Musiyano pakati pemidziyo yeultrafiltration uye reverse osmosis midziyo
Musiyano mukuru pakati pe ultrafiltration membrane uye reverse osmosis ndiwo mutsauko wehukuru hwepore. Saizi yepore yechikepe chereverse osmosis membrane chikamu chimwe muzana cheiyo ultrafiltration membrane, uye iko kukwenenzverwa kwereverse osmosis membrane yakakwirira kupfuura iyo yeultrafiltration membrane. Ultrafiltration membrane ichienzaniswa nereverse osmosis membrane, reverse osmosis membrane aperture idiki zvakanyanya pane ultrafiltration membrane, reverse osmosis membrane aperture ndeye 0.0001 micron, ultrafiltration membrane aperture ndeye 0.001 micron. Saizi yepore ye reverse osmosis membrane chikamu chimwe muzana cheiyo ultrafiltration membrane, saka mvura yakasefa nereverse osmosis membrane yakachena kupfuura iyo yeultrafiltration membrane.
Ultrafiltration membrane inzira yekuparadzanisa membrane umo membrane ine porous asymmetric chimiro. Iyo filtration process igadziriso yekuparadzanisa nzira yakavakirwa pa mechanical sieving musimboti wekumanikidza musiyano pakati pemativi maviri e membrane, kushanda kumanikidza kunowanzo 0.01 kusvika 0.03Mpa, uye yakanaka pore saizi ye ultrafiltration membrane inenge 0.001 kusvika 0.01 microns. The interception molecular weight is 1,000-500,000 daltons, saka iyo ultrafiltration membrane yekuparadzanisa maitiro yaimboonekwa seyakanyatso kupatsanurwa kwemuviri.
Reverse osmosis membrane is artificial semi-permeable membrane ine chaiyo midziyo yakagadzirwa nekutevedzera biological semi-permeable membrane. RO ndiyo chidimbu cheChirungu che reverse osmosis membrane, chiChinese ndicho chirevo che reverse osmosis. Mvura yose inoyerera kubva pasi kuenda kumusoro. Apo mvura inomanikidzwa, mvura inoyerera kubva kumusoro kusvika pasi. Izvi zvinonzi musimboti we reverse osmosis. Iyo aperture ye reverse osmosis membrane inosvika mamiriyoni mashanu (0.0001 micron) yebvudzi remunhu. Utachiona nemavhairasi zvakakura zvakapetwa ka5,000, zvichingobvumira mamorekuru emvura chete uye mamwe mamineral ions anobatsira kupfuura, nepo kumwe kusvibiswa nesimbi dzinorema zvichidzingwa kubva mumapombi emvura yakasviba.
Iyo aperture ye reverse osmosis membrane ndeye 1/100 yeaperture ye ultrafiltration membrane, uye kukwenenzverwa kweiyo RO reverse osmosis membrane inosvika 0.0001 micron. Nekudaro, iko kukwenenzverwa kweiyo ultrafiltration membrane ndeye 0.001 microns. Naizvozvo, reverse osmosis membranes inogona kubvisa zvinorema simbi, mishonga yekuuraya zvipembenene, chloroform uye zvimwe zvinosvibisa makemikari kubva mumvura, asi ultrafiltration membranes haigone. Iyo ultrafiltration membrane inobvisa zvinosvibisa uye mabhakitiriya, uye reverse osmosis inovabvisa ine masimba ese.
