Izihlanzi zamanzi ane-alkali, amadivaysi alungisa i-pH yamanzi futhi athuthukise izakhiwo zezempilo zamanzi okuphuza, athole ukusetshenziswa okubanzi ezindlini nasemabhizinisini eminyakeni yamuva nje. Umsebenzi wabo oyinhloko ukuguqula amanzi kampompi ajwayelekile abe amanzi okuphuza amaminerali-anothile, ane-alkali kancane ngobuchwepheshe bokuhlunga okuningi kanye nokusamaminerali. Ukuqonda izingxenye zabo kubalulekile ekuthuthukiseni ukusebenza kwedivayisi nokuhlangabezana nezidingo zabasebenzisi.
Izihlanzi zamanzi ane-alkali zihlukaniswe zibe izingxenye ezintathu: iyunithi yokwelashwa ngaphambi kwesikhathi, imojula yokuhlunga okuyisisekelo, kanye nesakhiwo samaminerali. Iyunithi yokwelapha ngaphambilini ngokuvamile ihlanganisa ingxenye yesihlungi sikakotini se-PP kanye nongqimba lwekhabhoni olucushiwe. Eyangaphambili ibamba ukungcola okukhulu okufana nodaka nokugqwala, kuyilapho lokhu kugcina kudonsa insalela ye-chlorine, izinto eziphilayo, namaphunga, iqinisekisa ukuzinza ezinyathelweni zokuhlunga ezilandelayo. Imojuli yokuhlunga eyinhloko isebenzisa i-RO (reverse osmosis) noma ulwelwesi lwe-ultrafiltration, ngokukhetha isusa izinto eziyingozi njengezinsimbi ezisindayo namagciwane kuyilapho igcina amaminerali anenzuzo njenge-calcium ne-magnesium. Amanye amamodeli aphezulu-ahlanganisa iyunithi ye-electrolysis kulesi sigaba ukuze kulungiswe i-pH yamanzi ibe ileveli ye-alkaline kancane (pH 7.5-9.5) ngokusebenzisa i-ionization.
Izakhiwo ezenziwe ngamaminerali ziyi-innovation eyinhloko kuzihlanzi zamanzi ane-alkali. Imiklamo evamile ihlanganisa itshe lezokwelapha, i-tourmaline, noma izakhi zokuhlunga amaminerali emvelo. Lezi zinsiza zikhulula kancane ama-ion ane-alkaline (njenge-potassium, i-sodium, ne-calcium) ukuze kuthuthukiswe izinsalela ezine-asidi futhi kugcwalise izakhi ezibalulekile zokulandelela. Ukwengeza, ezinye izisetshenziswa zihlanganisa amajeneretha e-ion angemuhle noma amabhola-e-ceramic akude ukuze kuthuthukiswe umsebenzi wamanzi nokungeneka.
Inqubo yokuhlanganisa inamathela ngokuqinile ezimisweni ze-fluid dynamics ukuze kuqinisekiswe ukuxhumana okuqinile phakathi kwezingxenye kanye nendlela yokugeleza kwamanzi enengqondo ukuze kugwenywe ukulahlekelwa kwengcindezi kanye nokungcoliswa kwesibili. Ngokufanisa ngokunengqondo ukulandelana kanye ne-porosity yezihlungi zemidiya ehlukene, izihlanzi zamanzi ane-alkali zingathuthukisa ukunambitheka futhi zikhulise izinzuzo zezempilo kuyilapho ziqinisekisa ikhwalithi yamanzi. Ngokuzayo, ngokuthuthuka kwesayensi yezinto kanye nobuchwepheshe bokuhlunga, izingxenye zezihlanzi zamanzi ane-alkali zizoqhubeka nokuguqukela ekuhlakanipheni nasekunembeni.
