I-Nanofiltration (NF) kunye ne-Reverse Osmosis (RO) iiMembranes: Umgaqo-siseko, i-Aplikheshini, kunye nokuThenga iMarike

Imigaqo yeNanofiltration kunye ne-Reverse Osmosis

Iimbumba ze-Nanofiltration (NF) kunye ne-Reverse Osmosis (RO) i-membrane ziyingxenye yentsapho yokucoca iteknoloji yokucoca amanzi, isebenzisa uxinzelelo lokuhlukanisa ukungcola emanzini. Zombini ezi ntlobo ze-membrane ziyakwazi ukungena ngaphakathi, zivumela iimolekyuli zamanzi ukuba zidlule ngelixa zithintela ii-ion ezithile, iimolekyuli kunye namasuntswana.

I-Nanofiltration (NF) isebenza phantsi koxinzelelo oluphakathi (i-5-15 bar) kwaye inobungakanani bepore kwi-nanometer range (malunga ne-1-2 nanometers). Iinwebu ze-NF zikhetha ukuhluza ii-ion ezinkulu ze-divalent kunye ne-multivalent, iimolekyuli ze-organic, kunye ne-pathogens encinci, kodwa zivumela i-ion ze-monovalent (njenge-sodium kunye ne-chloride) ukuba idlule. Oku kukhetha kwenza i-NF ilungele izicelo apho ukukhutshwa ngokuyinxenye kufunwayo.

I-Reverse Osmosis (RO) isebenza phantsi koxinzelelo oluphezulu (i-15-70 bar) kwaye inobukhulu obuncinci be-pore, ngokuqhelekileyo ngaphantsi kwe-nanometer eyi-1. Oku kuvumela i-RO ukuba isuse uluhlu olubanzi lwezinto ezingcolileyo, kubandakanywa neetyuwa ezininzi ezinyibilikayo, i-organic compounds, kunye neentsholongwane, ezivelisa amanzi acocekileyo kakhulu. Iimbrane ze-RO zala ngaphezulu kwe-99% yeetyuwa ezinyibilikisiweyo, zizenza zilungele usetyenziso olufuna amanzi akumgangatho ophezulu.

Ukusetyenziswa kweNanofiltration kunye neReverse Osmosis Membranes

Zombini ii-membrane ze-NF kunye ne-RO zisetyenziswa ngokubanzi kumashishini amaninzi, ngokukodwa kunyango lwamanzi, ukutya kunye nesiselo, amayeza, kunye nokulungiswa kweekhemikhali.

Unyango lwamanzi: I-RO kunye ne-NF zisetyenziswa kakhulu kwizityalo ze-desalination ukubonelela ngamanzi okusela kumanzi olwandle okanye kwimithombo ye-brackish. I-membrane ze-RO zibonelela ngokucoca okuphezulu kwizicelo zamanzi eziphathwayo kunye ne-ultrapure, ngelixa i-NF ihlala ikhethwa ukuthambisa izicelo kunye nokususa ukungcola okuthile okufana ne-nitrate, i-pesticides, kunye neentsimbi ezinzima.

Ukutya kunye neSiselo: Iinwebu ze-NF zinceda ekusetyenzweni kobisi, apho zisetyenziselwa ukugxila kunye nokukhupha iiminerali zobisi kunye ne-whey. Iimbrane ze-RO, kwelinye icala, ziqeshwe ekugxininiseni ijusi yeziqhamo kunye nokucocwa kweswekile, ukubonelela nge-filtrate ekumgangatho ophezulu kunye nokuphucula ubomi beshelufu yemveliso.

I-Pharmaceuticals and Biotechnology: Kwishishini loxubo-mayeza, zombini i-NF kunye ne-RO zibalulekile ekuveliseni amanzi angcolileyo kunye ne-ultrapure ukwenzela ukuveliswa kwamachiza kunye neenkqubo ze-biotechnology. I-NF inokohlula iimolekyuli zendalo ezintsonkothileyo ngelixa i-RO ibonelela ngamanzi acocekileyo ayimfuneko kumachiza atofwayo.

I-Chemical Processing: Iimbumba ze-NF zisetyenziselwa ukususwa kwe-ion ekhethiweyo kwimveliso yeekhemikhali, apho iikhompawundi ezithile kufuneka zihlulwe okanye zigxininiswe. I-RO isetyenziselwe ukususa ukungcola okunyibilikayo, ukuqinisekisa ukucoceka kwemveliso kunye nokuzinza.

Amathemba eMarike

Imfuno ye-NF kunye ne-RO membranes inyuka ngokukhawuleza, iqhutywe yimfuno ekhulayo yamanzi akhuselekileyo, acocekileyo kunye nemimiselo engqongqo malunga nokukhutshwa kwamanzi amdaka. Izinto eziphambili ezinegalelo ekukhuleni kweemarike ziquka:

Ukunqongophala kwamanzi eHlabathini kunye nokuKhutshwa kwetyuwa: Ngokunqongophala kwamanzi ahlaziyekileyo kusanda kwihlabathi jikelele, ukukhutshwa kwetyuwa kusetyenziswa iinwebu ze-RO kube sisisombululo esibalulekileyo. I-NF ikwadlala indima ebalulekileyo ekusetyenzisweni kwakhona kwamanzi kunye nokusetyenziswa kwakhona, ngakumbi kwiindawo zezolimo kunye nezoshishino.

Ukonyuka kweSicelo soShishino: Ukutya nesiselo, amayeza, kunye nemizi-mveliso yeekhemikhali ziyanda kwihlabathi liphela, zibangela imfuno ebangwayo yamanzi akumgangatho ophezulu kunye nokuhluzwa okukhethiweyo. I-NF kunye ne-RO's application versatility ibhenela kuluhlu olubanzi lwamashishini afuna izisombululo zokucoca ezilungiselelweyo.
