Menene Bambanci Tsakanin Membrane da RO?

Gabatarwa

A cikin yanayin tsaftace ruwa, membranes da baya osmosis Tsarin (RO) yana taka muhimmiyar rawa, kowanne yana tallan kayan aikin da ba a sani ba don fitar da gurɓataccen ruwa daga ruwa. Fahimtar bambance-bambancen tsakanin tacewa membrane da RO ƙirƙira yana da mahimmanci don zaɓar mafi kyawun tsarin kula da ruwa.

Sharuɗɗan "membrane" da "reverse osmosis (RO)" suna da alaƙa amma suna nuni ga ra'ayoyi daban-daban na hanyoyin magance ruwa:

Matattarar: Membrane wani shinge ne na musamman wanda ke ba da izinin wasu abubuwa su wuce yayin da suke toshe wasu. Membran da ake amfani da su a cikin jiyya na ruwa galibin zanen gado ne ko ƙullun da aka yi daga kayan da aka ƙera kamar su polyamide, polysulfone, ko samuwar acetic acid cellulose. Wadannan membranes suna da pores marasa iyaka ko tashoshi waɗanda ke ba da izinin shigar da atom ɗin ruwa musamman yayin da suke toshe gurɓatattun abubuwa kamar salts, barbashi, ƙwayoyin microscopic, da mahadi na halitta.

Remo Osmosis (RO): Juya kewaye osmosis hannun rigar gurɓataccen ruwa ne wanda ke amfani da ɓangarorin da ba za a iya jurewa ba don fitar da gurɓataccen ruwa daga ruwa. A cikin tsarin RO, ruwa yana ƙuntata ƙarƙashin nauyi ta cikin membrane, wanda ke ba da izinin barbashi na ruwa musamman don wucewa yayin da yake watsar da rushewar gishiri, ma'adanai, da sauran gurɓata. Ana tattara ruwan da aka tace da ke wucewa ta cikin membrane, yayin da abubuwan da aka ƙi su akai-akai ana zubar da su a matsayin ruwan sharar gida.

A cikin runtsi, membrane wani toshewar jiki ne wanda ke ba da izinin shigar da wasu abubuwa musamman, yayin da osmosis shine keɓantaccen gurɓataccen ruwa wanda ke amfani da membrane mai yuwuwa don fitar da gurɓataccen ruwa daga ruwa. RO shine aikace-aikacen ƙirƙira membrane a cikin maganin ruwa, kodayake ɗayan mafi fa'ida da dabarun amfani da nasara don ƙirƙirar ingantaccen ruwan sha.

Tace Matsala: Bayanin Mahimmanci

Tace membrane wata dabara ce da ake amfani da ita don raba ɓangarorin da ƙazanta daga maganin ruwa ta hanyar wucewa ta cikin membrane mai ƙyalli. Wannan membrane yana aiki azaman shamaki, yana barin wasu ƙwayoyin cuta kawai su wuce yayin da suke toshe wasu dangane da girmansu, siffarsu, da cajin su. Membrane tacewa ya ƙunshi matakai daban-daban kamar microfiltration, ultrafiltration, nanofiltration, da baya osmosis, kowanne yana biyan takamaiman buƙatun tacewa.

Mabuɗin Abubuwan Tacewa na Membrane

Microfiltration (MF) yana amfani da membranes tare da girman pore daga 0.1 zuwa 10 micrometers, yadda ya kamata cire daskararrun daskararru, kwayoyin cuta, da wasu ƙwayoyin cuta daga ruwa. Ultrafiltration (UF) yana amfani da membranes tare da ƙananan girman pore, yawanci tsakanin 0.01 zuwa 0.1 micrometers, don kawar da ƙwayoyin colloidal, macromolecules, da pathogens. Nanofiltration (NF) yana aiki akan matakin kwayoyin halitta, yana cire ions divalent, mahadi na kwayoyin halitta, da ƙananan barbashi. Reverse osmosis (RO), mafi girman nau'i na tacewa na membrane, yana amfani da babban matsin lamba don tilasta ruwa ta hanyar membrane mai yuwuwa, yadda ya kamata yana cire narkar da gishiri, ma'adanai, da gurɓatawa.

Mechanics na Reverse Osmosis (RO)

Baya osmosis (RO) tsari ne na tsaftataccen ruwa wanda ke amfani da membrane mai ratsa jiki don cire ions, kwayoyin, da manyan barbashi daga ruwan sha. A cikin tsarin RO, ana matsawa ruwa kuma an tilasta shi ta cikin membrane, yayin da aka bar gurɓataccen abu a baya, yana haifar da ruwa mai tsabta a gefe guda. Wannan tsari yana kawar da ƙazanta iri-iri yadda ya kamata, ciki har da gishiri, ma'adanai, karafa masu nauyi, da mahadi, samar da ingantaccen ruwan sha.

