Madesiccant zvinhu zvinotora hunyoro kubva munharaunda, zvichiita kuti zvive zvakakosha mumaindasitiri akasiyana-siyana kuchengetedza kunaka kwezvinhu nezvinhu. Pakati pemadesiccant akawanda aripo, alumina inoshanda inoonekwa zvakanyanya nekuda kwehunhu hwayo hwakasiyana uye kushanduka-shanduka kwayo.
Alumina yakakamurwa imhando yealuminium oxide ine maburi akawanda, inogadzirwa nekupisa nealuminium hydroxide. Maitiro aya anowedzera nzvimbo yayo yepamusoro uye kugona kwayo kunyungudutsa mvura, zvichiita kuti ive desiccant inoshanda. Iine nzvimbo inosvika 300 m²/g, alumina yakakamurwa inogona kunyudza huwandu hwakawanda hwemvura, zvichiita kuti ive yakakodzera kushandiswa uko kudzora hunyoro kwakakosha.
Imwe yenzira huru dzekushandisa activated alumina ndeyekuomesa magasi nemvura. Mumaindasitiri, inowanzo shandiswa kubvisa hunyoro kubva mumhepo yakamanikidzwa negasi rechisikigo, kudzivirira ngura uye kuona kuti michina inoshanda zvakanaka. Pamusoro pezvo, activated alumina inoshandiswa mukugadzira makemikari akachena zvakanyanya nemishonga, uko kunyangwe hunyoro hushoma hunogona kukanganisa kunaka kwechigadzirwa.
Alumina inoshandawo zvakanyanya muindasitiri yekuchenesa mvura. Inoshanda zvakanaka mukubvisa fluoride nearsenic mumvura yekunwa, zvichiita kuti ive chinhu chinokosha mukuchenesa mvura. Kukwanisa kwayo kunyudza tsvina uku ichichengetedza mwero wakaderera wekubvisa mvura kunoita kuti mvura yakabatwa irambe yakachengeteka kunwiwa.
Uyezve, alumina inoshandiswazve inogona kushandiswazve. Inogona kuvandudzwa nekudziisa, zvichiita kuti ibudise hunyoro hunotorwa uye ishandiswe kakawanda. Hunhu uhwu hahungoiti kuti ive inodhura zvishoma chete asiwo isingakuvadzi nharaunda, sezvo inoderedza marara ane chekuita nezvinobvisa mvura zvinoshandiswa kamwe chete.
Mukupedzisa, alumina inoshanda idesiccant ine simba ine mashandisirwo akasiyana-siyana mumaindasitiri akasiyana-siyana. Kugona kwayo kunobata hunyoro, pamwe chete nekugona kwayo kushandiswazve, kunoita kuti ive chishandiso chakakosha chekuchengetedza mhando yezvigadzirwa uye kuchengetedzeka munzvimbo dzinobatwa nehunyoro.
