Ubucwepheshe be-Membrane busezingeni eliphezulu lokuphathwa kwamanzi esimanje, buletha izixazululo eziphumelelayo zokuhlanzwa kwamanzi ezimbonini ezahlukahlukene. Phakathi kobuchwepheshe obunjalo, ama-membrane e-reverse osmosis (RO) nama-membrane e-nanofiltration (NF) agqama ngamandla awo okususa izinto ezingcolisa amanzi ngokukhetha nokuthuthukisa ikhwalithi yamanzi. Ukuqonda izindima namakhono ama-membrane e-RO kanye ne-NF kubalulekile kumabhizinisi afuna izindlela zokuphathwa kwamanzi ezingathenjwa futhi ezisimeme. Lawa ma-membrane anikela kakhulu ekuvikelweni kwemvelo, ekuthuthukisweni kwezinqubo zezimboni, nasekunikezeni amanzi okuphuza aphephile.

Ama-membrane e-reverse osmosis ayaziwa kakhulu ngokunemba kwawo okungavamile kokuhlunga, okuvumela ukususwa kwezinto ezingcolile ezincane kakhulu, usawoti, namajenjiniyeni. Ama-membrane e-nanofiltration, ngakolunye uhlangothi, anezici ezihlukile ezivumela ukuhlunga izinhlayiya ezithile ngenkathi egcina amaminerali anenzuzo, okwenza kube ukukhetha okuguquguqukayo kwezicelo zokwelashwa ezithile. Ngokuhlanganyela, ama-membrane e-RO kanye ne-NF enza umgogodla wezinhlelo eziphambili zokwelashwa kwamanzi ezihlangabezana namazinga aphezulu kakhulu kanye nezimfuneko zomthetho.

Ukuqina kwezi zihluzo kudlula ukuhlanzwa. Zisekela ukuphathwa kwamanzi okuzinzile ngokunciphisa inkunkuma nokusetshenziswa kwamandla uma kuqhathaniswa nezindlela zokwelapha ezijwayelekile. Njengoba izimboni zikhula zibeka phambili isibopho semvelo, ukwamukelwa kobuchwepheshe bezihluzo ezifana ne-RO ne-NF kuyoba yinto ebalulekile. Izinkampani ezifana ne-Haidi Environment (Tianjin) CO., LTD zisebenzisa lobu buchwepheshe ukuletha izixazululo zokuphathwa kwamanzi ezisezingeni eliphezulu ezihlanganisa ukusebenza kahle nokunakekelwa kwemvelo.

Ngezicelo zazo ezikhulayo emikhakheni efana neyezimithi, ukudla neziphuzo, ukukhiqiza ugesi, kanye nokuhlinzekwa kwamanzi emadolobheni, ama-membrane e-RO kanye ne-NF aqhubeka nokuvela ekusebenzeni nasekuqinekeni kwawo. Ukuhlanganiswa kwezinto ezithuthukisiwe namasu okukhiqiza kuthuthukisa ukumelana kwawo nokungcola nokubola kwamakhemikhali, ngaleyo ndlela kwandisa impilo yokusebenza nokunciphisa izindleko zokugcinwa. Lesi sihloko sihluza izindlela, izinzuzo, kanye nezicelo zamamembrane e-RO kanye ne-NF ukuze sinikeze ukuqonda okuphelele kumabhizinisi acatshangelwa ubuchwepheshe.

Ngokuhlola umehluko nokukhetha ubuchwepheshe obufanele be-membrane, izinhlangano zingathuthukisa izinqubo zazo zokwelashwa kwamanzi ukuze zizuze kakhulu kwezomnotho nezemvelo. Izigaba ezilandelayo zihlakaza kabanzi ezisekelweni ze-reverse osmosis nama-nanofiltration membranes, zinikeza imininingwane ngezimiso zazo zokusebenza nokusetshenziswa okusebenzayo.

Ama-Reverse osmosis membranes asebenza ngokufaka ingcindezi ukuze anqobe ingcindezi ye-osmotic, aphoqe amanzi ngama-semipermeable membrane avimba izinto eziyisidididi, izinto eziphilayo, nezinye izinto ezingcolile. Le nqubo iphumelela amanzi ahlanzeke kakhulu afanele izinhlobonhlobo eziningi zokusebenzisa ezimbonini neziphuzo. Ama-RO membranes ayahlukaniswa ngokwakhiwa kwawo okuyiminyana, ngokuvamile cishe u-0.0001 microns, okwenza akwazi ukususa kufika ku-99% wamatshe angenamkhawulo nezingcolile.

Inzuzo eyinhloko yamalungu e-RO ikhono lawo eliphakeme lokuhlunga, elenza afaneleke kakhulu ekuhlanzeni amanzi olwandle namanzi anosawoti, kanye nasekususeni izinsimbi ezisindayo, amagciwane, namagciwane. Izimboni ezisebenzisa amanzi ahlanzeke kakhulu, njengokukhiqiza ama-semiconductor nemithi, zizuza kakhulu ubuchwepheshe be-RO. Ngaphezu kwalokho, amalungu e-RO anikela ezinhlelweni zokusebenzisa kabusha amanzi ngokuvumela ukwelashwa kwamanzi angcolile ukuze ahlangane nezindinganiso eziqinile zokukhipha noma zokusebenzisa kabusha.

