?d? nzacha nke Ultrafiltration Membrane
2022-11-26
Tekn?z? akp?kp? an? Ultrafiltration b? tekn?z? nkewa akp?kp? ah? dabere na nyocha na nzacha, yana ?d?iche nr?gide d? ka isi ihe na-anya ?gb? ala. ?kp?r? ya b? isi b? ?mep?ta obere nr?gide nr?gide n'ak?k? ab?? nke akp?kp? ah? filtration, nke mere na ? ga-enye ike maka ?m? irighiri mmiri iji nweta obere oghere nke akp?kp? an? filtration, ma gbochie ad?gh? ?cha n'ak?k? nke ?z? nke akp?kp? ah? filtration, nke na-eme ka mmiri d? mma mgbe ?gw?gw? gas?r? na-agbaso ?kp?r? nd? d? mkpa.
N'ozuzu, ultrafiltration akp?kp? an? nwere ike ikewa n'ime es?tidem mgbali ultrafiltration akp?kp? an? na mp?ga ultrafiltration akp?kp? an? d? iche iche nke mmiri mbata. Nr?gide nke ime ultrafiltration akp?kp? ah? tekn?z? na-ebu ?z? tinye ns? n'ime eriri oghere, wee mee ka esemokwu d? iche iche mee ka ?m? irighiri mmiri banye n'ime akp?kp? ah? na ad?gh? ?cha na-an?gide na oghere eriri eriri. Nr?gide nr?gide ultrafiltration akp?kp? ah? d? n'èzí b? ihe d? iche na nr?gide d? n'ime, mgbe nr?gide nr?gide gas?r?, ?m? irighiri mmiri na-abanye n'ime eriri eriri oghere na ihe nd? ?z? ad?gh? ?cha na-egbochi n'èzí.
Ihe mkpuchi ultrafiltration na-ar? ?r? d? mkpa na ntinye nke tekn?z? akp?kp? an? ultrafiltration. Ultrafiltration akp?kp? ah? b? tumadi nke polyacrylonitrile, polyvinylidene fluoride, polyvinyl chloride, polysulfone na ihe nd? ?z?, Njirimara nke ihe nd? a na-ekpebi àgwà nke ultrafiltration akp?kp? ah?. N'ime usoro ngwa ngwa n'ezie, nd? ?r? d? mkpa kwes?r? ?t?le ?n?d? okpom?k?, nr?gide na-ar? ?r?, mkp?r? mmiri, mmet?ta nchacha mmiri na ihe nd? ?z? iji mee ka mmet?ta nke ultrafiltration membrane technology d?kwuo elu, ka ha wee gh?ta na ?chekwa na ?meghar? ihe onwunwe mmiri.
Ka ? d? ugbu a, a na-enwekar? ?z? nzacha ab?? na ntinye nke tekn?z? akp?kp? an? ultrafiltration: njedebe njedebe nw?r? anw? na nzacha gafere.
A na-akp?kwa nzacha ngw?cha nw?r? anw? nzacha zuru oke. Mgbe ihe kw?s?t?r?, turbidity, colloid ?d?naya na raw mmiri d? ala, d? ka mgbata mmiri, mmiri ala, elu mmiri, wdg, ma ? b? e nwere a siri ike imewe nke tupu ?gw?gw? usoro tupu ultrafiltration, ultrafiltration nwere ike iji zuru filtration mode. ?r?. N'oge nzacha zuru oke, mmiri niile na-agafe n'elu akp?kp? ah? ka ? gh?? mmep?ta mmiri, a na-egbochikwa ihe niile na-emet? ihe n'elu akp?kp? ah?. ? d? mkpa ka a wep? ya na ihe nd? mejup?tara akp?kp? ah? site na ?cha ikuku mgbe niile, ?sacha mmiri na ?sacha ya n'ihu, na ihicha kem?kal? mgbe niile.
Na mgbakwunye na nchacha nke njedebe nw?r? anw?, nzacha nchafe mmiri b?kwa usoro nzacha a na-ah?kar?. Mgbe ihe kw?s?t?r? na turbidity na raw mmiri d? elu, d? ka n'ime mmiri eweghachite oru ngo, cross-flow filtration mode na-ejikar?. N'oge nzacha gafere, ak?k? nke mmiri ntinye na-agafe n'elu akp?kp? ah? ka ? b?r? mmep?ta mmiri, a na-ahap?kwa ak?k? nke ?z? d? ka mmiri na-etinye uche, ma ? b? na-emeghar? ?z? wee laghachi na akp?kp? ah? n'ime ?n?d? mgbasa ozi. Ntucha nke gafere na-eme ka mmiri na-aga n'ihu na-aga n'ihu n'elu akp?kp? ah?. Igwe ?s? d? elu nke mmiri na-egbochi nch?k?ta nke ihe d? n'elu akp?kp? ah?, na-ebelata mmet?ta nke itinye uche na polarization, ma na-ebelata ngwa ngwa nke akp?kp? ah?.
? b? ezie na tekn?z? akp?kp? an? ultrafiltration nwere uru na-enwegh? at? na usoro eji eme ihe, ? p?tagh? na ? b? naan? tekn?z? akp?kp? an? ultrafiltration nwere ike iji naan? mee ka mmiri d? ?cha na-emet? mmiri n'ime usoro ?gw?gw? mmiri emet?. N'ezie, mgbe ? na-eche nsogbu nke ?gw?gw? mmiri emet? emet? ihu, nd? ?r? d? mkpa nwere ike ?gbal? ijik?ta tekn?z? ?gw?gw? d? iche iche na-agbanwe agbanwe. Iji meziwanye usoro ?gw?gw? nke ak?r?ngwa mmiri emet?gh? nke ?ma, ka e wee nwee ike ijide n'aka na ak?r?ngwa mmiri d? mma mgbe ?gw?gw? gas?r?.
N'ihi ihe d? iche iche na-ebute mmet? mmiri, ? b?gh? ihe niile na-emet? mmiri d? mma maka otu ?gw?gw? mmet? ah?. Nd? ?r? kwes?r? imeziwanye ezi uche nke njik?ta nke tekn?z? akp?kp? an? ultrafiltration, ma h?r? usoro ?gw?gw? kachas? mma maka ?sacha mmiri. Naan? n'?z? d? otú a, na mmalite nke ?h? na ar?m?r? nke mmet? mmiri na-emet? mmiri, nwere ike imeziwanye àgwà mmiri nke mmiri na-emer? emer? mgbe emechara ya.
N'ozuzu, ultrafiltration akp?kp? an? nwere ike ikewa n'ime es?tidem mgbali ultrafiltration akp?kp? an? na mp?ga ultrafiltration akp?kp? an? d? iche iche nke mmiri mbata.
