Abantu abaningi banokungaqondi kahle okumbalwa mayelana ne-membrane, ngakho-ke sinikeza izincazelo zale mibono eyiphutha evamile, ake sihlole ukuthi unayo yini!

Ukungaqondi kahle 1: Kunzima ukusebenzisa uhlelo lokuhlanza amanzi e-membrane

Isidingo sokulawula okuzenzakalelayo sohlelo lokwelashwa kwamanzi ulwelwesi siphezulu kakhulu kunesohlelo oluvamile lokwelapha amakhemikhali ezinto eziphilayo. Abasebenzisi abaningi bakholelwa ngephutha ukuthi uhlelo lokwelapha ulwelwesi lwamanzi lunzima ukusebenza.

Eqinisweni, ukusebenza kwesistimu yokwelapha ulwelwesi lwamanzi kuzenzakalela kakhulu, futhi ukusebenza kokuqala nokumisa, umthamo nokugeza nge-inthanethi konke kwenziwa ngokulawulwa kohlelo lwe-PLC. Inganganakwa, ukuhlolwa okuvamile okujwayelekile kuphela kanye nokukhipha, ukugcinwa nokuhlanza ngezikhathi ezithile kuyadingeka, futhi ngokuyisisekelo abekho abasebenzi abengeziwe abadingekayo.

Ukuhlanzwa okujwayelekile kanye nokugcinwa kwe-membrane kungenziwa kahle ngosuku olulodwa lokuqeqeshwa, okunzima kakhulu kunohlelo lwe-biochemical oludinga amakhono aphezulu aphelele ezisebenzi.

Ukungaqondi kahle 2: Ukutshalwa kwezimali okuphezulu, awukwazi ukukukhokhela

Abanye abantu bacabanga ukuthi utshalomali lwesikhathi esisodwa kanye nezindleko zokushintsha ulwelwesi ziphezulu kakhulu, ngakho abakwazi ukukukhokhela. Eqinisweni, ngokuthuthuka okusheshayo kwabahlinzeki be-membrane yasekhaya, intengo ye-membrane ihlale yehla.

Ukusebenzisa uhlelo lwe-MBR ulwelwesi kungasindisa izindleko zokwakha kanye nomhlaba, kunciphise inani lezindleko zokulahla udaka kanye nokulahla udaka, kubiza izindleko futhi kuyisinqumo esihle. Ngolwelwesi lwe-UF nohlelo lwe-RO, izinzuzo zezomnotho ezikhiqizwa ukugcwaliseka kokugaywa kabusha kwamanzi angcolile ziningi kakhulu kunokutshalwa kwezimali kumishini.

Ukungaqondi kahle 3: I-Membrane ithambile futhi kulula ukuphuka

Ngenxa yokuntula ulwazi, amasistimu olwelwesi olunwetshiwe aklanywa futhi akhiwa izinkampani ezithile zobunjiniyela anezinkinga zokuqhekeka kwefayibha kanye nokuchithwa kwemojula njll., futhi abasebenzisi bakholelwa ngephutha ukuthi imikhiqizo yolwelwesi kunzima ukuyinakekela. Eqinisweni, inkinga ikakhulukazi isuka ekwakhiweni kwenqubo kanye nesipiliyoni sokusebenza kwesistimu ye-membrane.

Ngomklamo ophusile wokwelashwa wangaphambi kokwelashwa kanye nedizayini yokuvikela ukuphepha, ulwelwesi lwe-PVDF oluqinisiwe lwekhwalithi ephezulu lungasetshenziswa isilinganiso esingaphezu kweminyaka engu-5, uma lusetshenziswa luhlanganiswe ne-RO membrane, impilo yesevisi ye-RO membrane inganwetshwa ngempumelelo.

Ukungaqondi kahle 4: Ibhrendi/inani lolwelwesi lubaluleke kakhulu kunokwakheka kwesistimu ye-membrane

Lapho amanye amabhizinisi esungula uhlelo lolwelwesi, anaka kakhulu imikhiqizo engenisiwe, futhi awakuqondi ukubaluleka kokwakhiwa kwesistimu.

Kulezi zinsuku, ukusebenza kolwelwesi oluthile lwasekhaya lwe-ultrafiltration sekufinyelele noma kudlule ngisho nezinga elithuthukisiwe lamazwe ngamazwe, isilinganiso sokusebenza kwezindleko siphezulu kakhulu kunolwelwesi olungenisiwe. Ezimweni ezingokoqobo, izinkinga zesistimu ye-membrane zivela kakhulu ekwakhiweni kobunjiniyela.

Lapho inqubo ye-UF+RO noma ye-MBR+RO yamukelwa, ukusebenza kabi kwesistimu ye-RO kuvame ukuhlotshaniswa nendawo enganele ye-MBR eselashwe ngaphambili noma i-UF membrane noma idizayini engenangqondo, okuholela kukhwalithi yamanzi yokungena ngokweqile yesistimu ye-RO.

Ukungaqondi kahle 5: Ubuchwepheshe be-Membrane bunamandla onke

Inqubo ye-Membrane inezici ze-turbidity ephansi yokuchithwa kwamanzi, ukuchithwa kombala, ukukhipha usawoti kanye nokuthambisa, njll. Kodwa-ke, ekwelapheni kwamanzi angcolile ezimbonini, ubuchwepheshe be-membrane ngokuvamile budinga ukuhlanganiswa nezinqubo zokwelashwa ze-physicochemical kanye ne-biochemical, ukuze udlale kangcono izinzuzo zokwelashwa okuthuthukisiwe kwe-membrane.

Ngaphezu kwalokho, ukwelashwa kwamanzi ulwelwesi ngokuvamile kunenkinga yokukhishwa kwamanzi agxilile, futhi kudinga nokusekelwa kobunye ubuchwepheshe, ngakho akunamandla onke.

Ukungaqondi kahle 6: Uma ulwelwesi oluningi, lungcono

Ngobubanzi obuthile, ukwandisa inani le-membrane kungathuthukisa ukuphepha kokukhiqizwa kwamanzi kwesistimu ye-membrane futhi kunciphise izindleko zokusebenza.

Kodwa-ke, lapho inani le-membrane likhuphuka ngaphezu kwenani elifanele, inani elilinganiselwe lokusabalala kwamanzi ku-membrane yeyunithi liyancipha, futhi ijubane lokugeleza kwamanzi ahlungiwe awela-ukugeleza liphansi kunenani elibalulekile, ukungcola okungaphezulu kwe-membrane akukwazi ukususwa, okuholela ekwandeni kokungcola nokuvinjelwa kwe-membrane, futhi ukusebenza kokukhiqizwa kwamanzi kuncipha.

Ngaphezu kwalokho, uma inani le-membrane likhuphuka, inani lamanzi okugeza lizokhula. Uma ipompo yokugeza kanye nenani lomoya ocindezelwe lingakwazi ukuhlangabezana nemfuneko yenani lamanzi okugeza endaweni ngayinye ye-membrane yeyunithi, kuyoba nzima ukugeza kahle, ukungcoliswa kwe-membrane kwanda, futhi ukusebenza kokukhiqizwa kwamanzi kuyathinteka, okubaluleke kakhulu ku-MBR noma i-UF membranes.

Ngaphandle kwalokho, lapho inani le-membrane likhuphuka, ukutshalwa kwezimali kwesikhathi esisodwa kanye nokwehla kwenani lohlelo lwe-membrane nakho kuzokhuphuka.