Ngokusebenza, izinhlelo ze-RO zidinga ukwelashwa kwangaphambili ukuvikela ama-membranes ekungcoleni okubangelwa izinhlayiya nokukhula kwezinto eziphilayo, nokwelashwa kwangemuva ukulungisa amakhemikhali emanzini njengoba kudingeka. Ngaphandle kwezidingo lezi, intuthuko ezintweni ezisetshenziswa kuma-membranes kanye nokwakhiwa kwezinhlelo kuthuthukise ukusebenza kahle kwamandla futhi kunciphise izindleko zokusebenza. I-Haidi Environment (Tianjin) CO., LTD ihlinzeka ngama-membranes e-RO asezingeni eliphezulu nezixazululo ezihlanganisiwe ezigcizelela ukuqina nokusebenza, kusiza amaklayenti ukuthi athole ikhwalithi yamanzi engaguquki.

Ngaphezu kwalokho, ubuchwepheshe be-RO membrane busekela ukusimama kwemvelo ngokunciphisa isidingo sezithako zamakhemikhali ekwelashweni kwamanzi nokunciphisa ukukhishwa kwemfucumfucu. Ngokuqhubeka nokuqamba okusha, izinkampani zingakwazi ukwenza ngezifiso izinhlelo ze-RO ezidingweni ezithile zezimboni, zilinganisela amazinga obumsulwa nokusebenza kahle kokusebenza. Lokhu kuvumelana kwenza ama-membrane e-reverse osmosis abe yisisekelo samasu esimanje okwelashwa kwamanzi.

Kwabezindaba abafuna ulwazi olunembile ngemikhiqizo nezixazululo ezenziwe ngokwezifiso ku-reverse osmosis, ukuvakashela i-Imikhiqizoikhasi linikeza isibuyekezo esiphelele sobuchwepheshe bamalensi atholakalayo namakhemikhali okwelashwa.

Ama-membrane e-Nanofiltration ahlala endaweni yokuhlunga phakathi kwe-ultrafiltration ne-reverse osmosis, anobukhulu bemiphetho ovame ukuba cishe obungu-0.001 microns. Ahloselwe ukususa ngokukhetha ama-divalent nama-monovalent ions amakhulu, ama-organic molecules, kanye nezifo ezithile ngenkathi evumela ama-monovalent ions amancane namaminerali anenzuzo ukuthi adlule. Lokhu kuhlunga okukhethekile kubangela amanzi agcina okuthile okuqukethwe amaminerali, okungaba yinzuzo ezicelo ezidinga amazinga amaminerali alinganayo.

Izici eziyinhloko zamamembrane e-NF zihlanganisa izingcindezi eziphansi zokusebenza uma kuqhathaniswa namamembrane e-RO namazinga aphezulu okudlula, okuhumusha kusho ukonga amandla nokwanda kokudlula. I-Nanofiltration isetshenziswa kabanzi ekuthambiseni amanzi aqinile, ekususeni izinto zemvelo zemvelo, nasekwelapheni amanzi amdaka ukuze asetshenziswe kabusha ezolimo noma ezimbonini. Amamembrane futhi anciphisa ngempumelelo umbala, ukungcola, nezingcolisi ezithile njengemithi yokubulala izinambuzane namagciwane.

Indlela ye-nanofiltration ihilela ukukhishwa ngosayizi nokuhlukaniswa okusekelwe emandleni, okuvumela amamembrane e-NF ukuthi ahlasele izingcolisi ezithile ngenkathi egcina ukunambitheka kwamanzi nokuqukethwe kwezakhamzimba. Lokhu kwenza amamembrane e-NF afaneleke kakhulu ekucubunguleni ukudla neziphuzo, ekwelapheni amanzi amdaka ezindwangu, nasekwelapheni amanzi kamasipala. Ukuguquguquka kwawo nokusebenza kwawo kubeka i-nanofiltration njengenye indlela engabizi noma eyengeziwe ezinhlelweni ze-reverse osmosis.

I-Haidi Environment (Tianjin) CO., LTD ihlanganisa izihlungi zamanzi ze-nanofiltration ezithuthukisiwe ezinhlelweni zayo zokwelapha amanzi, inikeza amaklayenti izixazululo ezintsha ezibhekana nezinselelo ezahlukahlukene zokuhlanzwa. Ukugxila kwenkampani ocwaningweni nasekuthuthukisweni kuqinisekisa ukuthi izihlungi zayo ze-NF zihlinzeka ngokumelana nokungcola okuthuthukisiwe nokuqina, kunciphisa izidingo zokugcinwa kwezindleko zokusebenza.

Ukuze uthole imininingwane eyengeziwe ngokusetshenziswa kwezihlungi zamanzi ze-nanofiltration nokuhlola imikhiqizo enikezwayo, Imikhiqizo1ikhasi linikeza ulwazi oluningiliziwe ngobuchwepheshe obusha bukaHaidi Environment bokulawula amanzi.

