Fluoride ma'adinai ne mai guba. Ana yawan samunsa a cikin ruwan sha. Matsayin ruwan sha na duniya na yanzu don fluoride wanda Hukumar Lafiya ta Duniya (WHO) ta kafa shine 1.5 ppm. Matakan fluoride masu yawa na iya haifar da fluorosis na hakori da kwarangwal, don haka dole ne a cire yawan fluoride daga ruwan sha. Daga cikin iri-irisinadaran maganin ruwaakwai, polyaluminium chloride (PAC) shine zaɓi na farko don cire fluoride. Ikon cire fluoride na PAC ya samo asali ne daga sinadarai na musamman da tsarin aiki. Bari mu bincika tsarinsa, fa'idodi da aikace-aikace.
Hanyar aikin polyaluminium chloride:
Polyaluminium chloridewani inorganic coagulant samu ta hanyar dauki na aluminum hydroxide da hydrochloric acid. Ana amfani da shi sau da yawa azaman flocculant a cikin ayyukan kula da ruwa na birni da masana'antu.
Polyaluminium chloride electrostatically adsorb da haɗuwa da fluoride ions don samar da barga iri-iri. Wannan sai ya ƙara haɓakawa kuma yana haifar da fluoride na aluminum maras narkewa.
