IiFiltrashethi zoBunzulu vs iiFiltra zeMembrane: Yeyiphi iFiltration

Itekhnoloji Ngaba Ifanelekile Kwinkqubo Yakho?

Ukukhetha phakathiubunzuluisihluzoamashitikwayeinwebuizihluzisesinye sezona zigqibo zibalulekileyo kuyo nayiphi na inkqubo yokuhluza ulwelo. Nokuba uvelisa iwayini, ibhiya, iioyile ezityiwayo, amayeza, izinto zokuthambisa, okanye iikhemikhali ezikhethekileyo, isihluzo osikhethayo sichaphazela ngokuthe ngqo umgangatho wemveliso, ukusebenza kakuhle kwemveliso, iindleko zokusebenza, kunye nobomi bezixhobo.

Iinjineli ezininzi zicinga ukuba isihluzo se-membrane sihlala sinikeza ukuhluzwa okungcono kuba sine-micron echaziweyo. Nangona izihluzo ze-membrane zibonelela ngokugcinwa kwamasuntswana ngokuchanekileyo, azisoloko zisisisombululo esilungileyo. Enyanisweni, ukusebenzisa isihluzo se-membrane kulwelo olunemithwalo ephezulu yamasuntswana kudla ngokukhokelela ekuvalekeni ngokukhawuleza, uxinzelelo olwandileyo, ukutshintshwa rhoqo, kunye neendleko eziphezulu zemveliso. Kwelinye icala,ubunzuluisihluzoamashitibabalasele ekuphatheni imithwalo emikhulu yongcoliseko ngelixa begcina amazinga aphezulu okuhamba kwamanzi, nto leyo eyenza ukuba ibe lolona khetho lukhethwayo lokucacisa kunye nokuhluzwa kwangaphambili kumashishini amaninzi.

Umbuzo wokwenyani awunjalo"Yeyiphi i-filter engcono?"Endaweni yoko,"Yeyiphi i-filter engcono kwinkqubo yakho ethile?"Esi sikhokelo sithelekisaukuhluza ubunzulu vs ukuhluza i-membranekuzo zonke izinto ezibaluleke kakhulu:

Ukuqonda iiTekhnoloji zokuHluza iiShishini

Ukucoca kwimizi-mveliso kungaphezulu kakhulu kokususa nje amasuntswana kulwelo. Injongo iyahluka ngokuxhomekeke kwisicelo. Indawo yokwenza iwayini inokufuna ukususa inkungu ngelixa igcina iikhompawundi zevumba. Umenzi wamayeza unokufuna ukucoca okungeyongozi okuqinisekisiweyo. Umvelisi weoyile etyiwayo ugxila ekwandiseni ukuveliswa kwayo ngelixa enciphisa ukulahleka kwemveliso. Ngenxa yokuba ezi njongo zahlukile, ubuchwepheshe bokucoca buye batshintsha baba ziindlela ezimbini ezahlukeneyo:ukuhluza ubunzulukwayeukuhluza inwebu.

Zithini UbunzuluIsihluziAmaphepha?

Amaphepha okucoca anzulu enziwe yi-matrix etyebileyo, enemingxuma eyenziwe ngeefayibha ze-cellulose, izixhobo zokucoca ezifana nomhlaba we-diatomaceous okanye i-perlite, kunye nee-resin ezikhethekileyo ezibonelela ngamandla olwakhiwo kunye nokutsalwa kwe-electrokinetic. Endaweni yokubamba ukungcola kuphela kumphezulu, amasuntswana abanjwa kuyo yonke i-density ye-filter media. Olu lwakhiwo luneemilinganiselo ezintathu luvumela isihluzi ukuba sigcine ukungcola kobukhulu obahlukeneyo ngelixa sigcina amazinga okuhamba azinzileyo kwixesha elide lemveliso.

Ngenxa yokuba izinto ezingcolisayo zisasazwa kuyo yonke indawo kunokuba ziqokeleleke kumphezulu omnye, amaphepha okucoca ubunzulu abonisa amandla akhethekileyo okugcina ukungcola. Asetyenziswa kakhulu ekucaciseni iziselo, iioyile ezityiwayo, imihluzi yokubilisa, ii-enzymes, i-gelatin, izinto zokuthambisa, kunye neekhemikhali ezintle.

Zithini iiFilters zeMembrane?

Izihluzi zeMembrane zisebenzisa i-membrane encinci yepolymeric enobukhulu beembobo ezilawulwa kakhulu. Ngokungafaniyo nezihluzi zobunzulu, izihluzi ze-membrane zixhomekeke kakhulu kwiukuhluza umphezuluAmasuntswana amakhulu kunobukhulu be-pore agcinwa kumphezulu we-membrane, ngelixa iimolekyuli ezincinci zidlula. Izinto eziqhelekileyo ze-membrane ziquka i-PES, i-PVDF, i-Nylon, i-PTFE, kunye ne-cellulose acetate, kunye nobukhulu be-pore buhlala buqala kwi-0.1 ukuya kwi-1.0 μm yokucoca nge-microfiltration.