Izihluzo ze-Reverse osmosis (RO) ne-nanofiltration (NF) zihlukile ngokuyisisekelo ekunembeni kokuhlunga, emingceleni yokusebenza, nasekuphathweni kwezicelo. Izihluzo ze-RO zihlinzeka ngezinga eliphezulu kakhulu lokukhipha usawoti oncibilikile, izinhlayiya, namagciwane, zifinyelele ukukhipha usawoti nokuhlanza cishe ngokuphelele. Izihluzo ze-NF zinikeza amazinga okukhipha aphakathi, kodwa zikhethekile ekuhlukaniseni okukhethiwe, zigcina amaminerali abalulekile ngenkathi kukhishwa izinto ezinkulu ezingcolisa amanzi.

Ubungako bezinhlayiya buhlukanisa phakathi kwezimbili: izihlungi ze-RO zihlunga izinhlayiya ezifinyelela ku-0.0001 microns, kanti izihlungi ze-NF zihlunga izinhlayiya ezinkulu cishe izikhathi eziyishumi. Leli hluka lithinta ukukhethwa kwesihlungi ngokusekelwe ekwakhekeni kwamanzi nezinjongo zokwelashwa. Ngokwesibonelo, i-RO ikhethwa ukukhipha usawoti emanzini olwandle nokukhiqiza amanzi ahlanzeke kakhulu, kanti i-NF ilungele ukuthambisa nokuhlanzwa okuyingxenye lapho ukugcinwa kwamaminerali kufiseleka.

Ngokusebenza, izihlungi ze-NF zidinga ingcindezi ephansi kanye nokufakwa kwamandla kancane kunezihlungi ze-RO, okunikeza ukonga izindleko ezimeni ezithile. Kodwa-ke, izinhlelo ze-RO ngokuvamile zihlanganisa izindleko eziphakeme zokuqala nokugcinwa ngenxa yezidingo eziqinile zokwelashwa kwangaphambili kanye nokuzwela kwezihlungi. Ngaphezu kwalokho, izihlungi ze-NF zivame ukuba namazinga aphezulu okudlula, okuholela ekwandeni kokudlula nokusebenza kahle kwezicelo ezihambisanayo.

Lapho kuhlolwa ukungcola kwamagobolondo (membrane fouling) nezinqubo zokuhlanza, amagobolondo e-NF avame ukubonisa ukubekezelelana okukhulu nokungcola okuvela emzimbeni, nakuba zombili ubuchwepheshe zizuza ekwakhiweni okuhle kakhulu kohlelo kanye namasu okugcinwa. Izinto ezithinta ezomnotho nezokusing environment, okubandakanya amazinga okubuyisa amanzi nokuphathwa kukadoti osawolintshi, zithonya kakhulu ukukhethwa kwamagobolondo e-RO noma e-NF.

Ukuze uthole ukuqonda okuphelele kwezixazululo zokwelapha amanzi nokuthi ungakhetha kanjani ubuchwepheshe bamagobolondo obufanele kakhulu, ukubonisana ne-Mayelana Nathi ikhasi linikeza umongo obalulekile ngemikhuba emihle kakhulu embonini kanye nobuchwepheshe bukaHaidi Environment kule ndawo.

Ukukhetha ubuchwepheshe obufanele be-membrane kubalulekile ukuze kufezekiswe imiphumela engcono kakhulu yokwelashwa kwamanzi eyenzelwe izidingo ezithile zezimboni noma zikamasipala. Izinto ezifana nekhwalithi yamanzi okudla, ubumsulwa bamanzi obufunwayo, izindleko zokusebenza, nomthelela kwimvelo kufanele kuhloliswe ngokucophelela. Ama-membrane e-RO avame ukukhethwa ezinhlelweni ezidinga amazinga aphezulu kakhulu obumsulwa, kanti ama-membrane e-NF athandwa kakhulu ezinqubweni ezizuzwa ngokuhlunga okukhethekile nokugcinwa kwemaminerali.

I-Haidi Environment (Tianjin) CO., LTD iyazihlukanisa ngokunikeza uhla olubanzi lwezobuchwepheshe bemembrane kuhlanganiswe nokubonisana kwezobuchwepheshe kanye nokuhlanganiswa kwezinhlelo okwenziwe ngokwezifiso. Umnqamulajuqu wabo uhleleke ezindaweni ezithuthukisiwe zemembrane, imiklamo yesistimu eyinoveli, kanye nokuzibophezela ekusimameni, ukusiza amaklayenti anciphise ukusetshenziswa kwamandla nezindleko zokusebenza ngenkathi behlangabezana nezindinganiso eziqinile zokuhlanzeka kwamanzi.

Indlela ephelele yenkampani ihlanganisa ukusekela amaklayenti kuyo yonke imijikelezo yephrojekthi — kusukela ekuhlolweni kokuqala kwekhwalithi yamanzi nokukhethwa kwamalensi kuya ekufakweni, ukuqapha, nokugcinwa.
