Ukushoda kwamanzi kuyanda ngokushesha ukuba kube yinye yezinselelo ezinkulu zomhlaba wekhulu lama-21. Njengoba izibalo zabantu zikhula futhi izinguquko zesimo sezulu ziba zimbi izimo zokumila, isidingo semithombo yamanzi ahlanzekile siyanda. Kulokhu, ubuchwepheshe bokukhipha usawoti emanzini buvela njengesixazululo esibalulekile, siguqule amanzi olwandle namanzi anosawoti abe amanzi okuphuza. Lesi sihloko sihluza ukuthuthuka, izinto ezintsha, kanye neziqondiso zokuzinza zobuchwepheshe bokusebenza kwezitshalo zokukhipha usawoti, sinikeza amabhizinisi ukuqonda okujulile kulo mkhakha wokwelashwa kwamanzi oguqukayo. Siphinde sigqamise indima ye-Haidi Environment (Tianjin) CO., LTD ekuthuthukiseni izixazululo zokwelashwa kwamanzi ukuze kuhlangatshezwane nezidingo zomhlaba ezikhulayo.

Emhlabeni jikelele, abantu abangaphezu kwezibilioni ezimbili bahlala ezindaweni ezibhekene nokushoda kwamanzi okukhulu, kanti ukwanda kwemizi kanye noshintsho lwesimo sezulu kwenza ukushoda kwamanzi kube kubi kakhulu. Izibalo ezivela ezinhlanganweni zamanzi zomhlaba zikhombisa ukuthi ngo-2050, cishe ingxenye yomhlaba wonke ingase ihlale ezindaweni ezinokushoda okuphelele kwamanzi. Le nkinga igqugquzelwa yizimo zemvula ezingalindelekile, ukuphela kwemithombo yamanzi ahlanzekile, kanye nokwanda kwezidingo zamanzi zezimboni nezolimo. Isidingo esiphuthumayo sezixazululo ezisimeme zokuhlinzekwa ngamanzi asikaze sibe sikhulu kangaka. Ukukhipha usawoti emanzini olwandle kuvele njengobuchwepheshe obungasebenza ukunciphisa ingcindezi emithonjeni yamanzi ahlanzekile esetshenziswe kakhulu ngokusebenzisa imithombo eningi yamanzi olwandle.

Nokho, izinselelo ezikhona ngokushoda kwamanzi zidinga izindlela ezihlanganisiwe. Ukukhipha usawoti emanzini kufanele kuhambisane nokonga amanzi, ukuwasebenzisa kabusha, kanye nezinethiwekhi zokusabalalisa ezisebenza kahle. Izindawo zasemadoleni, ikakhulukazi ezifundeni ezinomswakama ophansi, ziya ngokuya ziphendukela ezitshalweni zokukhipha usawoti ukuze kuqinisekiswe ukuhlinzekwa kwamanzi okuqhubekayo. Lesi sifiso esikhulayo siqhuba intuthuko yezobuchwepheshe ehlose ukuthuthukisa ukusebenza kahle kwamandla, ukwehlisa izindleko, kanye nokunciphisa imithelela emvelweni ehambisana nemisebenzi yokukhipha usawoti emanzini.

Ukukhipha usawoti akuyona into entsha; imvelaphi yayo ingalandelelwa emakhulwini eminyaka adlule, nezinye izindlela zokuqala ezazihlanganisa ukudiliza ilanga okulula nezindlela zokubilisa. Nokho, eminyakeni eyikhulu edlule, ubuchwepheshe buye bashintsha kakhulu. Ukuthuthukiswa kobuchwepheshe be-membrane, njengokuhlinzwa ngokuphambene (RO), kwaguqula ukukhipha usawoti kusuka kunqubo edla amandla amaningi kuye kwaba isixazululo esingakhuphuka futhi esisebenza kahle kakhulu. I-RO isebenzisa ama-membrane avumela ukudlula kwezinto ezithile ukususa usawoti nokungcola, yaba yindlela ebusayo ezitshalweni zokukhipha usawoti zesimanje.

