Txoj Cai Ua Haujlwm ntawm Reverse Osmosis Membrane
Rov qab Osmosis (RO) thev naus laus zis yog cov kua membrane sib cais thiab pom cov thev naus laus zis uas siv lub zog ua lub zog tsav.
RO MBR (winding type aromatic polyamide composite membrane) yog ib zaj duab xis nyias nrog cov khoom semi permeable uas siv cov ntaub ntawv tshwj xeeb thiab cov txheej txheem ua. Nws tuaj yeem xaiv nkag mus rau qee yam hauv kev daws teeb meem nyob rau sab nraud, yog li ua tiav kev ua kom huv, huv huv, lossis sib cais sib cais. Lim qhov tseeb ntawm 0 1-1 nanometers. Thaiv tag nrho cov ntsev ntsev ions thiab cov organic tebchaw uas muaj qhov hnyav molecular ntau dua 100.
Thaum tib lub ntim ntawm dilute tov thiab concentrated tov yog muab tso rau ntawm ob sab ntawm lub thawv, sib cais los ntawm ib tug semi permeable membrane nyob rau hauv nruab nrab, cov kuab tshuaj nyob rau hauv lub dilute tov yuav lawm dhau los ntawm lub semi permeable membrane thiab ntws mus rau lub concentrated tov. . Cov kua theem ntawm cov tshuaj concentrated sab yuav siab dua cov kua theem ntawm cov tshuaj diluted los ntawm ib qhov siab, ua rau lub siab sib txawv thiab ncav cuag osmotic equilibrium xeev. Qhov sib txawv siab no hu ua osmotic siab.
Yog hais tias lub siab ntau dua li osmotic siab yog siv rau ntawm cov concentrated tov, cov kuab tshuaj nyob rau hauv cov concentrated tov yuav ntws mus rau dilute tov, uas yog, cov kev taw qhia ntawm cov kuab flow yog opposite rau thawj cov kev taw qhia ntawm permeation. Cov txheej txheem no hu ua Reverse Osmosis.
