Intshayelelo kwiiNkqubo zokuHlanza iiMembrane
Iinkqubo zokucoca i-membrane ziye zaguqula indlela esicoca ngayo amanzi kwaye sahlula izinto ezahlukeneyo. Ezi nkqubo zisebenzisa i-membrane enemingxuma ukususa ngokukhetha amasuntswana, ii-ion, okanye iimolekyuli kumjelo wolwelo. Ukuqonda indlela ezisebenza ngayo iinkqubo zokucoca i-membrane kubalulekile kwabo basebenza kwizityalo zonyango lwamanzi, kwiilebhu, okanye kumashishini apho ukwahlula kunye nokucoca kuyinkqubo ebalulekileyo. Eli nqaku lijolise ekuboneleleni ngesikhokelo esipheleleyo kwiinkqubo zokucoca i-membrane, kubandakanya iintlobo zazo, inkqubo, ukusetyenziswa, kunye neenzuzo.
Iintlobo ze-Membrane Filtration
Kukho iintlobo ezahlukeneyo zeenkqubo zokucoca i-membrane, nganye iyilwe ngeempawu ezithile kunye nokusetyenziswa. Ezi ntlobo zimbini ziphambili ziinkqubo zokucoca eziqhutywa luxinzelelo kunye neenkqubo zokucoca eziqhutywa luxinzelelo.
1. Iinkqubo zokuhluza eziqhutywa luxinzelelo:
Iinkqubo eziqhutywa luxinzelelo zixhomekeke ekusetyenzisweni koxinzelelo lwangaphandle ukunyanzelisa ulwelo ukuba ludlule kwi-membrane. Inkqubo yokucoca eqhutywa luxinzelelo esetyenziswa kakhulu yi-Reverse Osmosis (RO), apho isinyibilikisi sidlula ukusuka kwindawo enoxinzelelo oluphezulu ukuya kwi-solute concentration ephantsi kusetyenziswa i-membrane engakwazi ukungena emanzini. Le nkqubo isusa ngokufanelekileyo ii-ion, izinto eziqinileyo ezinyibilikisiweyo, kunye nezinye izinto ezingcolileyo, nto leyo eyenza ukuba ibe luncedo ekususeni ityuwa, ekucoceni amanzi, nasekunyangweni kwamanzi amdaka.
2. Iinkqubo zokuhluza eziqhutywa kukuxinanisa:
Iinkqubo zokucoca eziqhutywa luxinzelelo, ezaziwa ngokuba ziinkqubo eziqhutywa luxinzelelo lwe-concentration gradient, zisebenzisa umahluko kuxinzelelo olunyibilikayo ukuqhuba ukwahlukana. Enye yeenkqubo zokucoca yi-Dialysis, apho i-concentration gradient kwi-membrane ivumela iimolekyuli ezincinci ukuba zidlule ngelixa zigcina ezinkulu. Le ndlela isetyenziswa kwiinkalo zonyango ekususeni inkunkuma egazini kwizigulana ezinengxaki yezintso.
Inkqubo yokuhluza iMembrane icacisiwe
Umgaqo obalulekileyo emva kokuhluzwa kwe-membrane kukukwazi kwe-membrane ukuvumela ngokukhetha amasuntswana athile okanye iimolekyuli ukuba zidlule ngelixa zigcina ezinye. Olu khetho lufezekiswa ngeendlela ezahlukeneyo, kubandakanya ukukhutshwa kobungakanani, ukukhutshwa kwe-charge, kunye nokutsalwa kwe-adsorption.
1. Ukukhutshwa kobungakanani:
Ukususwa kobungakanani yenye yeendlela eziphambili ezisetyenziswa ziinkqubo zokucoca iimembrane. Iimembrane ezinobukhulu beembobo ezichaziweyo zivumela iimolekyuli ezincinci kunobukhulu beembobo ukuba zidlule ngelixa zivimba amasuntswana amakhulu. Indlela yokususwa kobungakanani isusa izinto eziqinileyo ezixhonyiweyo, ii-colloids, iibhaktheriya, kwanezinye iintsholongwane ezivela kumjelo wolwelo.
2. Ukungabandakanywa kweNtlawulo:
Ezinye ii-membrane zixhomekeke kumandla e-electrostatic ukuze zahlule ii-particles. Ngokufaka izinto ze-polymer ezitshajiweyo, ezi membrane zinokugxotha ii-ion okanye ii-particles ezinee-charges ezifanayo ngelixa zivumela ii-molecules ezitshajiweyo ezichaseneyo ukuba zidlule. Le ndlela iluncedo kakhulu ekususeni ii-ions ezinyibilikisiweyo okanye ii-heavy metals emanzini.
3. Ukufunxwa:
Iimembrane ezithile zenzelwe ukufunxa iimolekyuli ezithile kumphezulu wazo. Ezi membrane, ezidla ngokugqunywa nge-activated carbon okanye ezinye izinto ezifunxa, zigcina iimolekyuli ekujoliswe kuzo ngokuzivumela ukuba zinamathele kumphezulu wemembrane ngelixa zivumela ulwelo oluseleyo ukuba ludlule.
