I-Membrane yokukhutshwa kwetyuwa emanzini olwandle
Inkcazo:
Ukunqongophala kwamanzi ngumba wehlabathi ofuna izisombululo ezintsha. Ukukhutshwa kwetyuwa emanzini olwandle kuye kwavela njengobuchwephesha obubalaseleyo ukuhlangabezana nemfuno ekhulayo yemithombo yamanzi ahlaziyekileyo. Ukuphumelela kokutshatyalaliswa kwamanzi olwandle kuxhomekeke kakhulu ekusebenzeni kunye nokusebenza kwe-membrane esetyenziswe kwinkqubo. Iitekhnoloji ezimbini eziphambili ze-membrane eziye zafumana ukuthandwa zii-membrane zokususa ityuwa emanzini olwandle kunye neenwebu ze-osmosis ezibuyela umva.
Iimbrane zokukhupha ityuwa emanzini kunye neenwebu ze-osmosis ezibuyela umva zisetyenziswa kwizityalo zokukhupha ityuwa ukuze zahlule ityuwa kunye nobunye ukungcola kumanzi olwandle. Nangona kunjalo, ziyahluka ngesakhiwo, ukwakheka kunye nokusebenza. Ukuqonda lo mahluko kubalulekile ekukhetheni itekhnoloji ye-membrane efanelekileyo kwizicelo ezithile.
I-Membrane yokukhutshwa kwetyuwa emanzini:
Iinwebu zokukhupha ityuwa emanzini olwandle ziyilelwe ngokukodwa iimeko ezirhabaxa kunye namanqanaba aphezulu etyuwa ekudibaneni nawo kwizityalo zokukhupha ityuwa. Ezi membrane zenziwe ngezinto ezahlukeneyo, kubandakanya i-cellulose acetate, i-polyamide, kunye ne-polysulfone. Banomaleko otyebileyo osebenzayo xa kuthelekiswa neenwebu ze-osmosis ezibuyela umva, ezibenza bakwazi ukumelana noxinzelelo olumandla olufunekayo ekukhutshweni kwetyuwa.
Enye yeenzuzo eziphambili zokukhupha ityuwa emanzini olwandle kukukwazi ukuxhathisa ukuchasana nokungcoliswa. Ukungcola kwenzeka xa i-particulate matter iqokelela kwi-membrane surface, ukunciphisa ukusebenza kwayo. Ukubunjwa okukodwa kweembrane zokukhupha ityuwa emanzini olwandle kuthintela ukungcola, ukuqinisekisa ukusebenza okungaguquguqukiyo nokuthembekileyo kwixesha elongeziweyo.
Reverse Osmosis Membrane:
Iimbrane ze-osmosis ezibuyela umva zisetyenziswa ngokubanzi kwizicelo ezahlukeneyo, kubandakanya ukukhupha ityuwa, ukucocwa kwamanzi amdaka, kunye neenkqubo zokucoca. Ezi nwebu zenziwa ngokuqhelekileyo kwizinto ezidibeneyo zefilimu ebhityileyo, equka umaleko wepolymer obhityileyo obekwe kwizinto ezixhasayo. Umaleko obhityileyo osebenzayo wenza ukuba amazinga aphezulu okuguquguquka kwamanzi ngelixa egcina amandla abalaseleyo okwala ityuwa.
Xa kuthelekiswa neenwebu zokukhupha ityuwa emanzini olwandle, iimbrane ze-osmosis ezibuyela umva zisesichengeni sokonakala ngenxa yomaleko wazo obhityileyo osebenzayo kunye nemingxuma emincinci. Nangona kunjalo, ukuqhubela phambili kwitekhnoloji ye-membrane kukhokelele kuphuhliso lwe-anti-fouling kunye nemigaqo yokucoca ephuculweyo, ukunciphisa imiba enxulumene nokungcola.
Uthelekiso lokuSebenza:
Xa kuqwalaselwa ukukhutshwa kwetyuwa emanzini olwandle okanye ukubuyisela umva itekhnoloji ye-osmosis membrane, kukho izinto ezininzi eziza kudlala. Ukukhetha ubukhulu becala kuxhomekeke kwiimfuno ezithile zesicelo.
Iinwebu zokukhupha ityuwa emanzini olwandle zigqwesa kwindawo ezinetyuwa eninzi kwaye ziyaxhathisa ekungcoleni. Banikezela ngemilinganiselo egqwesileyo yokulahlwa kwetyuwa, ukuqinisekisa ukuveliswa kwamanzi acocekileyo kunye nomxholo wetyuwa ophantsi. Oku kwenza ukuba inwebu zokukhupha ityuwa emanzini olwandle zibe zilungele iindawo eziselunxwemeni ezijongene nokunqongophala okukhulu kwamanzi, apho amanzi olwandle angowona mthombo wamanzi uphambili.
