Uthi bewazi? Ukuvikela AmaMembranes Akho E-RO Ngesikhathi Sokuvalwa Kubalulekile!

Lapho amasistimu e-Reverse Osmosis (RO) ehlanza amanzi ngenkuthalo, siqapha ngokucophelela ingcindezi, ukugeleza, kanye nekhwalithi. Kodwa kwenzekani lapho imishini ima? Ngokumangazayo, lesi sikhathi sokungenzi lutho sibeka izingozi ezibalulekile ezifihlekile kulwelwesi oluthambile lwe-RO, olungase lubangele umonakalo ongalungiseki futhi lufinyeze ubude bazo bokuphila. Ukuqonda lezi zingozi nokusebenzisa izinqubo zokuvala shaqa kubalulekile.

Ukuvala Shaqa Kulimaza Kanjani AmaMembrane E-RO:

Ukukhula Kwebhayoloji (I-Biofouling): Amanzi amile ngaphakathi kwemikhumbi yokucindezela aba indawo yokuzalanisa amagciwane afana namagciwane kanye nesikhunta. Lezi zinambuzane ziphindaphindeka ngokushesha, zenze ama-biofilm anamathelayo ngqo endaweni engaphezulu ye-membrane. Le biofilm inciphisa kakhulu i-flux (ukukhishwa kwamanzi) futhi ikhuphule i-salt passage, ihlambalaza ukusebenza unomphela ngisho nangemva kokuhlanza.

Ukwakheka Kwesikali: Amaminerali ancibilikisiwe njenge-calcium carbonate, ama-sulfate, noma i-silica, agxile kulwelwesi lwangaphakathi ngesikhathi sokusebenza, angacwebezela futhi abe lukhuni kulwelwesi ngesikhathi sokuvalwa. Lokhu kukala kwehlisa kakhulu ukukhiqiza futhi kuvame ukuba nzima ukukususa ngokuphelele.

Ukuphelelwa amanzi emzimbeni kanye ne-"Creep": Amamembrane aklanyelwe ukusebenza ngaphansi kwengcindezi. Ngesikhathi sokuvala okunwetshiwe ngaphandle kokumanzisa, izendlalelo ezivunyeleka kancane zingama kancane. Okubi nakakhulu, ngaphandle kwengcindezi yangaphakathi yokubamba isimo sazo, izakhi zolwelwesi oluminyene ezipakishwe ngaphakathi kwemikhumbi yokucindezela zingakhubazeka ngokomzimba ("zikhasa"). Lokhu kuguqulwa kulimaza imigudu yokugeleza eyinkimbinkimbi kanye nesakhiwo sezinto ezibonakalayo, okuholela ekulahlekeni kokusebenza unomphela kanye nokuvuza okungenzeka.

Ukuwohloka Kwamakhemikhali (Okungenzeka): Uma amakhemikhali alondolozayo angahambelani ewohloka ngokuhamba kwesikhathi noma ashaywe ngendlela engafanele ngaphambi kokuqala kabusha, angahlasela i-membrane polymer ngokwayo. Ukungcola okungena ohlelweni oluvalwe kahle ngesikhathi sokuphumula kungase kube yingozi yamakhemikhali.

Izixazululo: Ukuvikela AmaMembrane Ngesikhathi Ukuvala

Ukhiye uwukulondoloza okusebenzayo, okuhambisana nesikhathi sokuvala:

Ukuvalwa Kwesikhathi Esifushane (

I-Flush: Yenza i-flush eqinile, enengcindezi ephansi ngamanzi omkhiqizo we-RO (noma i-permeate ehlanzekile) ukuze ukhiphe amanzi okuphakelayo agxile kulwelwesi ngokushesha ngemva kokumisa ukugeleza kokuphakelayo.

Gcina Ubumanzi: Gcina izakhi ze-membrane zicwile ngokuphelele futhi isistimu ivalwe ukuvimbela ukuphelelwa amanzi emzimbeni. Zungezisa kabusha noma ushaye phansi njalo emahoreni angama-24-48 uma kungenzeka.

