Ungayikhusela njani i-reverse osmosis membrane ngexesha lokusebenza kwenkqubo?
Ukulungiswa kwangaphambili kwenziwe; iinkcukacha zokusebenza ngexesha lokusebenza zibaluleke ngakumbi—umonakalo omninzi welwelwesi ubangelwa "ziimpazamo zabantu," ezinje ngokunyuka koxinzelelo ngequbuliso okanye amazinga aphezulu okubuyela kwimeko yesiqhelo. Khumbula la manqaku mane aphambili:
- Ukunyuka koxinzelelo olucothayo: Isantya kufuneka sibe ≤0.07 MPa/min. Xa uqalisa inkqubo, kuphephe ukuvula ivalvu ngequbuliso! Ukunyuka koxinzelelo ngokukhawuleza kunokubangela ukothuka kwizinto zemembrane, okukhokelela ekungalungelelaniseni kakuhle kwemicu yemembrane kunye nokuqhekeka kweglue yokutywina. Indlela echanekileyo kukuvula kancinci kancinci ivalvu yamanzi okuphakelwa, ukuvumela uxinzelelo ukuba lunyuke kancinci luye kwixabiso elimiselweyo.
- Izinga lokuBuyisa uLawulo: Kwimodyuli enye ≤15%, inkqubo ≤85%. Okukhona izinga lokubuyisela liphezulu, kokukhona izinga lokungcola liphezulu kwicala elixineneyo, nto leyo enyusa amathuba okukhula. Umzekelo, ukuba izinga lokubuyisela imodyuli enye lidlula i-15%, izinga letyuwa kwicala elixineneyo liya kuphinda kabini, lenze ngokukhawuleza isikali esivala iimbobo zemembrane. Lungisa izinga lokubuyisela inkqubo ngokusekelwe kumgangatho wamanzi; kumanzi anetyuwa eninzi, kucetyiswa ukuba uwanciphise ngokufanelekileyo.
- Ukucoca Kwangethuba: Ukuba kuvela imiqondiso emithathu yesilumkiso, lixesha lokucoca. I-membrane ayisiyo "ingenakulungiswa." Xa ungcoliseko lufikelele kwinqanaba elithile, ukucoca kuyimfuneko ukuze kuthintelwe umjikelo onzima.
Umthamo wamanzi emveliso wehla ngaphezulu kwe-10% ukusuka kwixabiso lokuqala
I-TDS yamanzi aveliswayo inyuke ngaphezulu kwe-15% xa kuthelekiswa nexabiso lokuqala
Umahluko woxinzelelo kwi-membrane uyanda ngaphezulu kwe-15% xa kuthelekiswa nexabiso lokuqala. Ukucoca kufuneka kwenziwe ngokulandelelana: ukucoca kokuqala kwe-alkaline (ukususa izinto eziphilayo kunye nee-colloids), kulandele ukucoca nge-asidi (ukususa isikali se-calcium-magnesium kunye ne-metal oxides). Sebenzisa ii-arhente zokucoca ezikhethekileyo kwaye uphephe ii-asidi ezinamandla okanye ii-alkali ukuthintela umonakalo oshiyekileyo kwi-membrane.
- Ukubeka esweni ngexesha langempela: Landelela ngokusondeleyo amanqaku amathathu edatha abalulekileyo—ukurekhoda kwemihla ngemihla koxinzelelo lwamanzi okutya, i-TDS yamanzi emveliso, kunye nesantya sokuhamba komxube. Ukuba kukho naziphi na izinto ezingaqhelekanga ezivelayo (njengokunyuka kwe-TDS ngequbuliso), phanda ngokukhawuleza unobangela ukuze uthintele iingxaki ezincinci ukuba zingabi ziingxaki ezinkulu.
