Rov qab osmosis (RO) yog ib qho kev siv tshuab uas siv cov txheej txheem semi-permeable permeable rau cov kua sib cais. Nws lub hauv paus ntsiab lus yog tias dej raug yuam los ntawm qhov rov qab osmosis membrane nyob rau hauv siab, thaum yaj ntsev, organic teeb meem, colloids, kab mob, thiab lwm yam impurities cuam tshuam los ntawm daim nyias nyias, yog li purifying dej. Cov txheej txheem no zoo ib yam li kev pom meej heev, txo cov khoom tawg tag nrho (TDS) cov ntsiab lus hauv dej.
ROS systems muaj ntau yam kev siv. Hauv kev lag luam, nws yog ib feem tseem ceeb ntawm ntau cov txheej txheem tsim khoom. Piv txwv li, hauv kev lag luam hluav taws xob, kev tsim khoom thiab tu cov chips thiab kev sib koom ua ke hauv Circuit Court boards xav tau dej ultrapure nrog purity siab heev. Txawm tias qhov tsawg tshaj plaws impurities tuaj yeem cuam tshuam cov khoom lag luam, thiab RO yog cov kauj ruam tseem ceeb hauv kev npaj cov dej ntshiab no. Nyob rau hauv kev lag luam fais fab, boiler feedwater undergoes purification nws kim heev los tiv thaiv scaling thiab corrosion, kom muaj kev ruaj ntseg thiab ruaj khov ua hauj lwm ntawm cov khoom siv hluav taws xob; RO muab kev ruaj ntseg dej pretreatment rau lub hom phiaj no. Kev lag luam zaub mov thiab dej haus kuj tso siab rau RO thev naus laus zis kom tau txais cov dej ntshiab huv, ua kom cov khoom zoo sib xws thiab saj.