Ubuchule babo bokugcina ngokupheleleyo izinto ezisetyenzisiweyo kwenza izihluzi ze-membrane zibe zezona zifanelekileyo ekuhluzweni okungeyontsholongwane, ekususweni kweentsholongwane, kunye namanyathelo okugqibela okucoca apho ukuhambelana kunye nokuthobela imithetho kubalulekile.

Indlela Esebenza Ngayo Indlela Yokucoca Ngayo

Umgaqo wokucoca ubunzulu

Khawuthelekelele ugalela amanzi anodaka kwisiponji esityebileyo. Njengoko ulwelo luhamba kwisiponji, amasuntswana abambeka kubunzulu obahlukeneyo endaweni yokuba aqokeleleke phezu komhlaba kuphela. Le yindlela esisiseko yokwenza oku.ukuhluza ubunzuluiyasebenza. Amasuntswana amakhulu abanjwa kufutshane nomphezulu ongasentla, amasuntswana aphakathi angena nzulu, kwaye ukungcola okuncinci kugcinwa kuyo yonke inethiwekhi yangaphakathi yeembobo.

Ngaphandle kokuthintela ngoomatshini, amaphepha amaninzi esihluzo sobunzulu asebenzisa i-electrokinetic adsorption. I-positive charged filter media itsala ii-colloids ezitshajiswe kakubi kunye namasuntswana amancinci ebengadlula kwii-mechanical pores. Olu dibaniso lokugcinwa ngoomatshini kunye nombane luphucula kakhulu ukusebenza kakuhle kokucacisa, ngakumbi kwiziselo, ulwelo lwebhayoloji, kunye nezisombululo ezineeproteni.

Ulwelwesi(Umphezulu) Umgaqo wokucoca

Ukuhluzwa kwe-membrane kusebenza njenge-sefu echanekileyo. Imbobo nganye inobukhulu obumiselweyo, ivumela amasuntswana angaphantsi kwereyithingi ukuba adlule ngelixa egcina ukungcola okukhulu kumphezulu. Ngenxa yokuba phantse zonke ukungcola ziqokelelana kumaleko omnye, izihluzi ze-membrane zibonelela ngokusebenza okuqikelelweyo kokugcina kodwa kancinci kancinci ziphuhlisa umaleko wekhekhe onyusa ukwehla koxinzelelo kwaye unciphise ukuhamba kwamanzi.

Olu phawu luchaza isizathu sokuba izihluzi ze-membrane zihlala zifakelwa emva kwamanqanaba angaphambi kokuhluzwa. Ukususa amasuntswana amakhulu phezulu komsinga kwandisa ubomi be-membrane kwaye kunciphisa iindleko zokusebenza.

Ubunzulu bokucoca vs.UlwelwesiUthelekiso lokuhluza

Ukuchaneka kokuhluza

Umahluko omkhulu usekwe ekugcinweni kwamasuntswana. Amaphepha ezihluzo zobunzulu ngokubanzi anazoukalisho oluqhelekileyo, oko kuthetha ukuba zibamba ipesenti ephezulu yamasuntswana ajikeleze ubungakanani obulinganisiweyo ngelixa zigcina izinto ezincinci ezingcolisayo ngokusebenzisa ukufunxwa kunye neendlela zokuhamba ezigosogoso. Izihluzi zeMembrane zibonelelauphononongo olupheleleyo, ebonelela ngokususwa kwamasuntswana okuqinileyo nokuphindaphindekayo ngakumbi.

Umgangatho wohambo

Izinga lokuhamba kwamanzi kulapho izihluzi zobunzulu zihlala ziphumelela khona izihluzi ze-membrane. Ulwakhiwo lwazo oluvulekileyo nolunemingxuma luvumela ulwelo olune-solids ezixhonyiweyo eziphezulu ukuba ludlule ngokulahlekelwa koxinzelelo oluphantsi. Izihluzi ze-membrane, xa kuthelekiswa, zifumana ukunyuka koxinzelelo ngokukhawuleza kuba amasuntswana aqokelelana phezu komhlaba, nto leyo ethintela ukuhamba kwamanzi. Iingxelo zoshishino zihlala zichonga amazinga aphantsi okuhamba kwamanzi njengomda oyintloko wokuhluzwa kwe-membrane.

Umthamo wokubamba ukungcola

Iifayile zobunzulu zenzelwe ngokukodwa ukugcina ukungcola okuninzi. I-matrix yazo enamacala amathathu isasaza izinto eziqinileyo kuyo yonke imithombo, nto leyo ebambezela kakhulu ukuvaleka. Iifiltha ze-membrane zinomthamo omncinci wokubamba ukungcola kuba phantse zonke iisuntswana zihlala phezu komphezulu, nto leyo ebangela ukuba zibe semngciphekweni wokungcoliswa ngokukhawuleza xa kusetyenzwa ulwelo olungcolileyo.

Uthelekiso lweendleko

Ixabiso lokuqala lokuthenga lidla ngokuthanda amaphepha okucoca ubunzulu. Abiza kancinci kwaye adla ngokufuna ukutshintshwa okuncinci kwizicelo zokucacisa.
