RO dej kho qhov system, tseem hu ua rov qab osmosis dej kho qhov system, yog cov txheej txheem sib cais membrane tsim nyob rau hauv lub xyoo caum, lub hauv paus ntsiab lus yog tias cov dej nyoos nyob rau hauv qhov kev txiav txim siab los ntawm kev rov qab osmosis membrane, cov kuab tshuaj nyob rau hauv cov dej diffuses los ntawm siab concentration mus rau tsawg concentration kom ua tiav lub hom phiaj ntawm kev sib cais, purification thiab concentration, vim hais tias nws yog opposite rau cov kev taw qhia ntawm nkag mus rau hauv cov xwm, yog li nws yog hu ua rov qab osmosis. Rov qab osmosis dej kho tshuab tuaj yeem tshem tawm cov kab mob, kab mob, colloids, organic teeb meem thiab ntau dua 98 feem pua ntawm cov ntsev yaj ntawm dej. Txoj kev no muaj cov yam ntxwv ntawm tus nqi qis, kev ua haujlwm yooj yim, qib siab ntawm automation thiab ruaj khov effluent zoo. Piv nrog rau lwm txoj kev kho dej ib txwm muaj, nws muaj qhov pom tseeb zoo thiab siv dav hauv kev kho dej ntsig txog kev lag luam.
