“Izigidi zabantu ziphile ngaphandle kothando, akekho ngaphandle kwamanzi!” Le molekyuli yomoya-mpilo efakwe i-dihydrogen yakha isisekelo sazo zonke izinhlobo zokuphila eMhlabeni. Kungakhathaliseki ukuthi kuphekwa noma izidingo eziyisisekelo zokuhlanzeka, indima yamanzi ayisathathelwa indawo, njengoba ukuphila kwabantu bonke kuncike kuyo. Kulinganiselwa ukuthi abantu abayizigidi ezingu-3.4 emhlabeni wonke bayafa minyaka yonke ngenxa yokuntula ukufinyelela emanzini okuphuza ahlanzekile. Ukunikeza amanzi okuphuza aphephile kuseyinselele yomhlaba wonke engaxazululwa yi-chemistry kuphela. Njengenzuzo esintwini, imboni yamakhemikhali iqhamuke namakhemikhali ahlukahlukene okwelapha amanzi azothuthukisa ukufinyelela emanzini okuphuza ahlanzekile.
Ayini amakhemikhali okwelapha amanzi?
Incazelo yeamakhemikhali okwelapha amanzikunganikezwa ngemigqa emibili, nokho, lokhu akwanele futhi kungaba yinto engacabangelwanga uma bekungenziwa. Ake sichaze kafushane ukuthi yini esenza sithembele kumakhemikhali okwelapha amanzi.
Ngesikhathi esifanayo, isidingo sokuphepha namanzi ahlanzekile siyakhula ukuze kuhlangatshezwane nezidingo zabantu futhi kusekelwe imisebenzi yezimboni. Ngokusheshisa kokukhula kwamadolobha kanye nentuthuko yezomnotho, ukuhlinzekwa kwamanzi kwamanje akukwazi ukuhlangabezana nesidingo esikhulayo. Ngakho-ke, imboni yamakhemikhali isebenzisa izindlela ezintsha zokwelashwa kwamanzi ukuze kwenziwe amanzi atholakale ukuze asetshenziswe njengokuphuza, ukupheka, ukunisela, kanye nokusetshenziswa kwezimboni, ukubala ezimbalwa. Izindlela zokwelashwa kwamanzi zisebenzisa izinqubo ezine eziyisisekelo, okuhlanganisa ukwelashwa kwamanzi abilayo, ukwelashwa kwamanzi okupholisa, ukuhlanzwa kwamanzi, kanye nokwelashwa kwamanzi angcolile. Izinto ezisuswa ngesikhathi sokwelashwa kwamanzi ziyizinto eziqinile ezilengayo, amagciwane, isikhunta, amabhaktheriya, ulwelwe kanye namaminerali. Le nqubo ihilela izindlela zomzimba nezamakhemikhali.
Amakhemikhali avamile okwelapha amanzi
Amakhemikhali ayisisekelo enkambisweni yokwelapha amanzi yilawa: ama-algaecides, i-chlorine, i-carbon dioxide, i-hydrochloric acid, i-soda ash noma i-sodium bicarbonate, ngaphezu kwamakhemikhali angenhla, amanye amaningiamakhemikhali okwelapha amanziKusetshenziswa ama-coagulant, ama-flocculant, i-Industrial grade chitosan, i-DADMAC, i-Water Decoloring Agent, i-Polyacrylamide, i-Chemical Polyamine 50%, i-PolyAluminum Chloride, kanye ne-Aluminium Chlorohydrate, njll. nazo ziyizingxenye ezibalulekile zezindlela zokwelapha amanzi.
Yamukela imboni yokwelapha amanzi yesikhathi esizayo
Imboni yokwelapha amanzi idlala indima ebalulekile ekuhlinzekeni ngamanzi ahlanzekile nasekuvimbeleni izifo ezahlukahlukene ezihlobene namanzi emhlabeni jikelele. Ngosizo lwamakhemikhali okwelapha amanzi amasha kanye namanye amakhemikhali ahlobene nawo, amanzi avela emanzini olwandle, emifuleni engcolile kanye namanzi angcolile manje asephephile ukusetshenziswa ngabantu.
Ngiyazibuza, ziyiniamakhemikhali okwelapha amanzi? Ungawasebenzisa kanjani amakhemikhali okwelapha amanzi? Izixazululo zokwelashwa kwamanzi? Noma unenkinga efanayo? Ungasithinta futhi ukuthola imininingwane yomhlinzeki wamakhemikhali okwelapha amanzi oseduze nawe. Imikhiqizo inezitifiketi ze-ISO9001, ISO14000 kanye ne-SGS. Umkhiqizo osezingeni eliphezulu, intengo efanelekile. Ikhwalithi kuqala, isevisi kuqala. Ngilangazelela ukubambisana nawe isikhathi eside. Umkhiqizo awunayo i-formaldehyde chemical agent, futhi awunakho ukucasuka kwesikhumba kanye nobuthi obuphansi. xhumana manje Umhlinzeki wamakhemikhali ochwepheshe okwelapha amanzi ovela eShayina. Thola okunikezwayo kwakamuva.