Ezinye izindlela zihlanganisa ukufingqa okunezinyathelo eziningi (MSF) kanye nokufingqa okunezikhathi eziningi (MED), ezisebenzisa amandla ashisayo ukukhipha amanzi olwandle. Ukuqanjwa okusha ekukhipheni amanzi olwandle okusebenzisa ubushushu kuholele ezinhlelweni ezihlanganisiwe ezihlanganisa izinqubo ze-RO nezobushushu, okwenza ukusetshenziswa kwamandla kube kahle. Ukuthuthukiswa kobuchwepheshe bokukhipha amanzi olwandle kubonisa ukufuna okuqhubekayo kokulinganisa ukusebenza kahle, ukonga izindleko, kanye nokusimama kwemvelo.

Iminyaka yakamuva ibone izinto ezintsha ezimangalisayo kubuchwepheshe bokukhipha usawoti olwandle obubhekana nemikhawulo yangaphambili. Enye yalezi zithuthukisiwe ukukhipha usawoti olwandle olujulile, olusebenzisa izendlalelo ezibandayo, ezijulile zolwandle ukuthuthukisa ukusebenza kahle kwe-thermal nokunciphisa umthelela wemvelo. Lezi zinhlelo zingahlanganiswa namapulatifomu angaphandle kolwandle noma amadolobha aseceleni kolwandle ukuhlinzeka ngamanzi ahlanzekile ngqo kubathengi abadolobha nezimboni.

Ukusetshenziswa kahle kwamandla kuhlala kuyinto ebalulekile, njengoba ukukhipha usawoti emanzini ngokwesiko kudinga amandla amaningi. Izimboni zesimanje zisebenzisa amadivayisi okonga amandla abuyisa amandla omfutho ngaphakathi kwenqubo ye-RO, kunciphisa kakhulu ukusetshenziswa kukagesi. Ngaphezu kwalokho, ukuhlanganiswa kwemithombo yamandla avuselelekayo njengamandla elanga nawomoya ezikhungweni zokukhipha usawoti emanzini kuletha indlela ethembisayo yokuphatha ngendlela esimeme. Izinkampani ezifana ne-Haidi Environment (Tianjin) CO., LTD ziqeqeshelwe amakhemikhali nezixazululo zokwelapha amanzi ezinganaki umonakalo emvelweni ezithuthukisa ukusebenza kwamalaphu (membranes) nokusebenza kahle kwezimboni, zisekele le ngungu yokuya emvelweni eluhlaza.

Nakuba ukukhipha usawoti emanzini kunikeza isixazululo esibalulekile sokuntuleka kwamanzi, kuphinde kubeke nezinselele zemvelo. Izinqubo zendabuko zokukhipha usawoti zingaholela ekukhishweni kukasawoti, okuthi uma kungaphathwa kahle, kuthinte kabi imvelo yasolwandle ngenxa yosawoti omningi nokuqukethwe amakhemikhali. Ukusetshenziswa kukagesi okuningi ezitshalweni zokukhipha usawoti kuvame ukubangela ukungcola okukhulu komoya-mpilo ngaphandle kokuthi kusetshenziswe amandla avuselelekayo.

Amasuphu esimanjalo ahlosile ukunciphisa lezi zinkathazo ngokuthuthukisa amasu okuphatha amanzi anosawoti, njengokunciphisa amanzi anosawoti, ukuwasebenzisa ngokunenzuzo, kanye nezi-sistimu zokukhipha amanzi angamanzi (ZLD). Ukuqhubeka kwezibuyekezo zamakhemikhali, okubandakanya lawo athuthukiswe yi-Haidi Environment (Tianjin) CO., LTD, kusiza ukuthuthukisa impilo yamalaphu okuhlanzwa amanzi nokunciphisa udoti wamakhemikhali. Lezi zintuthuko zibeka isandla ekusebenzeni okuhle kwezemvelo kokuhlanjululwa kwamanzi, okwenza kube lula izixazululo ezisimeme zokwelapha amanzi ezihambisana nezinjongo zemvelo zomhlaba wonke.

