Eshintsha njalo embonini yokwelapha amanzi, ubuchwepheshe bemibhonqwana njengama-reverse osmosis (RO) kanye ne-nanofiltration (NF) budlala indima ebalulekile ekukhiqizeni amanzi ahlanzekile asezingeni eliphezulu. Naphezu kokusetshenziswa kwawo kabanzi, le mibhonqwana ivame ukubhekana nezinselelo ezifana nokungcola, ukubola kwe-chlorine, nokukhetha okulinganiselwe okunganciphisa ukusebenza kwawo nokuphila kwawo. Ukubhekana nalezi zinselelo kubalulekile ezimbonini ezisebenzisa izixazululo zemibhonqwana ekuhlanzeni amanzi, ekwelapheni amanzi amdaka, nasezinhlelweni zamanzi ezicubungulayo. I-Haidi Environment (Tianjin) CO., LTD, umholi kwezobuchwepheshe bemibhonqwana ezintsha, yenze izinyathelo ezinkulu ekunqobeni le mikhawulo ngokuthuthukisa ama-reverse osmosis membranes athuthukisiwe kanye nama-nanofiltration membranes. Lesi sihloko sihluza ukuthi ama-membranes amasha e-Haidi ashintsha kanjani izinqubo zokwelapha amanzi ngokuhlala isikhathi eside nokusebenza kahle.

Ukuqhubeka kokubaluleka kobuchwepheshe be-membrane kuyaqhubeka nokukhula njengoba ukushoda kwamanzi emhlabeni kanye nezinkinga zokungcola ziba zimbi kakhulu. Ama-membrane emidala avame ukuhlupheka ngokubola okusheshayo lapho echayeke kuma-oxidants afana ne-chlorine, okudinga ukushintshwa njalo nokwandisa izindleko zokusebenza. Ngaphezu kwalokho, ukufeza ukusebenza kahle kokuhlunga nge-nanofiltration membranes kudinga ukulinganisela phakathi kokwenqatshwa kwe-solute kanye ne-permeability, okungaba nzima ngezinto ezivamile. Ukuzibophezela kwe-Haidi Environment ocwaningweni nasekuthuthukisweni kuyenza ikwazi ukuhlinzeka ngama-membrane agcina amazinga aphezulu okwenqatshwa ngenkathi kuthuthukiswa ukumelana ne-chlorine nokuvimbela ukungcola. Le nhlanganisela yezici ibeka ama-membrane abo njengesinqumo esingcono kakhulu ezindaweni zezimboni ezidingayo.

Ama-membrane e-reverse osmosis asebenza ngokufaka ingcindezi ukuze aphoqe amanzi ku-membrane evumela ukudlula kwezinye izinto kodwa ingavumeli ezinye, okususa ngempumelelo izinhlaka ezincibilikile, izinto eziphilayo, nezinye izinto ezingcolile. Le nqubo isetshenziswa kabanzi ekukhipheni usawoti emanzini olwandle, ekuphindiseni ukusetshenziswa kwamanzi angcolile, nasekukhiqizeni amanzi ahlanzeke kakhulu. I-Nanofiltration, ngakolunye uhlangothi, ihlose izinto ezine-molecular weight enkulu kancane nama-divalent ions, okuyenza ilungele ukuthambisa amanzi nokususa izinto ezithile ezifana ne-pesticides nezinto eziphilayo zemvelo.

Zombili izinhlobo zamaseli zisekelwa izinto zamapholiyima ezinamandla okukhetha ukungena. Amaseli e-RO ngokuvamile anezimbobo ezincane, anikeza amazinga aphezulu okukhipha usawoti avame ukudlula u-99%. Amaseli e-nanofiltration avumela amazinga aphezulu okugeleza kwamanzi kodwa ngokusebenza okuncane kokukhipha. Uhlobo ngalunye lweseli lwenziwa ngezindawo ezihlukahlukene zokusebenza, kusukela ezitshalweni zokuhlanza amanzi omphakathi kuya ezimbonini zamaphilisi kanye nokucubungula ukudla.

Ubuchwepheshe bukaHaidi buhlanganisa ukuthuthukisa lezi zindlela zamagobolondo ngokwenza ngokwezifiso amakhemikhali namandla amagobolondo. Lokhu kuthuthukisa ukusebenza kahle kokuhlukanisa ngenkathi kuqinisekiswa ukuthi amagobolondo ayakwazi ukubekezelela izimo ezinzima zokusebenza, okuhlanganisa i-pH eguquguqukayo, ukushintsha kwezinga lokushisa, nokuchayeka kumagciwane afana ne-chlorine. Ngenxa yalokho, amakhasimende azobona ukuncipha kwesikhathi sokungasebenzi kanye nezindleko eziphansi zokugcinwa.

