Qhov sib txawv tseem ceeb ntawm kev pom thiab thim rov qab osmosis yog qhov pom siv lub lim nruab nrab rau kev sib cais, qhov rov qab osmosis siv ib feem permeable membrane rau txoj kev sib cais.
Filtration yog ib qho kev tshuaj ntsuam xyuas rau kev sib cais ntawm cov khoom ntawm cov kua. Rov qab osmosis yog ib txoj hauv kev ua kom huv dej uas siv ib nrab permeable membrane rau kev sib cais.
Dab tsi yog Lim?
Filtration yog ib qho kev tshuaj ntsuam xyuas rau kev sib cais ntawm cov khoom ntawm cov kua. Cov txheej txheem no yuav pab tshem tawm cov khib nyiab hauv cov kua los ntawm kev hla cov kua dej los ntawm qhov thaiv uas tuaj yeem tuav cov khoom ntawm lub cev, txhua yam, lossis kev ua haujlwm lom neeg. Ntawm no, cov kua dej tuaj yeem yog kua lossis roj. Cov kua peb tau txais tom qab pom yog "filtrate." Qhov thaiv peb siv rau kev pom yog "filter." Nws tuaj yeem yog lim dej los yog lim dej tob; Txawm li cas los xij, nws cuam tshuam cov khoom. Feem ntau, peb siv cov ntawv lim hauv chav kuaj kom pom.
Daim duab 01: Lim
Feem ntau, kev lim dej tsis yog txheej txheem tiav uas ua rau kom huv. Txawm li cas los xij, nws yog qhov tseeb piv rau decantation. Qhov ntawd yog vim qee cov khoom siv tuaj yeem dhau los ntawm cov lim dej thaum qee cov kua dej nyob hauv lub lim yam tsis tau mus rau qhov lim. Muaj ntau hom kev pom zoo, suav nrog kev pom kub, lim dej txias, nqus pom, thiab ultrafiltration.
Cov ntawv thov loj ntawm cov txheej txheem pom muaj xws li hauv qab no:
- Yuav cais cov kua thiab cov khoom hauv kev ncua
- kas fes lim: cais kas fes hauv av
- Siv lim kom cais cov hlau muaj txiaj ntsig thaum lub sijhawm mining
- Yuav cais cov muaju los ntawm cov tshuaj thaum lub sij hawm recrystallization txheej txheem hauv organic chemistry
- Lub tshuab hluav taws xob siv qhov pom los tiv thaiv lub tshuab hluav taws xob los ntawm fouling nrog particulates
Reverse Osmosis yog dab tsi?
Rov qab osmosis yog ib txoj hauv kev ntawm kev ua kom huv dej uas siv ib feem permeable membrane rau kev sib cais. Txoj kev no yog qhov tseem ceeb rau kev sib cais ntawm ions, tsis xav tau molecules, thiab cov khoom loj ntawm cov dej haus. Hauv cov txheej txheem no, peb tuaj yeem siv lub siab thov kom kov yeej osmotic siab (osmotic siab yog cov cuab yeej sib tsoo uas tau tsav los ntawm cov tshuaj muaj peev xwm sib txawv ntawm cov kuab tshuaj). Tsis tas li ntawd, rov qab osmosis yog qhov tseem ceeb hauv kev tshem tawm ntau hom tshuaj yaj thiab tshem tawm cov tshuaj lom neeg thiab hom kab mob xws li kab mob los ntawm dej.
Daim duab 02: Ib Qhov Rov Qab Osmosis System
Peb tuaj yeem siv rov qab osmosis rau ob qho tib si kev lag luam thiab kev tsim cov fwj dej portable. Thaum lub sij hawm tus txheej txheem no, lub solute yog khaws cia nyob rau hauv lub pressurized sab ntawm ib feem permeable daim nyias nyias thaum lub ntshiab kuab paug dhau los ntawm daim nyias nyias. Cov daim nyias nyias yog xaiv vim nws tsis pub cov khoom loj los yog ions mus rau hauv lub qhov hws, qhov uas nws tso cai rau cov khoom me me dhau mus dawb.
Dab tsi yog qhov txawv ntawm Kev Pom Zoo thiab Rov Qab Osmosis?
Feem ntau, rov qab osmosis txawv ntawm kev pom hauv cov txheej txheem ntawm cov kua dej ntws. Hauv cov txheej txheem rov qab osmosis, cov kua dej ntws tawm los ntawm daim nyias nyias uas yog ib feem permeable. Txawm li cas los xij, hauv cov txheej txheem pom, peb siv qhov nruab nrab pom. Yog li, qhov sib txawv tseem ceeb ntawm kev pom thiab rov qab osmosis yog qhov pom siv lub lim nruab nrab rau kev sib cais, qhov rov qab osmosis siv ib feem permeable membrane rau txoj kev sib cais.
Cov hauv qab no qhia txog qhov sib txawv ntawm kev pom thiab rov qab osmosis hauv daim ntawv teev npe rau ib sab ntawm kev sib piv.
Summary – Lim vs Reverse Osmosis
Filtration yog ib qho kev tshuaj ntsuam xyuas rau kev sib cais ntawm cov khoom ntawm cov kua. Rov qab osmosis yog ib txoj hauv kev ntawm kev lim dej uas siv ib nrab permeable membrane rau kev sib cais. Qhov sib txawv tseem ceeb ntawm kev pom thiab thim rov qab osmosis yog qhov pom siv lub lim nruab nrab rau kev sib cais, qhov rov qab osmosis siv ib feem permeable membrane rau cov txheej txheem sib cais.