Halayen rarrabewa: Tacewar Membrane vs. Reverse Osmosis

tacewa membrane da baya osmosis (RO) su ne hanyoyin tsarkake ruwa guda biyu waɗanda ke amfani da membranes masu ƙarancin ƙarfi don cire ƙazanta daga ruwa.

Girman Pore:

Tacewar Membrane: Tacewar Membrane ya ƙunshi babban nau'in tafiyar matakai waɗanda suka haɗa da microfiltration (MF), ultrafiltration (UF), nanofiltration (NF), da juyawa osmosis (RO). Girman pore na membranes ya bambanta a cikin waɗannan fasahohin. Microfiltration yana da girman pore mafi girma, yawanci jere daga 0.1 zuwa 10 micrometers, yayin da ultrafiltration yana da ƙananan pores (0.01 zuwa 0.1 micrometers). Nanofiltration yana da ƙananan pores, yawanci jere daga 0.001 zuwa 0.01 micrometers. Reverse osmosis, a daya bangaren, yana da mafi girman girman pore, yawanci kasa da 0.001 micrometers, yana ba shi damar cire mafi girman kewayon gurɓata, gami da narkar da gishiri da ions.

Reverse Osmosis: RO membranes suna da ƙananan ƙananan pores waɗanda ke ba da damar kwayoyin ruwa kawai su wuce yayin da suke toshe narkar da gishiri, ma'adanai, kwayoyin cuta, ƙwayoyin cuta, da sauran gurɓatattun abubuwa.

Matsalar Aiki:

Filtration na Membrane: Hanyoyin tacewa na membrane kamar microfiltration, ultrafiltration, da nanofiltration yawanci suna aiki a ƙananan matsi idan aka kwatanta da baya osmosis.

Reverse Osmosis: Juya osmosis yana buƙatar matsi mafi girma na aiki don shawo kan matsa lamba osmotic da tilasta ruwa ta cikin membrane na semipermeable. Ana ba da wannan matsa lamba ta hanyar famfo a cikin tsarin RO.

Nau'o'in Abubuwan da Aka Cire:

Tace Membrane: Hanyoyin tacewa na membrane suna da tasiri wajen cire daskararrun daskararrun da aka dakatar da su, kwayoyin cuta, wasu ƙwayoyin cuta, da manyan ƙwayoyin cuta, dangane da girman ramin da ake amfani da su.

Reverse Osmosis: Reverse osmosis yana da ikon cire nau'ikan gurɓataccen abu, gami da narkar da gishiri, ma'adanai, karafa masu nauyi, mahaɗan kwayoyin halitta, ƙwayoyin cuta, ƙwayoyin cuta, da sauran ƙazanta, saboda ƙaramar pore ɗin sa da tsarin da ake tuƙi.

Aikace-aikace:

Tace Membrane: Ana amfani da fasahohin tacewa na membrane sau da yawa don aikace-aikace kamar bayanin ruwa, jiyya na ruwa, da kuma kawar da barbashi daga ruwa.

Reverse Osmosis: Reverse osmosis ana amfani da shi don samar da tsaftataccen ruwan sha, zubar da ruwan teku da ruwa mai laushi, aikin sarrafa ruwa na masana'antu, da sauran aikace-aikace inda ake buƙatar ruwa mai tsafta.

Fa'idodi da Aikace-aikace na Tacewar Membrane

Tacewar Membrane yana ba da fa'idodi da yawa, gami da haɓakawa, haɓakawa, da ingancin farashi. Ana amfani da shi sosai a masana'antu daban-daban, ciki har da magunguna, abinci da abin sha, fasahar kere-kere, da kuma kula da ruwan sha. Ana amfani da Microfiltration da ultrafiltration don bayyanawa da kuma haifuwa ta ruwa, yayin da ake amfani da nanofiltration don tausasa ruwa da cire mahaɗan kwayoyin halitta. Reverse osmosis yana samun aikace-aikace masu yawa a cikin tsire-tsire masu bushewa, tsarin tsaftace ruwa, da tsarin masana'antu da ke buƙatar ruwa mai tsafta.

Fa'idodi da Amfanin Reverse Osmosis (RO)

Fasahar Reverse osmosis (RO) tana alfahari da inganci mara misaltuwa wajen cire narkar da gishiri, ma'adanai, da gurɓata ruwa daga ruwa, yana mai da shi ba makawa a wuraren da ke fuskantar ƙarancin ruwa ko gishiri mai yawa. Ana amfani da tsarin RO a cikin wurin zama, kasuwanci, da saitunan masana'antu don samar da ruwan sha daga ruwan teku, ruwa mara kyau, ko gurɓataccen tushe. Bugu da ƙari, fasahar RO tana da alaƙa don samar da tsaftataccen ruwa don masana'antar harhada magunguna, ƙirƙira kayan lantarki, da samar da abin sha, yana tabbatar da ingantaccen ingancin samfur da bin ƙa'idodin ƙa'idodi.