I-Haidi Environment (Tianjin) CO., LTD ihamba phambili ekwakhiweni kobuchwepheshe bamalaphu, igxile ekuthuthukiseni amalaphu e-reverse osmosis angamelana ne-chlorine kanye namalaphu e-nanofiltration athuthukile. Izinto zabo zamalaphu ezibhalisiwe zihlanganisa amafomula amapholima athuthukisiwe kanye nezingubo zangaphezulu ezintsha ukuze zimelane nomonakalo obangelwa yi-oxidative nokungcola.

Ukuphumelela okukhulu kuma-membrane eHaidi ungqimba lwe-polyamide olumelana ne-chlorine, oluvimbela ukubola futhi lwandisa kakhulu impilo ye-membrane uma kuqhathaniswa nama-membrane e-RO ajwayelekile. Lobu buchwepheshe buvumela ama-membrane ukuthi abekezelele amazinga aphezulu e-chlorine ngaphandle kokulahlekelwa ukusebenza, okwenza abe alungele amanzi okuphakelayo alashwe ngaphambili aqukethe izibulala-magciwane ezisele.

Ngaphezu kwalokho, ama-nanofiltration membranes akwa-Haidi anikeza ukusatshalaliswa okuhle kakhulu kwama-pore size kanye nezici zokushaja ubuso, okuvumela ukususwa okukhethiwe kwezinto ezingcolisa amanzi ngenkathi kugcinwa ukungena okuphezulu. Ama-membranes abo abonisa ukuzinza okuphawulekayo kwe-flux kanye namazinga okwenqatshwa angaguquki phakathi nezikhathi ezide zokusebenza.

Lezi zinguquko zobuchwepheshe ziholela kuma-membranes ahlinzeka ngekhwalithi yamanzi ephakeme, ukwethembeka kokusebenza, kanye nokonga izindleko. I-Haidi Environment iqhubeka nokutshala imali ocwaningweni futhi ibambisane eduze nabalingani bemboni ukuze kuthuthukiswe ukusebenza kwe-membrane futhi kuthuthukiswe izixazululo ezilandelayo zokwelashwa kwamanzi.

Ukungcola kwe-membrane nokubola okubangelwa yi-chlorine yizinto ezimbili ezinkulu ezikhawulelisa impilo nokusebenza kahle kwe-membrane ezinhlelweni zokwelapha amanzi. Ama-membrane e-Haidi akwazi ukumelana ne-chlorine axazulula kahle lezi zinkinga ngokufaka izinto eziqinile ze-polymeric ezilondoloza ubuqotho besakhiwo namakhono okuhlunga naphezu kokuchayeka isikhathi eside ku-chlorine.

Lokhu kumelana ne-chlorine kunciphisa isidingo sokuhlanza amakhemikhali okubizayo nokushintsha i-membrane, okuholela ezindlekweni eziphansi zokusebenza kanye nokuyeka ukusebenza kohlelo. Ngaphezu kwalokho, ukumelana okuthuthukisiwe nokungcola kunciphisa ukwehla kwe-flux, kugcina amanani aphezulu okugeleza kwe-permeate kanye nekhwalithi yamanzi engaguquki. Izinzuzo zicace kakhulu ezinhlelweni zezimboni lapho ikhwalithi yamanzi okuphakelayo iguquguquka noma iqukethe izinsalela zokubulala amagciwane.

Ama-membrane e-Haidi abonisa namandla amakhulu emishini kanye nokuzinza kwamakhemikhali, okuvumela ukusetshenziswa kwawo ezindaweni ezahlukahlukene kanye namanzi ayinkimbinkimbi. Lokhu kuqina kuhumusha ekuthembekeni kwesikhathi eside kanye nokuzethemba komsebenzisi, okuhlukanisa imikhiqizo ye-Haidi kweminye imikhiqizo ye-membrane emakethe.

Uma kuqhathaniswa nemikhiqizo ye-reverse osmosis ne-nanofiltration yakudala, imikhiqizo ye-Haidi ethuthukisiwe ibonisa ukuthuthuka okubonakalayo ezindabeni eziningana ezibalulekile zokusebenza. Ukumelana ne-chlorine kuyinzuzo evelele, okuvumela izinketho eziningi zokwelashwa kwangaphambili futhi kunciphise ubungozi bokwehluleka kwe-membrane. Imikhiqizo ye-membrane yakudala ivame ukudinga ukususwa kwe-chlorine okuqine kakhulu kwamanzi okuphakelayo, okungangeza ubunzima nezindleko.