Imakethe yokukhipha usawoti olwandle ibona ukukhula okuqinile okuqhutshwa isidingo esivela kuhulumeni, omkhandlu kamasipala, nezimboni emhlabeni wonke. Abahlinzeki bezobuchwepheshe abahamba phambili nabathengisi bamachemikhali balokhu benza imikhiqizo yabo ibe mihle ukuze bahlangabezane nezidingo ezahlukene zezifunda. Izinkampani ezibalulekile zihlanganisa izinkampani zamazwe omhlaba ezikhethekile kubuchwepheshe be-membrane, izinhlelo zokonga amandla, kanye nezixazululo zokwelashwa kwamachemikhali.

I-Haidi Environment (Tianjin) CO., LTD igqama njengomdlali onokuncintisana ohlinzeka ngamachemikhali athuthukisiwe okuphatha amanzi enzelwe izinhlelo ze-reverse osmosis namanzi okupholisa. Imikhiqizo yabo emisha ithuthukisa ukusebenza kahle kwezitshalo zokukhipha usawoti olwandle kanye nokuhambisana nemvelo, ilethe inani kumakhasimende. Amathuba emakethe akhulayo agcizelelwa ukwanda kokutshalwa kwezimali kukahulumeni kanye nokubambisana phakathi kukahulumeni nezinkampani ezizimele okugxile ekuthuthukisweni kwezinsiza zamanzi ezisimeme.

Ngaphandle kokuqhubeka kobuchwepheshe, ukukhipha usawoti olwandle lubhekene nezinselelo zokusebenza ezifana nezindleko eziphezulu zokuqala, izidingo zamandla, nezikhalazo zemvelo. Ukwehluleka kwamaphrojekthi adlule kuvame ukubangelwa ukuhlela okunganele noma ukuntuleka kokuhlanganiswa nezinqubomgomo zokuphatha amanzi zasendaweni. Ukubhekana nalezi zinkinga kudinga izindlela ezihlangene ezihlanganisa ubuchwepheshe, umthetho, nokubandakanyeka komphakathi.

Ikhethelo lokukhipha usawoti emanzini lincike ekuthuthukisweni okuqhubekayo, ikakhulukazi emandleni okonga amandla nasekuvikelweni kwemvelo. Izinto ezintsha ezivelayo zihlanganisa ukusetshenziswa kobuhlakani bokwenziwa ukuze kuthuthukiswe izitshalo kanye nokuthuthukiswa kwamagobolondo (membranes) ashibhile, asebenza kahle kakhulu. Izinkampani ezifana ne-Haidi Environment (Tianjin) CO., LTD zihamba phambili, zinikeza izixazululo zamakhemikhali eziklanyelwe ukuthuthukisa ukwethembeka kwezitshalo nokusimama. Ukwamukela lezi zinto ezintsha kubalulekile ekwandiseni ukukhipha usawoti emanzini njengomthombo wamanzi oqhubekayo emhlabeni wonke.

Ubuchwepheshe bokusebenza kwezitshalo zokukhipha usawoti emanzini bunikeza indlela ebalulekile yokubhekana nenkinga yokushoda kwamanzi emhlabeni wonke ekhula njalo. Ngokuziphendukela kwemvelo komlando kanye nokuqanjwa kwezinto ezintsha zesimanje, ukukhipha usawoti emanzini kuye kwaba ngcono kakhulu futhi kwaba nemvelo. Njengoba isidingo sikhula, izindlela ezisimeme ezisekelwa izixazululo zamakhemikhali ezithuthukile nokuhlanganiswa kwamandla avuselelekayo kuzobeka ikusasa laleli sektor.

I-Haidi Environment (Tianjin) CO., LTD ibonisa ukuzibophezela ekuqanjweni kwezinto ezintsha nasekusimameni emakhemikhali okwelapha amanzi, isekela izitshalo zokukhipha usawoti emanzini emhlabeni wonke. Ababambiqhaza okubalwa phakathi kukahulumeni, izimboni, namaqembu ezemvelo kufanele babambisane ukuze batshale ezinsizakalweni ezisimeme zokukhipha usawoti emanzini, baqinisekise ukuthi kunamanzi azobuyela emuva ezizukulwaneni ezizayo.
