Izixazululo ezijwayelekile ezingama-25 zenkinga yobuchwepheshe be-osmosis membrane (Ingxenye 2)

7. Ubani othengisa ama-ejenti okuhlanza ulwelwesi noma ohlinzeka ngezinsizakalo zokuhlanza?

Izinkampani zokuhlanza amanzi zingahlinzeka ngama-ejenti akhethekile okuhlanza ulwelwesi kanye nezinsizakalo zokuhlanza, futhi abasebenzisi bangathenga ama-ejenti okuhlanza ulwelwesi lokuhlanza ngokweziphakamiso zezinkampani ze-membrane noma abahlinzeki bemishini.

8. Ingakanani ukugxiliswa okuphezulu okuvunyelwe kwe-silica endaweni yokufaka ulwelwesi lwe-osmosis ehlane?

Isilinganiso esiphezulu esivumelekile se-silica sincike ezingeni lokushisa, i-pH, ne-scale inhibitor. Ngokuvamile, ukugxila okuphezulu okuvumelekile emanzini agxilile kungu-100ppm ngaphandle kokwengezwa kwe-scale inhibitor. Amanye ama-scale inhibitors angavumela ukugcwala okukhulu kwe-silica emanzini agxilile ukuthi kube ngu-240ppm. Sicela uxhumane nomhlinzeki we-scale inhibitor.

9. Uyini umphumela we-chromium kulwelwesi lwe-RO?

Izinsimbi ezithile ezisindayo ezifana ne-chromium zingase zenze i-oxidation ye-chlorine, okuholela ekonakaleni kokusebenza okungenakuhlehliswa kolwelwesi. Lokhu kungenxa yokuthi ukuzinza kwe-Cr6+ emanzini kubi kakhulu kunaleyo ye-Cr3+. Kubonakala sengathi ama-ion ensimbi ane-valence ephezulu ye-oxidation anomphumela olimazayo onamandla. Ngakho-ke, ukugcwala kwe-chromium kufanele kwehliswe noma okungenani i-Cr6+ yehliselwe ku-Cr3+ esigabeni sokwelashwa kwangaphambili.

10. Hlobo luni lokucubungula ngaphambilini oludingekayo ngokuvamile kumasistimu e-RO?

Uhlelo olujwayelekile lokwelapha ngaphambilini luqukethe ukuhlunga okumahhadladla (~80 microns) ukuze kukhishwe izinhlayiya ezinkulu, kwenezela ama-oxidants afana ne-sodium hypochlorite, bese kuhlungwa ngokunemba ngesihlungi se-multimedia noma ithangi lokucacisa, ukwengeza oksijini njenge-sodium bisulfite ukuze kuncishiswe i-chlorine esele, futhi ekugcineni ufake isihlungi sokuphepha ngaphambi kokungena kokucindezela okukhulu. Umsebenzi wesihlungi sokuvikeleka, njengoba negama liphakamisa, ukusebenza njengesinyathelo sokuphepha sokugcina ukuvimbela izinhlayiya ezinkulu zengozi ukuthi zingalimazi i-impeller kanye nezingxenye ze-membrane zepompo yokucindezela okuphezulu. Imithombo yamanzi enamazinga aphezulu ezinhlayiya eziqinile ezimisiwe ngokuvamile idinga amazinga aphezulu okwelashwa kwangaphambili ukuze ihlangabezane nezimfuneko ezishiwo zokungena kwamanzi; Ngemithombo yamanzi enokuqukethwe kokuqina okuphezulu, kunconywa ukusebenzisa ukuthambisa noma ukwengeza ama-acid kanye nama-scale inhibitors. Ngemithombo yamanzi enokuqukethwe okuphezulu kwe-microbial kanye ne-organic, i-carbon activated noma i-anti fouling membrane element nayo iyadingeka.

11.Ingabe i-osmosis ehlehlayo ingasusa ama-microorganisms afana namagciwane nama-bacteria?

I-Reverse Osmosis (RO) iminyene kakhulu futhi inezinga eliphezulu kakhulu lokususwa kwamagciwane, ama-bacteriophages, namagciwane, okungenani amalogi angu-3 noma ngaphezulu (izinga lokususwa>99.9%). Kodwa-ke, kufanele kuqashelwe ukuthi ezimweni eziningi, ama-microorganisms angakwazi ukuzala ohlangothini olukhiqiza amanzi lwe-membrane, okuncike kakhulu ekuhlanganiseni, ekuqapheleni nasekunakekeleni izindlela. Ngamanye amazwi, ikhono lesistimu lokususa ama-microorganisms lincike kakhulu ekutheni ukwakheka kwesistimu, ukusebenza, nokuphatha kufanelekile yini kunezakhiwo zezingxenye ze-membrane ngokwazo.

12. Uyini umthelela wokushisa ekukhiqizeni amanzi?

Uma izinga lokushisa liphakeme, ukukhiqizwa kwamanzi aphezulu, futhi ngokuphambene nalokho. Lapho usebenza ngaphansi kwezimo zokushisa eziphakeme, ingcindezi yokusebenza kufanele yehliswe ukuze kugcinwe ukukhiqizwa kwamanzi okufanayo, futhi ngokuphambene nalokho. Sicela ubheke izahluko ezifanele zesici sokulungisa izinga lokushisa i-TCF ukuze uthole izinguquko ekukhiqizweni kwamanzi.