Ukuvalwa Kwesikhathi Eside (>Amahora angu-72) noma Isitoreji:

Ukuhlanza Okuphelele: Yenza umjikelezo wokuhlanza ophelele ngaphambi kokuvalwa ukuze ususe ama-foulants kanye nezandulela zesikali.

Isixazululo Sokulondolozwa: Hlanza lonke uhlelo, okuhlanganisa imikhumbi yokucindezela nezinto, ngesisombululo esifanele sokulondoloza:

I-Sodium Bisulfite (Ejwayelekile & Ekhethwayo): Isixazululo esingu-1% sisetshenziswa kabanzi ukulawula ukukhula kwamagciwane ngokukhipha umoya-mpilo. Idinga ukuhlolwa ngezikhathi ezithile nokugcwaliswa/ukushintsha.

IGlycerin Yebanga Lokudla: Ivamise ukusetshenziselwa isitoreji esomile. Amangqamuzana kufanele agcwaliswe ngesisombululo se-glycerin esingu-15-20% futhi avunyelwe ukuba aphume kahle ngaphambi kokuvalelwa ukuze agcinwe isikhathi eside ukuvimbela kokubili ukukhula kwamagciwane kanye nokuphelelwa amanzi emzimbeni. Qaphela: Abanye abathengisi bayeluleka ngokuqinile ngokumelene nesitoreji esomile ngenxa yezingozi ezinyakazayo.

Ukugxila Okunembile: Landela imihlahlandlela yomkhiqizi mayelana nokugxiliswa okunembile kwesilondolozi esikhethiwe.

Izinga lokushisa: Gcina ngaphansi kwama-35°C (95°F) kodwa ngaphezu kokubanda. Isitoreji esibandayo (°C noma 50°F) iphinde ibambezele ukukhula kwamagciwane.

Seal & Vikela: Qinisekisa ukuthi zonke izimbobo zivalwe ngokuqinile ukuze kuvinjelwe ukuhwamuka kwesixazululo nokungcola.

Ukuqapha Okuvamile: Hlola i-pH ngezikhathi ezithile kanye nokugxila kwesisombululo sesitoreji, ubeke esikhundleni saso njalo ezinsukwini ezingama-30-90 uma kudingeka.

Gwema I-Backpressure: Hlala njalo ukhulule ingcindezi ohlangothini lokugxilisa ingqondo ngaphambi kokuvala iphampu yokucindezela okuphezulu ukuze uvimbele ukuwohloka.

Okubalulekile Ngemuva kokuvala:

Hlanza Kahle: Ngaphambi kokuqalisa kabusha, shayela isistimu kakhulu ngamanzi omkhiqizo noma ngamanzi okuphakelayo anomfutho ophansi ukuze ususe wonke amakhemikhali okugcina.

Ukuqalisa Kancane Kancane: Phinda ucindezele isistimu kancane kancane ngokuya ngemininingwane yomkhiqizi.

Qapha Ukusebenza: Naka kakhulu ukugeleza kwe-permeate okujwayelekile, ukwehla kwengcindezi, nokwenqatshwa kukasawoti emahoreni/izinsuku ngemuva kokuqala kabusha.

Isiphetho:

Ungavumeli isikhathi sokuphumula sicekele phansi utshalomali lwakho! Ukumane uvale isistimu ye-RO ngaphandle kwezinyathelo ezifanele zokulondoloza kumema i-biofouling, ukukala, nokuguqulwa kwe-membrane. - ababulali abathule abalulaza ukusebenza futhi babangele ukwehluleka ngaphambi kwesikhathi. Ngokuqonda lezi zingozi nokusebenzisa ngenkuthalo izinqubo ezifanele zokugudluza noma zokulondoloza ezisekelwe esikhathini sokuvala shaqa kanye nezincomo zomkhiqizi, uqinisekisa ukuthi ulwelwesi lwakho luhlala luvikelekile, lusebenza ngokugcwele impilo yalo egcwele yokuklama, futhi iletha amanzi ahlanzekile othembele kuwo. Khumbula, umzamo omncane phakathi nokuvalwa konga izindleko ezinkulu kanye nesikhathi sokuphumula kamuva.
