Inzwa yokugcwala kwamanzi

1. Ukusetshenziswa kohlelo lokuqapha ikhwalithi yamanzi oluthuthukisiwe

Ekuqaleni kuka-2024, i-US Environmental Protection Agency (EPA) yamemezela uhlelo olusha lokufaka izinhlelo zokuqapha ikhwalithi yamanzi ezithuthukisiwe, okuhlanganisa nezinzwa zokungcoliswa kwamanzi, ezweni lonke. Lezi zinzwa zizosetshenziselwa ukuqapha ikhwalithi yamanzi okuphuza nawomhlaba ukuqinisekisa ukuphepha komphakathi. Ngokudluliswa kwedatha ngesikhathi sangempela, lezi zinzwa ziyakwazi ukubona izinguquko ekuqongeleleni kokungcola emanzini ngesikhathi.

2. Ukusetshenziswa kwenzwa yokungcola ekuniseleni kwezolimo

Kwa-Israyeli, abacwaningi bathuthukisa uhlobo olusha lwenzwa yokuvuvukala ikakhulukazi yokuqapha ikhwalithi yamanzi ekuniseleni kwezolimo. Ucwaningo lwamuva lubonisa ukuthi ukuqapha ngesikhathi sangempela kokuvuvukala kwamanzi kanye nezinye izilinganiso, njenge-pH kanye nokuqhuba, kungathuthukisa ngempumelelo ukusebenza kahle kokunisela futhi kunciphise imfucuza yamanzi. Lobu buchwepheshe buthole ukunakwa okukhulu embonini yezolimo futhi kulindeleke ukuthi busetshenziswe kabanzi esikhathini esizayo.

3. Ukusetshenziswa kumaphrojekthi okuqapha ikhwalithi yamanzi asemadolobheni

Uhlelo lokuphathwa kwamanzi emadolobheni eSingapore lusanda kwethula izinzwa eziningana zekhwalithi yamanzi engcolile ukuze ziqaphe izinguquko zekhwalithi yamanzi emifuleni edolobheni. Ukwethulwa kwalobu buchwepheshe kusiza ukuhlonza ngokushesha imithombo yokungcola nokuthatha izinyathelo ezifanele. Lolu hlelo luwukuphendula izinselele zekhwalithi yamanzi ezilethwa yinqubo yokwakha amadolobha ukuqinisekisa impilo nokuphepha kwezindawo zamanzi zasemadolobheni.

4. Ukuqapha ukungcoliswa kwamanzi kumaphrojekthi ezemvelo

E-Afrika, amazwe amaningana aqalise ngokubambisana iphrojekthi yezemvelo ehlose ukusebenzisa izinzwa zekhwalithi yamanzi evundile ukuqapha izinguquko zekhwalithi yamanzi emachibini nasemifuleni ukuze kulwiwe nokungcoliswa kwamanzi kanye nokuwohloka kwemvelo. Le modeli yokubambisana isekelwa yizimali zomhlaba wonke ukukhuthaza ukuphathwa kwamanzi okusimeme.

5. Ukuqapha ukukhukhumala kuhlanganiswe nobuhlakani bokwenziwa

E-UK, abacwaningi bahlola amathuba okuhlanganisa izinzwa zekhwalithi yamanzi e-turbidity kanye nobuhlakani bokwenziwa (AI). Umgomo wabo ukusebenzisa ama-algorithms okufunda komshini ukuhlaziya idatha enkulu yekhwalithi yamanzi ukuze kubikezelwe ngokunembile izitayela zekhwalithi yamanzi. Ucwaningo kulindeleke ukuthi luhlinzeke ngamathuluzi nezindlela ezintsha zokuphathwa kwamanzi.

Fingqa

Ukusetshenziswa kwezinzwa zekhwalithi yamanzi okugcwala kuyanda njalo, futhi imizamo yamazwe ahlukahlukene ekuqapheni ikhwalithi yamanzi, ukuvikelwa kwemvelo kanye nokuphathwa kwemithombo yamanzi ikhombisa ukuthi ukubaluleka kobuchwepheshe bokuqapha ukugcwala kuyanda. Lokhu okungenhla kuyintuthuko yakamuva kanye nezindaba mayelana nezinzwa zekhwalithi yamanzi okugcwala emhlabeni. Uma udinga ulwazi oluningiliziwe noma ukhathazekile ngesenzakalo esithile, ngicela ungazise!

Sinezinzwa eziningi ze-turbidity ezinezimo ezahlukene zamamodeli, wamukelekile ukubonisana nathi.
