Izixazululo ezijwayelekile ezingama-25 zenkinga yobuchwepheshe be-osmosis membrane (Ingxenye 3)

13. Kuyini ukungcola kwezinhlayiyana kanye ne-colloid? Indlela yokulinganisa?

Uma ukungcola kwezinhlayiyana kanye ne-colloid kwenzeka kumasistimu e-osmosis ehlanekezelwe noma amasistimu e-nanofiltration, kungase kube nomthelela omkhulu ekukhiqizweni kwamanzi kolwelwesi futhi ngezinye izikhathi kunciphise izinga lokukhipha usawoti emanzini. Izimpawu zakuqala zokungcoliswa kwe-colloidal ukwanda komehluko wengcindezi yesistimu, futhi imithombo yezinhlayiya noma ama-colloid emthonjeni wamanzi ongenisa ulwelwesi iyahlukahluka indawo ngezindawo, ngokuvamile okuhlanganisa amagciwane, udaka, i-silicon ye-colloidal, imikhiqizo ye-iron corrosion, njll. Izidakamizwa ezisetshenziswa engxenyeni yokwelashwa kwangaphambili, njenge-polyanium kanye ne-ferric chlorication noma i-polylic chloride ayikwazi ukubangela futhi i-polylic chloride ikhishwe ngempumelelo kuthangi lokucacisa noma isihlungi esiphakathi. Ngaphezu kwalokho, i-cationic polymeric dielectrics ingaphinde isabele nge-anionic scale inhibitors, futhi imvula yayo ingangcolisa izingxenye ze-membrane. I-SDI15 isetshenziselwa ukuhlola ukuthambekela kokungcoliswa okunjalo noma ukwelashwa kwangaphambili emanzini. Sicela ubheke isingeniso esinemininingwane ezahlukweni ezifanele.

14. Kungakanani ukuvala okukhulu okuvunyelwe ngaphandle kokuguquguquka kwesistimu?

Uma uhlelo lusebenzisa ama-scale inhibitors, lapho izinga lokushisa lamanzi liphakathi kuka-20-38 ℃, kuthatha cishe amahora angu-4; Cishe amahora angu-8 ngaphansi kuka-20 ℃; Uma isistimu ingasebenzisi ama-scale inhibitors, kuzothatha cishe usuku olungu-1.

15. Kungancishiswa kanjani ukusetshenziswa kwamandla kwesistimu ye-membrane?

Izakhi ze-membrane zokusebenzisa amandla aphansi zanele, kodwa kufanele kuqashelwe ukuthi izinga labo lokukhipha usawoti emanzini liphansi kancane kunalelo lezinto ezijwayelekile zolwelwesi.

Ingadlula ngokukhululekile kulwelwesi lwe-microfiltration, olusetshenziselwa ukususa amagciwane, ama-micro flocs, noma okuqinile okumisiwe okuphelele (TSS). Ingcindezi evamile ezinhlangothini zombili ze-membrane yi-1-3 bar

16.Ingabe isistimu yamanzi ahlanzekile e-reverse osmosis ingase iqale futhi ime?

Uhlelo lwe-membrane luklanyelwe ngokusekelwe ekusebenzeni okuqhubekayo, kodwa ekusebenzeni kwangempela, kuzohlala kukhona imvamisa ethile yokuqalisa nokuvala. Lapho uhlelo lwe-membrane luvaliwe, kuyadingeka ukuthi kusetshenziswe amanzi awo akhiqiziwe noma amanzi asele ahlanzwe ngaphambili ukuze kukhishwe umfutho ophansi ukuze kungene amanzi agxilile agxilile aqukethe ama-scale inhibitors avela ezingxenyeni zolwelwesi. Kufanele futhi kuthathwe izinyathelo zokuvimbela ukuvuza kwamanzi ohlelweni kanye nokwethulwa komoya, njengokungathi ingxenye ivuza futhi yome, kungase kubangele ukulahlekelwa okungenakulungiseka kokuguquguquka kokukhiqizwa kwamanzi. Uma ukuvala shaqa kungaphansi kwamahora angama-24, asikho isidingo sokuthatha izinyathelo zokuvimbela ukukhula kwamagciwane. Kodwa uma isikhathi sokuvala shaqa sidlula le mithetho engenhla, uketshezi oluyisivikelo kufanele lusetshenziselwe ukulondolozwa kwesistimu noma ukugudluzwa okunesikhathi kolwelwesi lwesistimu.

17.Unganquma kanjani isiqondiso sokufaka izindandatho zokuvala amanzi anosawoti ezingxenyeni ze-membrane?

Indandatho yokuvala amanzi anosawoti ku-membrane element iyadingeka ukuthi ifakwe ekugcineni kwe-elementi, indawo evulekile ibheke endaweni yokungena. Lapho umkhumbi wokucindezela ugcwele amanzi, ukuvulwa kwawo (umkhawulo we-lip) kuzophinde kuvuleke, kuvale ngokuphelele ukugeleza kwamanzi ohlangothini olusuka ku-membrane element kuya odongeni lwangaphakathi lomkhumbi wokucindezela.

18.Ungayikhipha kanjani i-silicon emanzini?

I-silicon emanzini ikhona ngezindlela ezimbili: i-silicon esebenzayo (i-silicon ye-monomeric) ne-silicon ye-colloidal (i-polysilicon): i-silicon ye-colloidal ayinazo izici zama-ion, kodwa inesilinganiso esikhulu uma kuqhathaniswa. I-silicon ye-Colloidal ingavinjwa izinqubo zokuhlunga zomzimba ezinhle, ezifana ne-osmosis ehlehlayo, futhi okuqukethwe kwamanzi kungancishiswa ngobuchwepheshe bokuhlangana, njengamathangi okucacisa i-coagulation. Kodwa-ke, ubuchwepheshe bokuhlukanisa obuncike ezicini zokushajwa kwe-ion, njengezinhlaka zokushintshana kwe-ion kanye nezinqubo eziqhubekayo ze-electrodeionization (CDI), zinokusebenza okulinganiselwe ekususeni i-silicon ye-colloidal.

Usayizi we-silicon ecushiwe mncane kakhulu kunalowo we-silicon ye-colloidal, ngakho-ke ubuchwepheshe obuningi bokuhlunga obubonakalayo obufana nokucaciswa kwe-coagulation, ukuhlunga, nokuntanta komoya abukwazi ukususa i-silicon ecushiwe. Izinqubo ezingasusa ngempumelelo i-silicon ecushiwe zihlanganisa i-osmosis ehlehlayo, ukushintshaniswa kwe-ion, kanye ne-electrodeionization eqhubekayo.