Ngokuya ngokusebenza kokuhlukanisa, amagobolondo kaHaidi agcina amazinga aphezulu okuphika amakhemikhali aphelele ancibilikile, izinto eziphilayo, nezifo, aqinisekisa ikhwalithi yamanzi ephakeme. Ukungena kwawo okuthuthukisiwe kunciphisa ukusetshenziswa kwamandla ngokuvumela amazinga aphezulu okubuyisa amanzi nokunciphisa izidingo zengcindezi yesistimu. Lezi zici zibeka isandla ekuthuthukiseni ukusimama nokusebenza kahle kokusebenza.

Ngaphezu kwalokho, ukumelana nokungcola kwamagobolondo (membranes) kunciphisa imvamisa yokuhlanza ngamakhemikhali futhi kwandisa impilo yesevisi yamagobolondo, okunikeza izinzuzo ezibalulekile kwezomnotho nezemvelo. Amagobolondo e-Haidi Environment enziwe ukuze ahlangabezane nezidingo eziqinile zezitshalo zesimanje zokwelapha amanzi, abeka amazinga amasha embonini.

Imembrane zeHaidi zitholakala ezindaweni eziningi ezidinga ubuchwepheshe bokwelapha amanzi obuqinile. Ekwelapheni amanzi emiphakathini, imembrane zazo zokuphendukela emuva zenza ukukhiqizwa kwamanzi okuphuza aphephile kanye nokusetshenziswa kabusha kwamanzi angcolile. Izimboni ezifana nokukhiqiza amakhemikhali, imithi, kanye nokudla & iziphuzo zisebenzisa imembrane zeHaidi zokuhlunga ezincane ukuze ziqede ukungcola okuqondile nokuhlanza amanzi okusebenza.

Izitshalo zamandla nezinhlelo zokupholisa amanzi zithola inzuzo kumembrane zeHaidi eziphikisana ne-chlorine ngokunciphisa ukungcola kwe-biofouling nokwakheka, okuholela ekuthuthukisweni kokushintshaniswa kokushisa kanye nezindleko zokmaintenance eziphansi. Izinhlelo zokunisela ezisemhlabeni nazo zisebenzisa lezi membran ukuze zinikeze amanzi aphezulu anesimo esihle esisekela impilo yezitshalo ngenkathi kuncishiswa ubungozi bokukhula kwe-salinity emhlabathini.

Ukuzinikezela kwe-Haidi Environment ekusunguleni imikhiqizo nokwenza ngokwezifiso kubavumela ukuthi benze izixazululo zamamembrane ngokuvumelana nezinselelo ezithile zamanzi zamakhasimende nezimfuneko zomthetho. Le ndlela egxile kumakhasimende yandisa ukusebenza okuhlukahlukene nokusebenza kweqoqo labo lamamembrane.

Sibheke phambili, i-Haidi Environment izibophezele ekuthuthukiseni ubuchwepheshe bamamembrane ngokusebenzisa imizamo eqhubekayo yocwaningo nentuthuko. Izindawo abazigxile kuzo zihlanganisa ukuthuthukisa ukukhetha kwamamembrane, ukuthuthukisa izendlalelo ezivimbela ukungcola, nokuhlanganisa izinhlelo zokuqapha ezihlakaniphile ukuze kutholwe ukusebenza ngesikhathi sangempela.

Amaqembu e-R&D kaHaidi ahlanganyela nezikhungo zemfundo nabalingani bemboni ukuze ahlolisise amapholima amasha namasu okwakha ama-membrane. Imizamo le ihlose ukuthuthukisa ama-membrane angagcini nje ngokuhlangabezana nezidingo eziguqukayo zokwelashwa kwamanzi kodwa futhi asekele izinhloso zokusimama ngokunciphisa ukusetshenziswa kwamandla nokusetshenziswa kwamakhemikhali.

Njengoba indawo yomhlaba wonke yokwelashwa kwamanzi ishintshela kumamodeli omnotho oyindilinga kanye namazinga angqongqo emvelo, iHaidi Environment ilungele ukuhola imboni ngemikhiqizo ye-membrane entsha nezixazululo zokuphathwa kwamanzi ezihlanganisiwe. Ukuzibophezela kwabo kwekhwalithi, ukwethembeka, nokunakekelwa kwemvelo kuqinisekisa ukuthi iHaidi ihlala iyisihambeli esithembekile kumakhasimende emhlabeni wonke.
