Ukuchitha kwamanzi kuyisisekelo esikhulu, njengokuthi manzi asithile nasebenzisa ngasinye siyakwakha nokubheka. Bona izinto eziyinkulu ezincane okungatholakala, njengamanzi, izinyawo ezincane nezinye izinto ezithintela ukuzwa. Kufuneka sibe nemisebenzi yokususa lezi zinto. Indlela eyodwa enobukhono iyasebenzisa i-PAC, okuyindlela yamakhemikali ekususa izinto eziyinkulu ezincane ukuze kubhekwe ngokulinganayo. Le ndlela iyichitha, okusho ukuthi sifaka umbala wokuphakamisa i-PAC kumanzi. Kuyilungiselelo lokufaka indawo eyodwa ekufakweni ukuthi lizwele! Uma akukho ukuchitha okuhle kwe-PAC, amanzi angakwakhi kahle njengokufanele. Kuyisisekelo esikhulu, futhi sizihamba ngokuvuma kule ndlela uDinghui ukuthi le ndlela ibe yilungiselelo lokufana ngokulinganayo.
Ukuchitha amanzi ngokupheleleyo kanye nokubophelela kuyisimo esikhulu, futhi akukho mhlawumbe wokuchitha. Amazi abuyela emizini eyodwa njengamazibuko noma amadlaka, futhi umunye umkhomo wamanzi unakha izinto ezihlukene zokuchitha. Ngamanye amaxesha kukhona kuphela izinto zokuchitha ezivela emvula, ngamanye amaxesha izinkambo zokuzalwa ziyakwenza amanzi ayishwe. Kusasa kunezinyawo ezingazwa ngokwesibonelo esingasiziyo esingasiza ukuthi sibulale. Ukukhipha konke okunye amanzi amuhle, izindawo zokuchitha kufanele bakwazi ukuchitha. Lokhu kukuphela kuka-PAC, noma Polyaluminum Chloride. PAC yilokho okungu-superhero wezinto zokuchitha zama- manzi ngoba iyakhumbula izinyawo ezincinci ezisemphakathini. Ziyabambana, ziyadala izinhlobo ezinkulu. Lezi zinhlobo ziyakwazi ukuthi zithathelwe noma zichithelwe ngokuthatha noma ngokuchitha. Isimo esifanele akukho ukuthi ubhalele i-PAC ngaphezu kwesilinganiso; kufanele ubhalele isilinganiso esifanele. Uma ubhalele okuncane, akusebenzi kahle, amanzi ayishwe. Uma ubhalele okuningi, uyayisa i-chemical, kuyabeka isipho sokugcina noma isipho sokuzalwa, futhi kuyathinta isibonelo ngamanye amaxesha. Ngoko ke isilinganiso se-PAC kufanele sibe sesilinganiso esifanele, ngaphandle kokuthi amanzi ayichithwa kangakanani noma ayichithwa ngokuncane. Lokhu kukuthi isistimu yokubhala isilinganiso siyisidingo esikhulu. Isistimu yokubhala isilinganiso siyilokho okungu-sprinkler esihle. Iyavumela umsindo wezindawo zokuchitha futhi ibhalela i-PAC esifanele kulezi zindawo. Siyilokho okungu-chef othatha izinkambo zokuvula isikhashana; akukho mhlawumbe wokuthi uthathe isalti yomshado wokuvula, right? Dinghui ayazi lokhu okuyisidingo esikhulu. Sibona ukuthi kuyisidingo esikhulu ukubophelela amanzi futhi ukuchitha. Isiphumo sakithi esivela ekubeni sizakhiwa izisistimu ziyabonisa ukuthi izinguquko encane zokuchitha ziyathinta isilinganiso se-PAC. Umzekelo, emva kokuvula amanzi ayishwe kakhulu kufanele kubhalelwe i-PAC eningi. Emva kokushiswa kokuvula, amanzi ayishwe kakhulu kufanele kubhalelwe i-PAC eningi. Emva kokushiswa kokuvula, amanzi ayishwe kakhulu kufanele kubhalelwe i-PAC eningi. Isistimu esihle yokubhala isilinganiso iyavumela izinguquko futhi iyashintsha ngokuzenzakalelayo. Lokhu kukhuphela ubungozi be-amanzi, kuyakwazi ukuchitha kusukela ezindaweni zokuchitha kuya kumaqanda. Ukushintsha okuphakathi nokulawula okuphakathi. Uma akukho lokhu, abantu bafika emhlabeni, asikayi futhi. Sihlalise ukuthi konke okunye kufanele kufike amanzi amuhle, thina Amasistimu okudlisa i-PAC kusiza ukwenza lokho kubonakale kwezinkundla.
