Nco ntsoov tias cov kua ntxhua khaub ncaws yuav tsum tsis txhob muaj cov teeb meem tshem tawm kom tiv thaiv cov spongy hauv qab txheej ntawm hollow fiber ntau los ntawm kev thaiv. Piv txwv li, ob lub ultrafilters tuaj yeem khiav ua ke thaum lub sijhawm rov qab ntxuav, thiab cov dej ntws ntawm ib qho ultrafilter tuaj yeem siv los ntxuav lwm qhov ultrafilter. Qhov no yuav tsum tau ua nyob rau hauv qis kev khiav hauj lwm siab kom tsis txhob rupture membrane. Lub sij hawm rov qab ntxuav nws feem ntau siv 20 mus rau 30 feeb. Lwm qhov yog kaw lub qhov hluav taws xob ntawm qhov permeate los ntawm kev siv tshuaj ntxuav, thiab siv cov kua pub thiab cov permeate los ntxuav. Txij li thaum tus nqi ntws ntawm cov kua pub rau hauv cov kab noj hniav hollow fiber ntau yog siab, qhov ntws siab poob yog loj. Tom qab kaw lub qhov hluav taws xob ntawm lub permeate, lub siab ntawm cov fibers yog roughly sib npaug rau qhov nruab nrab tus nqi ntawm lub siab nyob rau hauv lub fibers. Lub siab sab hauv ntawm qhov inlet seem ntawm hollow fiber ntau dua, ua rau pom kev; lub siab sab nraud ntawm qhov hluav taws xob qhov hluav taws xob ntawm cov fiber ntau dua, thiab cov filtrate ntws rov qab rau hauv cov fiber ntau. Nyob rau hauv lub puab kab noj hniav, lub permeate circulates sab hauv thiab sab nraum lub hollow fiber. Qhov rov qab lim dej ntws thiab cov kua dej nrawm nrawm tuaj yeem tshem tawm cov av uas tso tawm. Tsis ntev los no, ib qho kev txhim kho yog siv ob pawg ntawm lub siab sab hauv hollow fiber ntau ua ke. Ultrafiltrate yog siv los thim rov qab lwm txheej ntawm hollow fiber ntau, thiab kev sib pauv yog nqa tawm tom qab lub sijhawm. Feem ntau, nws ua hauj lwm rau 10 feeb thiab backflushing rau 1min.
Txoj kev no ntawm backflushing thaum ua haujlwm tuaj yeem tiv thaiv kom tsis txhob txhaws ntawm daim nyias nyias pores thiab ua rau daim nyias nyias hla. Cia ua hauj lwm nyob rau theem siab. Txoj kev ua haujlwm no cuam tshuam los ntawm kev pom tias nws yuav tsum tau tos kom txog thaum lub membrane fouled ua ntej nws tsis ua haujlwm rau kev ntxuav. Nws tsis xav tau cov neeg ua haujlwm tu thiab tsis tas yuav tshem tawm cov membrane sib dhos. Nws yog ib txoj kev zoo heev. Kev tswj ib feem ntawm qhov hloov pauv muaj qhov xav tau ntau dua, txwv tsis pub lub neej ntawm daim nyias nyias yuav raug cuam tshuam.
Piv txwv li, sab nraud siab hollow fiber ntau tuaj yeem ntxuav los ntawm txoj kev isobaric. Thaum yaug dej, thawj kauj ruam yog kom depressurize lub lag luam, kaw lub qhov hluav taws xob ultrafiltrate thiab nce tus nqi ntws ntawm cov kua roj inlet. Nyob rau lub sijhawm no, cov kab noj hniav sab hauv siab ntawm cov hollow fiber ntau nce mus txog thaum nws nce mus txog qhov kev ua haujlwm zoo ib yam li cov kab noj hniav sab nraud ntawm cov fiber ntau, kom lub siab sib txawv ntawm sab hauv thiab sab nraud ntawm daim nyias nyias yog xoom, thiab tuav cov kua nplaum. Cov molecules ntawm daim nyias nyias yuav raug tshem tawm hauv cov tshuaj thiab tawm nrog cov dej concentrated.
Isobaric flushing yog tsim rau hollow fiber ntau daim nyias nyias. Rau hollow fiber membrane modules, cov kev tsis zoo siab tu txoj kev kuj yuav siv tau, uas yog, lub functional nto ntawm daim nyias nyias yog nyob rau hauv ib tug tsis zoo siab lub xeev los ntawm kev nqus, thiaj li mus tshem tawm cov pa phem thiab rov ua hauj lwm ntawm daim nyias nyias. Qhov zoo dua yog tias thaum lub siab sab nraud ntawm daim nyias nyias yog atmospheric siab, qhov siab tshaj plaws qhov sib txawv ntawm sab hauv thiab sab nraud ntawm daim nyias nyias yog ib qho atmospheric siab, daim nyias nyias tsis yooj yim puas, thiab nws cov nyhuv tu zoo dua li isobaric tu.
