Izisombululo ezingama-25 eziqhelekileyo zengxaki yetekhnoloji ye-osmosis ebuyela umva (icandelo lesi-2)
- Ngubani othengisa iiarhente zokucoca inwebu okanye obonelela ngeenkonzo zokucoca?
Iinkampani zokucoca amanzi zinokubonelela ngee-agent ezikhethekileyo zokucoca i-membrane kunye neenkonzo zokucoca, kwaye abasebenzisi banokuthenga ii-agent zokucoca ukucoca i-membrane ngokweengcebiso zeenkampani ze-membrane okanye ababoneleli bezixhobo.
- Ngowuphi owona mlinganiselo uphezulu ovumelekileyo we-silica kwi-inlet ye-reverse osmosis membrane?
Ubuninzi obuvumelekileyo be-silica buxhomekeke kubushushu, i-pH, kunye ne-scale inhibitor. Ngokuqhelekileyo, umlinganiselo ophezulu ovumelekileyo kumanzi agxininisiweyo yi-100ppm ngaphandle kokongezwa kwe-scale inhibitor. Ezinye ii-scale inhibitors zinokuvumela ubuninzi boxinzelelo lwe-silica kumanzi azingiweyo ukuba bube yi-240ppm. Nceda uqhagamshelane nomthengisi we-scale inhibitor.
umfanekiso
- Yintoni umphumo wechromium kwiinwebu ze-RO?
Ezinye iintsimbi ezinzima ezifana nechromium zinokubangela i-oxidation yeklorini, nto leyo ekhokelela ekuthotyweni kokusebenza okungenakujikwa kwenwebu. Oku kungenxa yokuba uzinzo lwe-Cr6+ emanzini lubi ngakumbi kunolo lwe-Cr3+. Kubonakala ngathi ii-ion zesinyithi ezine-valence ephezulu ye-oxidation zinempembelelo eyonakalisayo. Ngoko ke, ukuxinwa kwe-chromium kufuneka kuncitshiswe okanye ubuncinane i-Cr6 + kufuneka ithotywe ibe yi-Cr3 + kwicandelo lonyango lwangaphambili.
- Loluphi uhlobo lokwenziwa kwangaphambili olufunekayo ngokubanzi kwiinkqubo ze-RO?
Inkqubo eqhelekileyo yonyango yangaphambili iquka ukuhluzwa okurhabaxa (~80 microns) ukususa amasuntswana amakhulu, yongeza i-oxidants efana ne-sodium hypochlorite, emva koko ukuhluzwa okuchanekileyo ngesihluzo semultimedia okanye itanki yokucacisa, ukongeza ii-oxidants ezifana ne-sodium bisulfite ukunciphisa i-chlorine eshiyekileyo, kwaye ekugqibeleni ufakele isihluzo sokhuseleko phambi kokungena kwe-inlet. Umsebenzi wokucoca ukhuseleko, njengoko igama libonisa, kukusebenza njengeyona ndlela ikhuselekileyo yokukhusela amasuntswana amakhulu ngengozi ekonakalisa i-impeller kunye ne-membrane amacandelo epompo yoxinzelelo oluphezulu. Imithombo yamanzi enamanqanaba aphezulu eenxalenye eziqinileyo ezinqunyanyisiweyo zifuna amanqanaba aphezulu onyango lwangaphambili ukuhlangabezana neemfuno ezichaziweyo zokungena; Kwimithombo yamanzi enomxholo ophezulu wobunzima, kucetyiswa ukuba kusetyenziswe ukuthambisa okanye ukongeza i-asidi kunye ne-scale inhibitors. Kwimithombo yamanzi enomxholo ophezulu we-microbial kunye ne-organic, i-carbon activated okanye i-anti fouling inwebu izinto ziyafuneka.
11.Ngaba ukuguqula i-osmosis ukususa ii-microorganisms ezifana neentsholongwane kunye neebhaktheriya?
I-Reverse osmosis (RO) ixinene kakhulu kwaye inezinga eliphezulu lokususa iintsholongwane, i-bacteriophages, kunye neebhaktheriya, ubuncinane iilogi ze-3 okanye ngaphezulu (izinga lokususwa> 99.9%). Nangona kunjalo, kufuneka kuqatshelwe ukuba kwiimeko ezininzi, ii-microorganisms zisenokuthi zivelise kwakhona kwicala lokuvelisa amanzi kwi-membrane, exhomekeke kakhulu kwindibano, ukubeka iliso kunye neendlela zokulondoloza. Ngamanye amazwi, ukukwazi kwenkqubo ukususa i-microorganisms kuxhomekeke kakhulu ekubeni uyilo lwenkqubo, ukusebenza, kunye nolawulo lufanelekile kunokuba iipropati ze-membrane ngokwazo.
- Lithini ifuthe lobushushu kwimveliso yamanzi?
Okukhona iqondo lobushushu liphezulu, kokukhona imveliso yamanzi iphezulu, kwaye ngokuphambeneyo. Xa usebenza phantsi kweemeko eziphezulu zokushisa, uxinzelelo lokusebenza kufuneka luthotywe ukuze kugcinwe ukuveliswa kwamanzi okufanayo, kunye nokunye. Nceda ubhekisele kwizahluko ezifanelekileyo ze-TCF yokulungiswa kobushushu ukwenzela utshintsho kwimveliso yamanzi.
