenzeka.

Ukuvalwa kwexesha elide (> Iiyure ezingama-72) okanye uGcino:

Ukucoca ngokucokisekileyo: Yenza umjikelo opheleleyo wokucoca ngaphambi kokuvalwa ukususa iifoulants kunye nezandulela zesikali.

Isisombululo sokuGcinwa: Gubha yonke inkqubo, kubandakanywa iinqanawa zoxinzelelo kunye nezinto, kunye nesisombululo esifanelekileyo sokulondoloza:

I-Sodium Bisulfite (I-Common & Preferred): Isisombululo se-1% sisetyenziswa ngokubanzi ukulawula ukukhula kwe-microbial ngokusebenzisa i-oxygen scavenging. Ifuna uvavanyo lwamaxesha athile kunye nokuzaliswa/ukutshintshwa.

IGlycerin yeBanga lokuTya: Ihlala isetyenziselwa ukugcinwa okomileyo. Iimembranes kufuneka zizaliswe nge-15-20% yesisombululo se-glycerin kwaye ivumeleke ukuba ikhuphe ngokucokisekileyo ngaphambi kokutywinwa kokugcinwa kwexesha elide ukukhusela zombini ukukhula kwe-microbial kunye nokuphelelwa amandla kwamanzi. Qaphela: Abanye abathengisi bacebisa kakhulu ngokuchasene nokugcinwa okomileyo ngenxa yengozi yokunyuka.

Ugxininiso oluchanekileyo: Landela izikhokelo zomenzi zoxinaniso oluchanekileyo lwesilondolozi esikhethiweyo.

Iqondo lobushushu: Gcina ngaphantsi kwe-35°C (95°F) kodwa ngaphezu komkhenkce. Ugcino olubandayo (°C okanye 50°F) iphinde icothise ukukhula kweentsholongwane.

Isitywina kwaye ukhusele: Qinisekisa ukuba zonke izivulo zitywinwe ngokuqinileyo ukunqanda ukuphuma komphunga kunye nongcoliseko.

Ukubeka iliso rhoqo: Jonga rhoqo i-pH kunye nokugxininiswa kwesisombululo sokugcina, ukubuyisela yonke imihla ye-30-90 ukuba kuyimfuneko.

Gwema i-Backpressure: Soloko ukhulula uxinzelelo kwicala lokugxila ngaphambi kokucima ipompo yoxinzelelo oluphezulu ukukhusela i-deformation.

Okubalulekileyo emva kokuvala:

Gubha Ngokucokisekileyo: Phambi kokuba uqalise kwakhona, gubha inkqubo kakhulu ngamanzi emveliso okanye ngamanzi esondlo anoxinzelelo oluphantsi ukususa zonke iikhemikhali zolondolozo.

Ukuqalisa kancinci: Phinda ucinezele inkqubo kancinane ngokweenkcazo zomenzi.

Ukubeka iliso kwiNtsebenzo: Nika ingqalelo ngokukhawuleza ukuhamba kwe-permeate eqhelekileyo, ukuhla koxinzelelo, kunye nokwaliwa kwetyuwa kwiiyure / iintsuku emva kokuqalisa kwakhona.

Isiphelo:

Ungavumeli ixesha lokuphumla lonakalise utyalo-mali lwakho! Ukucima nje inkqubo ye-RO ngaphandle kwamanyathelo okugcina afanelekileyo kumema i-biofouling, ukukala, kunye ne-membrane deformation. - ababulali abathuleyo abathoba intsebenzo kwaye babangele ukusilela kwangaphambi kwexesha. Ngokuqonda le mingcipheko kunye nokuphumeza ngenkuthalo iinkqubo ezifanelekileyo zokugungxulwa okanye zokugcina ngokusekwe kwixesha lokuvalwa kunye neengcebiso zomenzi, uyaqinisekisa ukuba ii-membrane zakho zihlala zikhuselekile, zisebenza ngokugqibeleleyo kubomi bazo boyilo obupheleleyo, kwaye zihambisa amanzi acocekileyo othembele kuwo. Khumbula, umzamo omncinci ngexesha lokuvalwa konga iindleko ezibalulekileyo kunye nexesha lokuphumla kamva.
